Fish Are Friends Not Abominations

The entire Justice League have been on edge lately watching as a giant creature the size of planet dart around the Milky Way galaxy in an almost panicked state. Despite it's very appearent size it hasn't done anything harmful, passing through planets and stars with intangibility.

Constantine on the other hand was freaking the fuck out. There was a giant realms being with a crazy amount of power searching for something and it felt like the universe itself was holding its breath. He was honestly at his witts end when he felt it.

"YOU! What do you have?" He stopped his pacing to look at Batman's traffic light child.

"That's none of your concern." Robin snapped back.

"Robin." Batman's voice cut through their little conversation. By now every JL memeber was watching them.

"It's nothing–"

"Oh yes it is, now let me see it."

As if on que a tiny glowing humanoid creature popped into view ontop of Robin's head cooing and making warbled noises.

Constantine paled.

Robin took the being from his head and held it in his arms, pulling out a batarang and giving it to the thing which then began to bite it.

"Robin." Batman started, voice firm but sounding tired.

"This one found me first." He countered.

"It doesn't matter how you found it, we need to–" Constantine's words were cut off as the large creature released a noise that sounded almost like a whale but something like warbled speech mixed into it. What happened next sent his heartbeat into a marathon and his stomach to a deep trench.

Robin's little creature stopped chewing on its toy and responded with a cry of its own.

Welp they were fucked now.

The large creature's head snapped to their direction, eyes directly on the watchtower as if it could perfectly see them from such a distance and sped towards their location.

Tim: Can I help you? Four-year-old Danny: No, I'm fine, thank you for asking. Tim: I doubt that bud. Why are you here? Danny:What's it to you? Tim: It's MY office???? Danny: It is? You're Timothy Drake-Wayne? Tim: Yes Danny: Great. My mom told me to give you this. *hands over a sealed file envelope* Tim: .....This says you're my son. Danny: Yeah Tim: I'm nineteen, that means you were born when I was fifteen Danny: Yeah Tim clicking phone intercom: Tam, can you please call my lawyers, a team of DNA analysts, and oh, an ambulance for me? Tam: Why boss? Tim: I'm going to faint. Hey can you also get Bruce in here to babysit his grandson? Thanks, you're the best. *THUMP* Danny: I like you, unconscious father.

Clearly the correct answer

MASTERPOST (for the full series / FAQ / reference sheets)

[radiance1]

When the Justice League heard of Phantom, they believed they had to act quickly. Based on what they were told by the GIW, a branch of the government they had no knowledge of previously (Batman is working to correct that), the ghost was dangerous and extremely powerful.

A ghost that terrorized a small town that they GIW have tried-and failed- on numerous occasions to send back to the Ghost Zone. The GIW wouldn't have come to the Justice League for help if it were just that, but based on what they have claimed Phantom has achieved an inexplicable rise in power after having met with the King of ghosts himself.

If what they say is true, then ghosts could potentially invade and cause an all-out war with humanity that the Justice League would rather much avoid thank you.

Negotiations for peace or understanding have been repeatedly rejected and the GIW has been led to believe that Phantom has done something to the Fenton couple. The leading ecto-biologists in the world, years of research suddenly wiped clean off and acting much more cordial towards the ghost.

A complete 180.

So much so that you could even claim them to have been mind controlled. Which isn't outside the realm of possibility due to ghosts having an innate ability to overshadow others and control them.

Perhaps even the entire town has fallen under Phantom's control. Even another ghost, who had just been recently opposed to Phantom, has fallen under his control.

So the Justice League had to act fast.

---

Danny was fucked.

He could tell that very, very well. He still didn't have his entire new... dragon thing... under control very well, mostly sticking a half human like form. His powers were stronger yes but he couldn't really control them well.

Which is kinda why he's fucked.

Danny has never heard about the Justice League before, mostly because he had recently found out that apparently Amity Park was isolated. Like, extremely. Basically it's own little world cut off from the rest.

So when they appeared with the GIW he thought, hey, maybe they were finally changing their white suit shtick.

He didn't expect them to be extremely well-trained, have supernatural abilities or magic. Along with their usual tech well.

Yea.

Danny was fucked.

And he was very, very scared.

He's already died once but that didn't mean he wanted to die again, and he knows that he would probably be heavily experimented on if the GIW actually got their hands on him.

He was alone. He was surrounded. He was outnumbered. And he was oh, so very scared.

His family and friends had already fallen (thankfully not dead, just unconscious he thinks) and Vlad was occupied elsewhere, also fighting.

So Danny was alone.

No one would be coming to help him.

So what did he do?

He opened his mouth and did something he didn't do often. Despite that he could see that they somewhat recognized what he was about to do and tried to find cover.

Danny wasn't aiming at them.

He pulled his head back, mouth aimed at the sky.

Danny wailed.

It was waaaay more powerful than he had originally thought, so he was glad he aimed it at the sky.

As soon as it was over he felt drained, swaying on his feet and trying to use his tail to steady himself and not fall off his own claws.

They didn't know what was happening.

Danny just hoped it worked.

---

Neither the Justice League nor the GIW knew why Phantom shot one of his most powerful attacks up into the sky, but they did see the opportunity it presented.

Phantom was weak. Looking like he would fall off his own feet and fall unconscious.

They had to act quickly.

But before they could, from right where Phantom had wailed into the sky.

It cracked.

And continued to crack.

Until a large hole appeared in the sky, leading into a dimension of endless green.

The Infinite Realms.

They believed Phantom was trying to retreat.

They were wrong.

Two roars came from the portal, forcing everyone to cover their ears.

Then.

Something came out of the portal.

A long, serpentine dragon flowed out, flying around the area of the crack before descending down and around Phantom.

Then.

A giant claw grabbed onto the edge of the crack. Pushing against it until it broke, forcing the hole bigger and bigger as a much, much larger dragon stepped out. Standing protectively over the serpentine dragon and Phantom.

A large crown wrapped in flame floating about its head signified its status.

The Ghost King.

Do it for the Plot

I like the idea of Tim and Danny meeting and just clocking each other as little shits TM.

Just causing chaos to everyone in a way that can't really be traced back to them like 'Who? Me? I was busy doing all of these other things I have no idea how I would do that?'

Danny helps Tim get revenge on the bats for all the shit he's had to put up with and being absolute trolls about the whole thing *chefs kiss*

Tim&Danny dragging Ra's body

Damian: "Wha-?"

T&D: "No one will ever believe you"

Danny makes them go invisible

Bats: "Where ya going Tim?"

Tim holding back a cackle:" Oh, it's my anniversary so it's date night!"

Bats: "Anniversary?! We didn't know you were getting serious with someone?"

Tim: "Serious? He's my husband of course I'm serious about him"

Bats: "Wait hold on-!"

Tim: "Gotta go! Can't be late I have to make sure the babysitter has everything they'll need."

Bats: "BABYSITTER!?"

Tim: "Bye bye~!"

(They planned all of it including their 'fake marriage', Danny went back in time with the help of CW who is a troll at heart, and made the legal changes including Dan and Dani as their kids (their de-aged) otherwise someone (Oracle) would have eventually realized that the license is fake. So they went back in time and made it legitimately real)

Danny being Ghost King means that Tim is now also royalty

Tim walking up to John Constantine:" I have your entire soul"

and then just turning around and leaving

John very much felt the very strong Death Energy claiming Tim: "I don't want to be sober right now"

Earth about to be taken over for the 5th time that year by higher beings

Tim walking up late with coffee in his hand: "Leave or I'll call my husband"

Higher Beings very much not wanting to mess with the High King of the Infinite Realms: ᕕ( ᐕ )ᕗ

Just an Idea

[emacrow]

Aquaman was only patrolling the ocean, not expecting a baby mer swimming with the whales along the way.

It one of the few things he would like to do in his free time is to help the ocean sea with minor problems, a seal having his neck stuck with a plastic can holder, a a couple shark with a hook stuck to her fin/nose or tailfin, a couple of trapped rare fish in poacher traps.

He wasn't expecting a small group of whales, mainly a momma whale and two Baby whales to swim by singing their song while hunting a vast enormous group of krills.

Only to hear a tiny little baby mer singing along with them. It was a boy, with chubby lil arms, a beautiful trails of sparkling white and neon green color, fade gray and black tips mer tailwind. A fainted trail of electric shock probably from a mishap by jellyfish tracing from one of his chubby hand down to his body.

Hair white as snow, eyes greener then the grass on land, tanned skin and a odd sliver mechanism purple clock on a necklace that was ticking slowly despite being in deep underwater.

Arthur was going to get closer but the Momma whale Block his view using her vast body after she noticed him getting closer, the two Baby whales hiding behind her along with the baby mer.

Meanwhile Danny as clockwork apprentice until he grows into his state as the ruler of ghost realm and away from noisy observators has been on a mission to keep the timeline in check in other dimensions. Clockwork insisted this form would do the trick

Dc x Dp prompt

Phantom has been apart of the justice league since its beginning. The young man was powerful and had no recorded history of hero work despite clearly being experienced (when mentioned Phantom muttered something under his breath about “Desire”?)

But after an incident involving a shapeshifter and a power disruption, everything The Justice League knows about Phantom gets put in question as he loses his shape shifting and turns into a young teenager. It’s like there’s another Billy Batson situation but instead of turning into an adult, they shape shifted into one.

Meanwhile for phantom, he is mentally screaming. He’s phantom form hasn’t aged in the 7 years he’s had it, it’s not even that ghost age differently, by all dead ghosts standard he is a full adult ghost. He can’t change his form permanently without ether losing his obsession or damaging his core first so he does the next best thing, learn to shape shift.

He can’t do much, just bump up his ghost age to his human one, but it was more than enough until the Justice League found out and don’t listen when he says he really is an adult

Blue Screen

Danny is the type of guy gal ghost to Commit To a Bit. This is very common knowledge

But he may have overdone it this time.

---

Dan and Ellie had met the Red Hood, who seemed yucky. Ellie said this herself. Jason was not amused, and did not appreciate them following him around for the rest of the week.

After a bout of panic, Danny had finally tracked the tykes down. After seeing who they were with, he sighed. Of course those two would. Well he could play at that game.

Danny had popped in and pecked him on both sides of the helmet, leaving a casual lie before legging it.

"Hey hun, thanks for watching the kids. I'll take it from here."

---

It's been a month now, and somehow he has two kids with a notorious crime boss and goes on nightly dates with him.

[noisilyscreechingsong]

Alfred knows Danny from long ago during his secret service days. He always found the other odd, but his company was enjoyable enough to overlook. They were friends for a short while. Danny even saved his life once or twice. However, despite their trust in each other, they didn’t keep in touch. It was like Danny disappeared and he never heard from the jolly man again. That is until Danny showed up at the Wayne manor decades later looking the same as when they parted ways carrying the daughter he talked so much about.

Danny stood on the front porch with a toddler Ellie in his arms. She’s been behaving wonderfully. The new environment gave her curious self something to look at and distract her from a tantrum.

He rings the doorbell awkwardly with her in one arm and a bag of supplies resting on his shoulder.

If things were any different he wouldn’t be here, but he’s got to do what he’s got to do even if it’s the last scenario.

Footsteps can be heard on the other side before it opens to reveal a boy in sweatpants and a hoodie. It’s a little warm for the summer and Danny expects they have an expensive electric bill for this large place.

The kid, Damian Wayne he remembers, scowls. He gives Danny a once over with narrowed eyes.

“How’d you get through the gate?” Damian demands.

Danny blinks and adjusts Ellie on his hip.

“I walked of course.” Damian grows even more suspicious and Danny decides to change the subject. “I’m Danny. Danny Fenton. And this little monster is Ellie. Want to say hello, Ells?”

Ellie looks at Damian for all of three seconds before losing interest.

“No.”

Danny sighs. Yea, he was expecting that answer. It’s her favorite word at the moment.

“Why are you here?” Damian asks.

Straight to the point then.

“I’m looking for Alfred Pennyworth. Is he around? It’s urgent.”

“What is it concerning?” Damian straightens his spine to appear taller but it doesn’t change the head difference.

Danny sets Ellie down on the brick when she won’t stop squirming to be let down. She doesn’t waste a moment wandering away to investigate her surroundings. Damian raises a brow while watching her.

“I’m cashing in that favor he owns me.”

That got the boy’s attention. He studies the adult for a moment before opening the door wider for the both of them to enter.

Danny manages to wrangle Ellie into the house with Damian’s judgmental gaze following them. The bag had slid down to his elbow when he bends down to hold Ellie’s hand to steady her.

It’s as Damian is closing the front door that a man comes around the corner in a butler uniform. The same man he was looking for.

Alfred freezes after registering who was in front of him. The older of the two sighs heavily. Shoulders back and chin high, as expected he approaches this situation with a level head and posh dignity.

“Daniel,” addresses Alfred. “I wasn’t expecting you.”

Danny cringes. He really should have called with a warning but there wasn’t time. He also always hated it when Alfred refused to use Danny’s preferred nickname, a sort of teasing that was consistent. If Alfred was anything, he’s stubborn enough to do what he wants and get away with it.

“Sorry, Alf. Next time for sure.” Danny sends a cheeky grin that doesn’t impress anyone. He glances over at his daughter to see her trying to touch the expensive looking vase on a side table.

“Ellie!” He dashes over to pull her away which immediately starts a struggle war and fussing. He knows if he lets this continue it will turn into a full blown tantrum.

“That’s not ours, we can’t touch it without permission.” She whines in frustration. “Do you want to ask if it’s okay to touch? Gently?”

Ellie thinks about it a second before looking up at him. Danny nods in understanding and turns her a bit to look at the two spectators.

“Toush?” She asks with an adorable chubby arm raised to point at the vase.

“Are you going to break it?” Damian asks with folded arms.

“Master Damian, I’m sure that’s not her intention.” Alfred turns with a smile back to Ellie. “That vase is fragile. Can you be very careful?”

Obviously her answer is a confident nod of the head and immediately trying to reach out again. Danny helps to lift her and hold her wrist steady.

She pets the vase like a kitten, feeling the raised edges of the design with her little hand. After a few long moments Danny pulls her away to set her on his hip like before, earning an annoyed huff in his direction for his efforts.

“Very good, Ellie. I knew you could do it.”

She hides her face in his shoulder and he takes the opportunity to send a look at Alfred. The older man understands immediately and inclines his head before turning to walk further into the house.

“It was nice meeting you,” Danny shoots Damian before following Alfred to what appears to be a parlor a few rooms away.

“I shall fetch some tea.”

Danny shakes his head as he sits.

“No time. I’m in a rush.”

Alfred eyes him up and down before gingerly sitting in the armchair across from him.

“Yes, so I have noticed.”

In other words, spill your guts for abruptly intruding like you have.

“Something…urgent has come up-“

“I assumed as much.”

“-and I know how good you are with kids-“

“Daniel, you cannot expect me to-“

“You owe me,” Danny says firmly. Alfred leans back at the reminder. He knows Danny would never hold that over his head without a good reason. “I have no one else to go to, to look after her. I normally would just take her with me, but I- it’s gotten dangerous. Too dangerous for her.”

He looks to Alfred with desperate eyes. Ellie tries to squirm out of his arms, which reflexively tighten securely around her middle. He can see the dark bags under the younger eyes.

Alfred sighs.

“How long?”

Danny sags and Ellie slips out of her father’s arms as soon as the chance presented itself. Alfred would need to keep a close eye on her in the future.

“A week, two, three tops.”

Alfred sends an unimpressed look and Danny cringes but doesn’t redact his statement.

“Anything I need to know?”

Danny looks down at the hastily packed diaper bag like it had all the answers.

“We’re kind of in the middle of potty training so I threw in some pull ups but those will go quick. She hates carrots. Won’t go to sleep without a bedtime story. Don’t give her any sugar after four or she’ll turn into a monster. Oh, and her powers are coming in so I packed a shield for at night.”

Alfred raises a single eyebrow.

“Could you be more specific?”

Danny waves it off like it was no big deal.

“Just the normal stuff. Invisibility, intangibility, and flight. It’s all very weak and sporadic right now. Keep calm until she figures it out on her own. She’s just learning.”

“So you are leaving a child in my care for an unknown amount of time, a child that can disappear, walk through walls, and fly. Anything else?”

Danny rubs the back of his neck guiltily.

“Why do you always have to make everything sound so…” He sighs heavily, glancing over at Ellie who has managed to take every blanket out of the basket in the corner and crawled in to make a nest out of the materials. He smiles fondly.

“I’ve probably forgotten something, but I know you can handle it. You can take care of her.”

Danny then stands and pulls out a piece of paper, handing it over.

“My number is at the top in case of emergencies. Her favorite stuffy is in the bag, she won’t sleep without it. Her favorite word right now is ‘no’. I wrote down anything I could think of, which you probably can’t even read my chicken scratch…”

Alfred gently takes the paper from his hand and Danny slowly makes his way to the messy corner.

“Hey, Elles,” he says softly, far softer than anything Alfred has heard from him. Usually he was a rambunctious, jovial loudmouth, but right now he was hesitant. Prolonging the farewell they both know needs to happen with how urgent this mysterious problem was.

Ellie looks up for a moment before going back to maneuvering her fort.

“I gotta go away for a while. Alfred here will be watching over you while I’m gone, okay?”

That got her attention. For a child that young, she knew something was wrong, but didn’t know what. And now her dad, her protector, was leaving.

“No.”

Danny folds his lips together, expecting the response but still not ready to go through the hard part of leaving.

“I’m so sorry, baby girl. I am, but I have to go. I’ll be back when I’m finished.”

“No!”

Danny sighs and reaches in to pull her into his arms. She fights him valiantly, but he was stronger and bigger.

“I know. I know. I’m sorry. I’ll be back as soon as I can. I promise.”

They might as well have been empty words for the lack of effect it had on the struggling toddler. Danny sways with her for a few beats until he gets an idea.

“Danielle, look.”

He makes sure she’s watching as he creates a loop of ice, infused with his ectoplasm and therefore, his signature.

“Hold out your hand,” he coax.

She does so with a sniffle and he gently moves the glowing green ghost ice around her wrist to make an indestructible, unmeltable bracelet. He shrinks it until he’s sure it won’t fall off and won’t be too tight either.

“There. Now you have a piece of me wherever you go. Even when we’re far apart.”

She pointedly doesn’t look at him.

“I love you, Ellie. I’ll be back soon.”

He kisses her forehead, breathes in her soft scent, and turns to Alfred. The older man is watching carefully and makes his arms available for a new passenger.

With a deep breath Danny hands her over, Ellie immediately starts whining and tears fall from her eyes.

“Hey, you’ll be okay. Alfred here is a mighty warrior. He’ll keep you safe. I trust him.”

He does his best to wipe away her tears but he has to physically step away when she reaches for him. Instead he looks to Alfred.

Alfred holds her securely and nods in assurance.

“Not to worry. Danielle and I will be too busy to notice your absence.”

Danny smiles at the effort but it doesn’t reach his eyes. He can’t resist petting her head one last time, her pigtails in disarray, and wiping her tears from her cheeks.

“I’ll be back before you know it,” he promises, marking it with another kiss to her head before backing away again. He looks at Alfred sending his gratitude without words. Alfred accepts it with a slight incline of the head. Danny nods once and leaves before he can’t.

The door opens and the young boy from earlier stumbles back with a glare to hide his embarrassment.

“Master Damian-“

Danny holds up a hand to stop Alfred. Of course the boy would eavesdrop, what did either of them expect?

The young father leans down to get eye level with Damian, looking him straight in the eye with seriousness. Damian straightens at the attention.

“It’s very important Ellie is safe and occupied while I’m away. It would mean a lot to me if you would help Alfred do that.”

Damian folds his arms.

“What would I get out of that useless goal?”

“What would you want?”

“Daniel, Master Bruce would not-“

“A knife,” Damian interrupts. “Not just any knife though. It has to be special.”

Danny hums in thought, studying Damian for a moment, almost making the boy squirm.

“Deal.”

He holds out his hand and Damian shakes it after a second of hesitation. Danny nods to the boy, then nods to Alfred, and he’s finally out the door making a portal as he walks from the gentle breeze of outside to the chill of ectoplasm, transforming into his kingly attire as he crosses the threshold.

The GIW had a lot to answer for and he couldn’t hold his subjects back any longer. The United States had declared war against the Infinite Realms and he would be the one to answer.

[noxcheshire]

We do not see enough of de-aged Danny being adopted outside of Bruce and Jason, and maybe like, a small handful of Dick and one Cass.

But I have not seen enough Tim Drake.

LET THAT BOY BE A PARENT.

Let Danny crawl up a roof, through alleys, and under shadows because he wants to either help himself when he returned to his correct age by copying their moves, or just because they are a little cool. Let baby Danny be found by Red Robin who immediately does a full 180 back over to land in front of a little toddler wearing an astronaut onesie.

A little toddler trying to squirrel his way through the roofs opening to escape and failing.

Let Red Robin feel the tilting reality of baby Danny willing to fight him and lying to his face even while trying to whisk away with some stray bat-weapons that have been left all around Gotham.

Let Tim Drake have a small handful of Amity Park feral clawing up his suit, demanding to be held because Tim doesn’t treat him like an idiot, but a very smart toddler that wants attention.

Let Tim Drake have a baby Danny that will try to fly away so he always must wear a baby leash, floating around Tim’s head like a living balloon. If he phases through, aunties and uncles YJ will also be there to catch the stray baby playing at a dog having escaped the house.

Let Tim Drake buy baby clothes and sew in various trackers with Danny eating his way through a messy apple sauce cup, ignoring the invasion of privacy because he is so used to Jazz having done the same thing when he was originally a baby the first go around.

Let Tim Drake accept the glowing greens that seep out from Danny’s fingers because that power is too much for his little body to handle. Accepting, even when the green begins to fade into walls, and objects, clothes, and skin.

Can You Hold This For Me?

Jason is enamored as he watches a beautiful red head lady beat the shit out of the mugger that got too close for her liking.

He was on his way to the local book store to find a good read when he saw a woman with her month old baby being stalked by a man who was obviously hiding a knife in his pocket. Jason immediately crossed the street to put himself between them and the mugger when all of a sudden the man got a little closer and the woman executed a perfectly good roundhouse kick to the man's head while keeping her baby secure.

After the man's body bounced in the alley and hit a trash can she turned to Jason with a brilliant smile that did something to his resurrected heart.

"Can you hold this for me?" She asked before simply putting the baby in Jason's arms before he could reply.

She then proceeded to pick the man up, who was twice her size, and flung him further into the alley before running up to finish her beat down.

A noise brought his attention from the woman to the baby in his arms who was now up and cooing at him curiously.

"Your mom's hot."

Homeless Jason before Bruce him in: Why are you scared of Batman?

Also, homless Danny: I don't want him drinking my blood

Jason: Batman's a vampire!?

Danny: I know! He's so scary!

Jason: Well, aren't you like a half ghost meta? Can't you take him?

Danny: You want me to fight a VAMPIRE!? No thanks.

Batman, watching from above their alley: Those are the kids that are being hunted down by a rouge?

Nightwing: Yeah, there are some rumors Penguin wants their heads. Apparently, Danny helped an entire shipment of traffic victims escape their cages by crashing a crane against the shipping carriers that they were in. Jason was among the victims, so it may have been an attempt to rescue his twin

Batman: They're twins?

Nightwing: According to the word on the street they are. What do you think? We putting them in witness protection?

Batman: No. Danny's meta abilities will have then flag by another ring before long.....Wayne is an emergency foster. He could take them in.

Nightwing: Sounds good to me. Let me tell them that, though. They think you're a vampire, so they may be scared of you.

Batman slightly hurt: Alright.

Nightwing dropping in front ot the kids: Hey there-!

Danny: AGHHHHHH! THE DISCO VAMPIRE! RUN JASON!

Jason: AGHHHHHHHHHHHH DISCO IS SO MUCH WORST THEN A GOTHIC ACADEMIA VAMPIRE!

*Danny and Jason sprinting faster the the Olympics gold medalist*

Dick: Why does everyone hate my discowing outfit.

[hello-eden]

Dead on Main time travel with a mom Danny twist.

Jason calls in a favor from someone on the justice league dark team for help with a case that got magical. the person sends him Danny. it goes well. they're both working very professionally. something happens and they end up back in time in their younger bodies.

Both of them are in the same city that they were working the case on. They are far away from home but Jason is 15 a few months before he finds out about his bio mom and Danny at this time is incubating Dan and Ellie's cores.

Neither of them quite realize the repercussions of what's Happening. The two of them team up to try and get back home. What the two of them don't realize is Danny's friends and family have no idea where he is though they are less worried than the bat family who fully believe Jason is kidnapped.

The two of them go on adventure trying to dodge any local heroes or villains. Eventually the two of them are able to get into contact with Clockwork and Clockwork tells them that they have altered this timeline too much for them to go back. 

The two of them angst about that until they have to get forced out of that because they run into a local hero. I want to say one of the Titans that work with Nightwing because then they recognize Jason but have no reason to know that he's missing.

the two of them then realize that because they're in their younger bodies everyone has no idea where they are. This is when Danny realizes that at that age he is incubating Dan and Ellie which makes him try to split off from Jason.

As Danny's trying to figure out a way to tell Jason what's going on Jason realizes that Danny is getting really sick or at least he thinks is really sick. He's getting tired more easily than before and keeps throwing up. Jason originally thought it was due to stress of the situation but it becomes more and more clear that it is not. They end up having a confrontation which leads to Danny telling him that they are basically pregnant. 

Jason tells Danny that they are not leaving them, especially not after everything that happened. The two of them decide together where to go. The two of them end up deciding the only places that they can go are Amity park or Gotham because of the ambient ectoplasm.

They can go to Amity Park except last time Danny was there it was a bad Fenton parents reveal which led to both Dan and Ellie dead with jazz wheelchair bound as well as Sam and Tucker in comas.

 Or

they could go to Gotham except Jason is probably presumed missing. Having Wayne and bat family connection is probably best for them except for Jason having a falling out in the last timeline as well as knowing that he is supposed to be dead in a few weeks. Jason knows that his death is a major turning point for his family as well as many other things in the timeline.
