Danny and Constantine's deal.

Inspired by @stealingyourbones 's prompt per @silverblueglitter 's request.

Read on ao3. Masterpost.

When the boy had sought him out, reeking of Death Magic John had wanted to say no on principle.

You don’t get that aura from being involved in normal stuff. John didn’t want to imagine what the boy did to exude such a strong presence and he’s the one who regularly tricks and gambles with Demons. At first he had been convinced the boy had a curse on him or that he was possibly possessed by an angry spirit (and how ironic that had been in retrospect).

To say that John had been taken by surprise was an understatement. One moment he was sipping on a truly awful cup of coffee, while smoking a cigarette and looking at a British newspaper and the next the boy appeared like out of thin air, settled in the chair opposite to him.

The problem? John had been in the House of Mystery — which meant that no one should have been able to find him there. Bloody hell, John had constant problems finding it himself, considering it was sentient and would manifest in different places just to spite John — at least that’s how it felt to the man.

He had startled, his coffee swapping over — but before it could stain either his newspaper or his dress shirt it froze in the air. The Death Magic surrounding the boy almost seemed to spike for a moment.

“Blimey!” John cursed out. “How in Satan’s name did you get in here, mate?”

“I just walked in.”

“You-” John felt himself fuming, before his voice dropped into something falsely calm. “You just walked in?”

“Yes.”

John let out another string of curses before he grabbed the cup with the frozen coffee still inside and threw it at the wall, shattering it. The House of Mystery shifted around them, only the coffee table and two chairs with them on them remaining and taking his pack of cigarettes with it as if to laugh at his misery.

“That feels like a bit of an overreaction, but who am I to judge,” the boy said with a shrug.

John groaned, head in his hands before he collected himself. Okay. Whatever. Taking the last drag of his cigarette he put it out by twisting it on the coffee table.

“So,” he started. “What do you want?”

“A friend of yours told me that you know your way around spells and magic.”

“I don’t have friends,” John stated, deathly calm.

The boy gave him an innocent, but impish smile that screamed “Welp, what can you do?”

“Get lost kid,” John said. “I’m nothing but a con-man.”

“A con-man that lives in a magic house that changes its assortments of rooms as it pleases.”

John narrowed his eyes. Now thinking back, the room he had been in before the boy appeared hadn’t been next to the front door. Not even near it. The House Of Mystery once again changed around them as if to confirm the boy’s words.

“You just walked in?”

“I just walked in,” the boy agrees.

John leaned back to stare at the ceiling, contemplating what he did to deserve this. No — cross that, he knew exactly what he did to deserve this.

“I always knew you’d get me, John. I said so.”

He shook his head to disperse the memory before he leaned back even further, settling his feet on the table just because he could.

“So,” he prompted.

“So,” the boy echoed back.

Suddenly the table beneath his feet disappeared and John flailed as he lost his balance. The chair toppled and he crashed to the floor. The boy suppressed his laughter as John peeled himself off the floor.

“Blummin’-“ John bit back another curse.

“You know you almost seem like a supernatural Doctor Who — only your Tardis hates you,” the boy snickered.

“Ha, ha,” John deadpanned as he picked up the chair and let himself fall into it. “Very funny.”

The boy’s expression changed from amused to serious as he looked John in the eyes.

“Become my mentor.”

“Not a chance in hell,” John scoffed. “Go bother someone else.”

“I don’t want someone else.”

“Tough luck.”

They almost seemed at a stalemate for a moment as the boy paused to think.

“What I give you something in exchange,” the boy offered.

“No offense mate,” John said, “but I doubt you have anything I’d be interested in. You’re what? 12?”

The boy scowled.

“I’m 14.”

“Close enough.” John waved him off. “I’m not a babysitter.”

“I know that for most magic users, the higher and more difficult the spell the more dire the consequences,” the boy suddenly says before John can open a portal to throw him out. “Some people just have the talent and big magic reserves — but I don’t think you are one of them.”

“Hey,” he warned, but the boy just continued to smile at him, not daunted by his tone.

“I can solve your problems.”

John squinted his eyes as he crossed his arms. He knew that his magic reserves were minuscule — honestly that’s the reason why he didn’t try to depend on magic if he could. Why deplete them and risk over exhaustion if the right words have the same effect?

“And exactly how would you do that?”

The Death Magic around the boy flared for a bit as he produced a green glowing ball of energy. John doesn’t need a spell to be able to tell that it could power his spells and that he could use it to fill up his magic reserves if need be.

“With this.” He closes his hand, the orb disappearing. “In exchange, teach me.”

“What? How to use Death Magic effectively?”

The boy rolled his eyes.

“No,” he disagrees. “I mean manipulation. Show me how you were able to swindle Demons and get away with your life.”

John grinned.

“Deal.”

John barely evades an attack as he picks up the phone.

“Do you not watch the news, brat?” he questions through huffs of air. “This is a bad time.”

“You’re like a cockroach, I’m sure you’ll survive,” Danny sounds bored and John doesn’t even have the time to feel outraged — moments like these are when he regrets agreeing to Danny’s deal. The boy is more trouble than it’s worth.

He groans as he is forced back to where the rest of the Justice League Dark is fighting.

“So?” he prompts once again.

“So,” Danny says, cheekily.

“Can we for once not do that while I’m fighting for my life?” John hisses and Danny cackles.

“Fine, fine,” he agrees. “I just wanted to tell you some good news.”

John knits his eyebrows together as he casts a spell with one hand — he isn’t trusting that one bit. Danny has a way to get into trouble and John is often the one who has to get him out of it. Honestly he would think his lessons on manipulating are failing considering what a bad liar he is — if he didn’t know the boy has been actively manipulating him into helping him. At least he got something out of it.

He grabs into his pocket and pulls out the condensed energy from Danny and absorbs it, sighing in relief when his magic reserves get filled up again. That was close.

“Spit it out already,” John huffs out.

“Well you said I’m not utilizing what you are teaching you, so I decided I should do something fun-” Oh no. “So I asked around and oh and behold — I got myself a ticket to a very special Poker Night.”

“And?”

“And now I’m the proud owner of 70% of your soul!”

John blankly stares at the phone in his hand before he puts it back up.

“You little-”

The line beeps and he’s about to throw his phone at the next enemy when a sudden voice behind him startles him.

“Sorry your expression was just too good to pass on,” Danny snickers. “I needed to see it in person.”

“HAVE YOU BEEN HERE THE WHOLE TIME?”

Danny leans back, floating in the air as he shrugs.

“Maybe, or maybe not.”

John gets the sudden urge to strangle the boy — never mind that’s just how it always is. He pinches the bridge of his nose as he breathes out slowly.

“Constantine,” Zatanna appears next to John and he doesn’t yelp — thank you very much. “Who is your friend?”

“He is not my friend,” John says blankly while Danny chirps, “I’m the major shareholder of his soul!”

John tries to smother the boy with his hand, but Danny just cackles. He withdraws his hand, disgusted after the teen licks it. They are gathering the attention of the rest of Justice League Dark who are still fighting and trying to hold back the invasion.

“Ah,” Zatanna sounds awkward. “I wasn’t aware you are a father, Constantine.”

Danny bursts out in laughter as John stares at the magic user in bafflement.

“Why do I even try?” John complains as Danny pats the man’s back, still snickering. John searches through the pockets of his trench coat and pulls out his flask. “I can’t have this conversation while sober.”

Danny snorts as John empties the flask.

“You guys need help?” Danny questions as he looks around the battlefield. Of course he would be excited about this.

John sighs, but gives his permission anyway.

“Knock yourself out.”

Danny whoops and absolutely decimates the entire invasion fleet.

Danny’s right leg bounces up and down as he looks at the clock. Just 10 more minutes until lunch break — then he can slip away. Constantine had relentlessly called him the past hour which could only mean the man is in need of new ectoplasm. He can only hope that the situation isn’t too dire. He chances a look at his phone and winces. 15 missed calls.

“Daniel Fenton.”

Danny freezes in his spot and slowly looks up. Mr. Lancer is looking down at him with narrowed eyes and crossed arms.

“What is so important that you can’t pay attention to my class?” The man holds out his hand. “Phone. You’ll get it back at the end of the day.”

Danny sighs as he feels the man’s disappointment. There he goes — and he had been doing so well lately now that he figured out how to deal with his roster of rogues.

Just as Danny is about to place his phone in his teacher’s palm it lights up with another call. Mr. Lancer frowns at the name and it’s with horror that Danny realizes that he saved Constantine as “Con-Man”. Before he can stop the man he accepts the call, turning it on speaker.

“Danny.”

Oh fuck, Constantine sounds pissed.

Danny can’t help but feel guilty. He knows Constantine had survived even before Danny provided him with energy for his spells — but he also knows the man is slowly starting to depend on the extra magic boost.

“I called you 20 times!”

“16,” Danny can’t help but correct.

“You little brat-”

“I’m in class,” Danny interrupts meekly.

Danny can practically hear the moment Constantine realizes what power he holds as his voice turns from angry to amused.

“I see,” he says simply. “I need a new delivery.”

Danny sinks deeper into his seat as the man continues, wanting nothing more than to use his powers to turn invisible and disappear.

“I’ve run out and you know that your stuff is the best.”

Danny closes his eyes. This is karma for all the times he trolled Constantine, isn’t it? He’s purposefully phrasing it in a suspicious way — hell without context it sounds like Danny is selling him drugs.

Danny cringes as he answers, inadvertently making it worse, “I’ll get you the next batch as soon as school is over.”

“Good.”

The line goes dead and the silence is deafening. Danny doesn’t meet Mr. Lancer’s eyes.

“Class is dismissed,” the teacher says. “Danny, please stay back.”

Danny lets his head fall against his desk as he groans.

What follows are the most embarrassing and awkward 15 minutes of his life as Mr. Lancer lectures him and sends him into the break with a “Don’t do drugs” pamphlet.
