Marco’s Bauble Part 8 - a One Piece Mermaid AU Text Story

Another update for Tumblr!

This work goes by On the Courtship of Monkey D. Luffy on AO3, and I’ll be updating over there tonight as well!

A quick question....do people like reading the updates here on Tumblr? Or now that it’s on AO3, would people prefer to read there? And if so, would you be okay waiting for new updates until AO3 catches up? I’m a little torn because I’m not sure if people are enjoying reading on here, and it’s quite a hassle to format for Tumblr, and it’s getting a bit difficult for me to juggle updating these stories on 3 separate platforms...

ANYWAY, in this update, Thatch has some Thoughts, and there is mention of Ace x Luffy.

Continues off of, and should be read after:

What are her 3 sizes?

(For the wedding dress, of course.)

"The fuck! Like I'd tell you!" Thatch roars, startling the blue gull into momentarily leaping off the rail, before it circles back, landing again to peck at his  sleeve to express its displeasure. Thatch ignores it, because he's fuming.

So apparently all of his and Koala's secret debates over whether Marco intentionally proposed or not were for naught, because here's the fucking evidence. And it comes from Izo of all people, because Thatch would recognize that lopsided handwriting anywhere (the man insists that his handwriting is beautiful in his native language of Wano, but he never quite got used to writing any other way).

And well, if Izo, an unrelated third party but professional snooper knows, then Marco himself must know.

And apparently, they're already planning a wedding.

Thatch feels like an idiot. He'd been defending Marco against Koala, and the lil Revolutionary was a tough opponent, one he'd had to chase out of the kitchen with a ladle more than once when he was tired of her word games. Thatch had insisted, like a fool, that no Marco's not that kind of guy, he really isn't the type to play with people's emotions, he would never propose for a joke, nor would he do it seriously without good reason. It must all be an accident, a little misunderstanding, Marco was just ignorant like Thatch himself was!

Except, apparently he did know and it wasn't an accident, and now Thatch feels completely lost because he doesn't know what Marco's thinking at all. Marco, who's not just his his first friend on the Moby, but arguably his best friend; Marco, his brother over several decades; Marco, who Thatch thought he knew better than anyone, except perhaps Pops himself...

Thatch's also pissed, because if Marco wants to start drama after they all reunite and he's introduced to Luffy, that's one thing (not that that would be great either). But right now, they're still near the beginning of Paradise with almost half the circumference of the world to go until even the halfway point, and Marco is WAY on the other side of the Red Line. If this ship explodes in flames or whatever that batshit Revolutionary brother might do, Mister First Division Commander is completely unaffected, but there are plenty of innocents here (like hello! Thatch!) who would find that pretty devastating.

Also, Thatch was the one who passed on that gift to Luffy! Even if he didn't know what it meant at the time...doesn't that make Thatch complicit? And even if not, Marco's strongest connection here is clearly Thatch. If Marco's actions cause chaos, then the blame and responsibility to clean up the mess naturally falls upon Thatch. Which, he definitely did not sign up for.

Pops, Thatch thinks miserably, I thought I was supposed to show them they can depend on us Whitebeards, NOT that us Whitebeards will fuck shit up for them...

But more than anything, there's a shocking large part of Thatch that absolutely balks at just the idea of Luffy getting married. And it's shocking because Thatch shouldn't feel this upset.

Marco, for all the complaints Thatch wants to hurl at him at the moment, is still a really great guy. A guy who, in literally any other situation, Thatch would be the first in line to enthusiastically encourage, and also to congratulate.

And sure, Thatch knows he has a crush, and his little Seastar's carving out a larger home for herself in his heart by the day, but--Thatch admittedly has crushes a lot. Sure, this one feels different, but...Marco, to his knowledge, has never had a romantic crush. He only sometimes but very rarely even has a night out, and Thatch doesn't think he's ever held a relationship longer than three encounters. He's always so serious, so diligent, so sincerely and whole-heartedly dedicated to Pops and his family. He almost never does anything selfish for himself, and Thatch would know.

If, for whatever reason, Marco is genuinely serious about Luffy...then Thatch should, and would, step to the side, regardless of personal feelings. If this is the path Marco wants, then he deserves it, and Thatch will always be the first to say it, no matter how craptastic the circumstances. And Thatch knows that Marco would give his bride the world.

Without them even having met, Thatch doesn't doubt for a second that Marco would make Luffy happy, till the end of her days.

The fact that Thatch knows all this, yet still feels near unbearable reluctance...says more than he's willing to admit.

And so he decides to avoid thinking about the most obvious reason (his own feelings), and instead contemplates his second very compelling reason: Ace.

His littlest brother isn't so great at being honest with himself, and never has. But this, Thatch feels, isn't just a matter of denial.

The boy literally has no clue.

Oh sure, Ace knows he loves his little brother. He makes sure everyone else knows it too, both here on the Merry and back on the Moby once he opened up enough to talk to people. He's so damn proud of her, yet also concerned for her, while also trusting her with his life and more. It's clear to anyone who sees them together that he absolutely adores her.

But it's more than that, isn't it, Thatch thinks. It's in the little gestures, the way Ace raises his arm up without looking at her and she slides under it, also without needing to look at him. It's the casual way they lace their fingers together, like it's nothing, when they're snoozing out on the deck. It's the way sometimes they have unspoken conversations, just staring into each others eyes, before moving forward in synch to meet in the middle to bump their foreheads together in some secret mutual understanding.

It's the reason why Sanji, for all his extravagant flirting, knows when to shut up and return to being a normal human (and, Thatch grudgingly admits, this applies to himself too). It's why Zoro never lets his gaze linger more than two seconds longer than it needs to (but he'll always take those two seconds), why Nami always looks like she wants to sit closer but doesn't, why Koala hasn't said anything when she's probably usually a much more proactive flirter.

Everyone on their crew can see it, except the two in question.

Ace, Thatch thinks, heaving a huge sigh as he looks down at the crumpled note from Izo in his palm. Little brother, you are so fucking in love.

It might not necessarily be romantically. It's certainly not particularly sexually, if Ace's lack of reaction to Lu's aggressive physical smothering is any indication. It could very possibly be platonically.

But either way, there's no room for Sanji, nor Zoro, nor the girls, nor even Thatch himself...at least, until those two figure that out.

Until then, everyone aboard the Merry is here because they love and respect their captains. No one would dare encroach on something so special, yet so potentially immature, not yet ready to be dragged out to be recognized.

Thatch knows Ace has known Luffy for years, he practically raised her. But he was also away at sea for three years. Luffy was a child when he left; she's an adult now.

Thatch once asked him if she had changed at all since he last saw her (Ace most certainly had, according to Deuce). And Ace looked blank, then horribly confused, before saying No...but also, yeah, I guess. Thatch understands; Ace isn't used to not knowing something about Luffy. And something...something had changed.

That something might very well be the thing that needs to be figured out. And for that, Ace hasn't had much time yet, since reuniting with Luffy. Only as much time as the rest of them, in fact. And they deserve time to figure that out, and as the two captains' loving crew, the ASL pirates have an unsaid agreement to watch over them...at least until they have.

(After that, Thatch thinks grimly, it might be open game.)

But of course, there's also the question of Luffy herself, and as much as she's the heart of the ASL Pirates, she's also an enigma. Thatch, for all that he adores her and honestly wants more with her, genuinely has a hard time imagining her as anything but clueless as someone's romantic partner (he's carefully not thinking about anything sexual). It very well may be that the whole "figuring out" that she and Ace have to do...ends up being nothing. And that's fine as well.

Either way, as much as Thatch loves him, there's no way that any of them here on board the Merry will stand to let Marco shatter this delicate...whatever it is that's going on between their captains, that the rest of them are so patiently respecting. Even if it ends up continuing indefinitely.

As strained as it can feel at times, they're comfortable like this. There's the little spark of joy when Seastar gives him a little extra attention, a little burn when Sanji kisses her hand, but comfort in the stability that no one will go any further. If anything it's a nice little spice to their daily lives, just the right amount, and not enough ruin the dish so to speak. This is fine.

Except, that there's just one teeny little problem...

"What did the blue gull bring you today, Commander?"

Thatch doesn't jump, because he's not an amateur and did realize that the Revolutionary was approaching, but perhaps later than he should have. Damn the kid's good at hiding his presence, and Thatch wonders if he'd have noticed at all if Sabo was being serious.

"Just a stupid request from a stupid brother," Thatch says cheerfully as he turns around to face Sabo. The boy isn't even trying to hide his curiosity, his gaze pinned to Thatch's hand.

Thatch contemplates chucking the letter into the sea, but then he realizes he isn't sure Sabo wouldn't just dive after it, and as a devil fruit user, Thatch wouldn't be able to stop him from reading it underwater.

So he casually uncurls his fingers, watches Sabo visibly perk up--before Thatch opens a black hole in his palm, letting the crumpled paper get sucked into the void.

(Perhaps he should be using his power as more than a secure second dimension pocket expansion, but hey, so far it hasn't been so helpful in the kitchen.)

Sabo sags and sulks, rather cutely, Thatch thinks. "You coulda let me see it," he pouts, looking up at Thatch with an expression uncannily like Luffy's. Fuck.

"Collecting intel, Chief?" Thatch winks, expertly hiding his horror that for a moment, he'd actually been tempted. Little sneak.

"Perhaps." Something slightly manic enters his gaze, and alright, that's nothing like Seastar, not so cute after all...

"Nice try, but it's a personal family thing, can't really share," Thatch says, and it's not really a lie.

Sabo grunts, letting it go, before his gaze flicks to the gull, who still has a beakful of Thatch's sleeve. "It waiting for something?"

Thatch sighs. "Yeah, yeah, my response, which I should probably give..." Because, right, Thatch needs to send a message back to the Moby, even if no, he isn't going to answer Izo's idiotic question.

Which, is actually a fine excuse to extract himself from this situation.

"So, sorry, the response also is personal, hope you don't mind," Thatch nods, and Sabo easily opens the way for him--which, Thatch belatedly realizes, he'd actually been blocking. Scary, little Chief, scary...

"Sorry, didn't mean to pry." Sabo sounds genuinely apologetic, and tips his hat at Thatch as he passes by, and Thatch inwardly heaves a massive sigh of relief. "I'm working on it, but I know I can get a little...pushy, when it comes to things that involve my baby brother."

Thatch continues to walk away.

But inside...

Oh. Yikes, he thinks.

~~

Thatch is in the privacy of the currently empty men's sleeping room beneath the deck, and has just finished writing and giving instructions and bribes to the gull when the hatch creaks open.

"Thatch, we're in trouble," Koala announces as she stomps down the stairs, making her sneaky opening of the door rather pointless.

"I noticed," Thatch says dryly.

Koala pales. "He didn't break any of your toes, did he?!"

"What."

"Well, you're a cook, you make food Luffy likes with your hands," Koala shrugs. "Just wanted to make sure."

"What the fuck."

"I don't think he will! You're Luffy and Ace's crew, and you're a Whitebeard pirate, but..."

Thatch groans. "I already thought your Chief might be trouble, but holy shit I didn't know he was that batshit."

"He might not be!" Koala sounds defensive, but it's not particularly comforting. "He's usually reasonable, kind of, but since his memories came back..."

Thatch throws up his arms. "So, how'd he get it out of you?"

Koala flushes. "I didn't say anything!"

"Sure."

"It's not my fault that Sabo's a damn--!"

There's a loud knock, before the hatch flings open, and Ace pops his head in. "Hey Thatch! What's for snack--"

"NOT AGAIN!" Koala cries.

At the same time, Thatch shouts, "IN A SECOND!"

Either way, the hatch slams shut with a, "SORRY!"

Thatch and Koala stare at each other with their hearts beating uncomfortably rapidly.

They slowly heave a slow sigh of relief as the tension drains.

"I really need to apologize to Ace," Thatch mutters.

"I really need to work on my Observation Haki," Koala groans.

"HEY THATCH, I WANT A SNACK," Luffy shouts, and Thatch and Koala's heads whip around in horror, only to sag with relief at seeing that Luffy's not in the room, but only for a second--

--because after that second, a mermaid's crashing through the hatch, ripping it from its hinges as she slams, hatch and all, into Thatch's chest.

The room fills with dust and debris, and there are shouts outside.

Koala gingerly peers into the wreckage where Thatch is now buried in the wall, a terrified blue gull  perched on her shoulders peering alongside her, its claws digging through the fabric of her shirt.

"We're fine," Thatch coughs, peering down to make sure he'd successfully caught and shielded Luffy from damage, even as he peels himself from the wood. Luffy seems unharmed, though her eyes are wide; she clearly hadn't expected to do quite this much.

"...Armament?" Koala asks, noticing how the back of Thatch's hair is black from where it's fanned around him.

"Armament," Thatch agrees, keeping the entire back of his body coated until he's safely pulled himself and Luffy, still in his arms, away from any sharp wood.

"Sorry, Thatch," Luffy says, not particularly apologetic, if anything sort of curious. She peels herself back from his chest, scritching her cheek while looking down at what was once the hatch to the mens room that had shattered between them. She then reaches back to tug at Thatch's black locks, and oohs when they fade back to auburn.

"No worries, just make sure to make it up to Deuce and Usopp when they have to fix this," Thatch sighs, before grinning, letting his arms fall away from Luffy once he knows she has a secure grip on his shoulders. He then begins carding his fingers through her hair to make sure no splinters got in, and likewise dusting off the front of her vest, taking care not to let his touch linger. Luffy nods frantic agreement, more like rubs her head into his palm, and Thatch feels his heart skip a beat.

Koala sighs.

"Hey Thatch, what's this?"

Thatch blinks, then inwardly curses.

Luffy's holding Izo's crumpled piece of paper. His control of his power's still shoddy, and it must have accidentally spat it back out in the commotion.

Please, don't be able to read that, he prays. He luckily doesn't have much confidence in Luffy's reading abilities.

"It says 'what are her three sizes.' What are those?"

In the background, Koala slowly raises her fist.

~~

A few days later, Marco's scouting when a blue gull rapidly approaches him.

Delivery! it squawks. Delivery for you, Boss, and don't show Izo! Don't show Izo! Don't show Izo or the bread man will be mad!

Thank you, noted, friend, Marco responds, and catches the note from Thatch in mid air.

The gull trills acknowledgement, then wheels away to rejoin its brethren, while Marco changes course for the nearest island, a safe forest haven in Pops's territory, still a ways away from the Moby. It's uninhabited, save for the wildlife, and it would be good to land once before returning home anyway.

Marco lands lightly on the tallest and oldest tree on the island, from where he can survey the island of pure greenery, and the endless blue stretching beyond. The branch he's chosen looks deceptively thin, but he already knows it can support his human weight, which is why he shifts, passing the note from his claw to his hand before completing his transformation.

Marco frowns. The other Commanders (and to be honest, the entire crew) have been acting a bit strange recently, but for Thatch, who isn't even on board with them, to also be in on it...

True, this may or may not be related to that at all. But still.

Marco feels like he's missing something.

Marco, Thatch's message starts, and Marco already knows it's going to be serious because it didn't start with a jibe at his appearance.

Marco, I think I'm actually serious about her. Thoughts, brother?

Her, meaning the Ace's little brother, the mermaid girl.

If Marco remembers correctly, in Thatch's first note back to him, he'd written, She's stolen my heart, I think I want to marry her.

Marco had assumed Thatch was joking at the time, or just light-heartedly flirting, as he always did. Marco's used to hearing Thatch spew these kinds of words, and he'd taken it to mean that the girl's exceptionally Thatch's type, but hadn't thought further.

The words had made him remember a little trinket he'd had stored in a chest at the back of his closet, one he'd received from an elderly couple on Fishman Island around two decades ago...

But that's not important now, Marco thinks, focussing on Thatch's message.

In all his years of flings and casual relationships and jokingly asking ladies (and some gents) Won't you marry me...Thatch has not once asked for Marco's opinion. He's certainly had plenty of opinions himself about whether someone would be a potential good match for Marco, which Marco always ignored. But Thatch has never asked Marco about matches for himself.

Thatch really is serious.

Marco finds himself slowly smiling. "Finally, you sap," he murmurs, though no one hears him but the other birds in the trees around him.

He knows he ought to think more about what to say, but the answer is so obvious that Marco takes Thatch's note, and carefully tears the paper so that his brother's words aren't damaged. Gently tucking Thatch's note into his pocket, Marco pulls out a pen for the remaining small blank strip of paper.

Shortly afterwards, two birds depart from the island, in opposite directions: one, a phoenix, wings burning cyan against the clear skies, and the other, a blue gull headed to Paradise.
