Spoilers 5x19, based off the press release and the stills we got for that episode, as well a post by ohpineapples on Tumblr.
She's the first thing he lays his eyes on when he enters the bar, like a beacon of light in the middle of the pretty dark room, in contrast with the sun still shining outside.
When the last clue the scavenger hunt Charles organised for his bachelor party lead him and the rest of his male friends to Shaw's, Jake first thought he had been wrong somewhere, and missed something. After all, this was where Amy was having her own bachelorette party with the ladies of the Nine-Nine and her best friend Kylie.
So why would they end up there too when the room was already occupied – by his fiancée, of all people?
Wasn't the whole point of bachelor/ette parties to have the future groom and bride have one last celebration without their other half?
(Not that Jake would mind sharing his with her, though. It's always more fun, when Amy's by his side and enjoying a party with him and the rest of their friends.)
But then he turned to the older detective, and he saw the big, bright smile on his face, barely able to contain his excitation as he was waiting for his reaction to come, and he finally understood.
This was the man's plan all along – to reunite the two lovers at the end of the game for a night of celebrating all together.
Jake smiled back at his best man – best friend –, moved by the lovely thought. No doubt, he had always known how to make him happy.
He didn't waste any more second and pushed the door that separated him from the love of his life, soon followed by the others, and was met with the sight of Amy in the middle of a cheering, very drunk crowd. All of this happened a few seconds ago, and he hasn't moved since, stuck in his admiration of the woman in front of him.
She, on the other hand, hasn't seen nor heard him arrive yet. She's too busy and concentrated in whatever game she's playing right now to notice anything else happening around her.
(She's probably winning, judging by the way she raises her hands and makes loud noises of victory.)
His fiancé lets out an amused chuckle watching her, before someone comes and takes him out of his contemplation, patting him on the shoulder. He quickly, reluctantly turns his gaze away from her to see who it is who joined him, and sees Charles standing by his side with a grin.
"Congrats bach boy, you found your treasure!" he happily tells him, pointing to the woman he was staring at until then. Jake silently puts his whole attention back on her, not bothering saying anything back, his friend's words repeating themselves in his mind. You found your treasure.
And he did indeed, about three years ago, when they finally got together after all this time pining for her. There's no doubt in his mind – she is his treasure.
The most precious thing in his entire life.
"Thanks bud," he eventually tells the other man with a grateful smile, who simply nods in return, glad Jake liked his idea after all, despite the rough start his scavenger hunt got.
It takes Amy some more time to notice that Jake is here, but when she does, she calls his name before abandoning everyone and clumsily reaching to him with a grin lighting her features, soon matched by one of his own. She greets him with a kiss, and his hands naturally find their place at her waist, holding her close.
(And steady – it seems like she's had so much to drink, she can't stand straight anymore.)
"What are you doing here?" she asks, curious, when they part. "You guys still struggling with your scavenger hunt? I'd love to help, but you should know I've had a few drinks already so I might not be able to think properly anymore…" she warns him, letting out a small sheepish giggle as she confesses.
"Only a few?" Jake teases her, feeling how hard she holds onto him to keep her balance right now. She pouts, feigning being offended, and it only makes him laugh more.
She's adorable, he can't help but think.
He soon falls serious again, though. "Don't worry, we don't need your help. We figured everything out already."
Despite what she just told him, Amy seems a bit disappointed by her fiancé's answer. She loves those kind of games, after all – even when her mind is so blurry.
"And what was the price?" she still wants to know.
Jake pauses a second to look at her, his eyes full of love for the woman between his arms, and his grin only grows wider when he lets out, "You."
Amy's face instantly softens, and she's unable to make another sound, melting inside.
For a short moment they remain quiet, simply taking in the other, until the male detective sees it – a bandage on top of his fiancée's head. He reaches to it with his hand, gently brushing it with his thumb, and a worried frown appears on his features as he does so.
"What happened to you?"
"Nothing," the woman quickly reassures him, taking his hand off her and squeezing it in her own. "I slipped and fell down the bar while spraying everyone's face with alcohol. No big deal." She shrugs nonchalantly, and this explanation immediately calms Jake down, even laughing at the image forming in his head.
"Seems like you're having a great time," he eventually tells her, and she acknowledges his word with a nod.
"I am. But the real party starts now that you're here. Let's grab you a drink."
She leads him towards the bar without waiting for an answer. They stay there for a while, sharing a beer and stories about their day and what their friends organised for them in animated conversations. But then Jake seems to suddenly remember something, and he falls silent, scanning the crowd around them as if searching for someone.
Then he turns back to Amy, who's watching him in confusion. "So, which one is it?" he asks with an amused smile, and it takes her some time to understand what he means.
Oh right, it finally hits her. She did tell him about one of the members of the band they hired for their wedding also being a guy she formerly had sex with, while they exchanged a few texts during the day – mostly drunk declarations of love, or Jake asking her for help when his clues started getting too tricky.
And that, too.
Discreetly, she points to a man standing not so far away from them. "This one."
"Ooooh, nice, Santiago!" Jake can't help but tease her when his eyes find the very handsome man she shows him, humming in appreciation.
Her response his quick to come, punching him in the sides, apparently not amused. "This is not funny!" she complains, but her reaction only makes her fiancé laugh more.
She rolls her eyes, exasperated and ready to snap back, when they're suddenly interrupted by Charles and Rosa calling them to join in a game they just finished preparing for them.
They oblige then, and soon men and women find themselves in a fight for victory led by both members of the couple of the night. Needless to say things escalade rather quickly, with those two very competitive people at the head of their respective team. But, even though the scores are tight all game long, the ladies are eventually declared winners.
Amy can't help but make a whole fuss about it, teasing Jake about his loss repeatedly, but for once he doesn't care, because she's too damn adorable right now to feel disappointed.
She looks so happy – that's really all that matters to him. He would lose every game he'd ever play if it meant seeing her smile never fade away.
Someone else doesn't agree with him though, and it does bother him that the women won. Indeed, Captain Holt immediately asks for a return match, claiming his team was disadvantaged by having Hitchcock and Scully being part of it, and asking for a share fair of people, when they were the ones outnumbering their adversaries in the first place.
No-one complains then when the ladies accept his request and their boss excludes the two detectives from the game – not even the concerned parties, who oblige without question, too happy to be able to go back and sit at their table to watch the others play from afar, not understanding the rules anyway.
It's only much later in the night, when the bar has started to empty and people to calm down, tiredness taking over as alcohol is slowly leaving their bodies, that Jake and Amy find themselves alone together again. Seeing him at the bar ordering one last beer, the newly-graded sergeant stands from her booth where Rosa and Gina are half-asleep next to her, and walks towards Jake.
He smiles as he sees her approaching and the minute she's by his side, he gently grabs her by the waist to pull her close to his chest.
"You alright?" he softly asks her, and she simply nods and hums in return, smiling back at him before she puts a hand around his neck and leans over in a tender kiss.
When they eventually part, they stay still, keeping their eyes closed and tight embrace, foreheads resting against one another.
"I can't believe we're getting married in less than a month already," Jake whispers, breaking the silence that fell around them.
"Twenty-two days," Amy specifies in a same soft voice – of course she's counting down the days –, and her heart misses a beat at the thought. "We're getting married in twenty-two days."
They still have a lot to do before the D-Day for it to be completely perfect, and it will probably freak her out later when she realises how little time they have left to organise it all, but for now she doesn't care – she simply relishes that tender moment she's sharing with her future husband.
