SPOILERS 5x18. Canon-divergence, in which Jake and Charles come back to the precinct while Amy is still there in her wedding dress.
"And I want a mermaid cut with tulip sleeves."
"Say it again. Say it loud."
"A mermaid cut with tulip freakin' slee–"
Amy is cut short in her demands for her perfect wedding dress the second she turns away from Rosa to face the rest of the people in the bullpen, and watches helplessly as the elevator's doors open, revealing to her sight Charles, then another guy, and then Jake as they walk out of it in the middle of her shooting the last word.
The older detective is the first one of the two to notice her, with her fiancé being too caught up in whatever he's doing on his phone to look up yet. But then Charles lets out a choked gasp as soon as his eyes lay on her, and it's all it takes for the younger man's attention to finally been drawn to what's happening in the room, curious.
He spots her right away. Which isn't a surprise really, given how the whiteness of her dress contrasts with everyone else's outfits around her (everyone except for Rosa, maybe).
His reaction is quick to come then – his hand falls back to his side on its own choice, and he freezes, mouth half-open and curling up in a puzzled yet dreaming smile, staring intently in her direction, unable to take his gaze off her even for a split instant. The look in his eyes is indescribable, but there's so much love and awe in it, Amy can feel it piercing through her whole soul and warming it all up along the way.
(Her cheeks turn a little shade of red too.)
The room fills with silence, or maybe that's just them being too caught up in each other to notice anything else, but a moment passes and they simply remain like this.
There's something about seeing her in a wedding dress that suddenly makes it all the more real to Jake, that they'll soon be united, and that's silly because he knows it's coming up, they've been talking about it for months and even more so now that the ceremony is nearing and they still have so much to take care of, but still it seems like there's a whole world between mentioning it and actually seeing it taking some kind of form for the first time. And clearly, he wasn't prepared for what looking at his fiancée in that pure, white gown would to do his heart.
He's dreamed of that moment so many times – and now it's really happening. He's literally on the verge of breaking into tears – blissful tears, of course – when he thinks about how this is his life right now, and how in about a month she's going to marry him.
That she's going to be standing there in her wonderful gown and slowly come to him.
To think that just a year before he was being sent to jail, thrown to an uncertain future that could have cost him up to 15 years away from the love of his life.
Thankfully it didn't come to this. Thankfully now his future is clearer than it has ever been – he's gonna spend it by her side. And nothing could make him happier than that.
As all these thoughts wander in his mind, he can't manage to turn his eyes away from Amy, no matter how hard Charles tries to make him look away, even using their perp as a shield between the two lovers to block his sight because what the hell Amy, do you want your wedding to be doomed?! He can't see you like that!
But the truth is, right now, Jake couldn't care less about those dumb superstitions. Not when his fiancée in standing right in front of him and looking so damn gorgeous.
"Calm down, Charles!" she finally speaks up, tired of their friend's whining. "These are just superstitions, and it's not the dress I'm going to wear to my wedding anyway."
"It's not?" Jake raises a confused eyebrow at her words, suddenly finding his voice again, surprised. She gives him her whole attention again then, and her features instantly soften the instant their gaze meet. She offers him a small, loving smile as she finally makes a step forward and approaches him.
She puts both her hands on his arms when she reaches his side, gently stroking them while she explains herself. "It's not really my type. I was thinking about… something different." She doesn't want to go too deep into the details with him – wants it to be a surprise.
"Whatever pleases you." Her fiancé simply beams at her as an answer before stepping closer, pressing a soft kiss on her lips. "But for the record, you look stunning in that dress."
(He'll learn a month later that this first peek at Amy in a wedding dress did nothing to his heart in comparison with seeing her in her new one – her true, chosen one – walking down the aisle with her bouquet of flowers wrapped in New York Time's paper from April 28th, 2017 to join him in front of the precinct.
There are tears prickling in his eyes when he breathlessly tells her as she's finally reached his side and before anyone else starts speaking, only for her to hear while he squeezes their fingers together, never once looking away from her even just for a second, "You look like a mermaid in that dress.")
(He'll learn later as he takes all his damn, sweet time to take it off her on their first night as a married couple, not wanting to crumple it on his way, that it was made on purpose – that such a thing as 'mermaid cut' does exist and that it was exactly what Amy was looking for.)
