As the sun awakes Amy from her slumber the following morning, she can't help the smile that emerges when she finds Jake sleeping next to her, holding her and running his hand up and down her side. He looks so young and vulnerable as he lies there. She reaches up to tangle her fingers in his curls but is stopped when his hand meets hers and he brings her hand to his lips and kisses it softly. "Morning," he grumbles as he pulls Amy closer towards him with his other arm. She can't help but giggle as he peppers kisses all over her face and neck, feeling like a teenager again. With one smooth move, he takes her lips in his and lingers for what seems like forever.

When air becomes necessary, they separate and stare into each other's eyes for a few seconds. Amy disturbs the silence by saying, "Mmmh, someone's in a good mood this morning."

"How can I not be, when I've woken up with the most beautiful woman in the world? God, I have wanted to say that for so long… didn't think it was appropriate given our past," Jake replies with a smirk on his face. Amy can't help but blush and drops her head to his chest in embarrassment. He drops a kiss to her hair and continues, "I can't wait to spend the day sat across from my girlfriend." He freezes, and she looks up at him, a smile from ear to ear. "I mean…" he stutters. Before he can continue, it's Amy's turn to initiate the kiss. She puts a hand on his cheek and kisses him deeply before saying, "It's fine, Jake. Well, only if I can call you my boyfriend?" Both of them burst out laughing. It's so cheesy and embarrassing but neither of them cares – they are in a total state of euphoria. They couldn't be happier. They spend a few more minutes lying there in each other's arms before deciding they actually need to get up if they were going to get to work on time, and discuss how they are going to play this.

They arrive at work separately. They both feel they need some time before they tell the squad their big news. So, as per the plan, Amy arrives 15 minutes early, like she always does, in her own car and Jake would arrive on time in his car. The plan was fool proof; or so they thought.

Everything was going perfectly until Gina once again got involved. She'd been studying Jake and Amy's behaviour all morning. Something had changed, and she was going to get to the bottom of it. If either Jake or Amy paid any attention to their surroundings, they would have noticed that Gina had not touched her phone for over 5 minutes, something extremely out of character. But instead, they were too caught up staring at each other and offering each other small smiles. You could tell they were trying to be discreet, but it wasn't working well, especially when there are people watching your every move.

Gina went back to looking at her phone, trying not to arouse suspicion herself, when she hears Amy get up from her chair and start heading to the evidence lock-up. She watches Jake closely. As she suspected, he can't take his eyes off of Amy until she out of sight, which is when he turns back to his computer and pretends to look interested in whatever is on the screen. That's when Gina can't help but step in. She quickly fires off a text to Jake:

Gina: Somethings happened hasn't it

Jake: I don't know what you're talking about

Gina: Don't play stupid with me lover boy. You forget I've known you practically all your life. I can read you like an open book. Now spill…

Jake: Okay, fine. Me and Amy are… kind of… sort off… together

Gina: And Gina strikes again

She quickly screenshots it and sends it to the others with the caption: "Stage three complete." It just so happens that Amy is walking back into the bullpen as the others receive the news from Gina. Charles lets out a scream which confuses Jake and Amy but receives laughs from the others.

Rosa looks back and forth between the two detectives and says, "You two finally boned then. Congrats," with that signature smirk on her face. Amy immediately looks horrified and her eyes widen as she turns to look at Jake.

"Jake… what's going on?" Amy's confused as Jake pieces together what must have happened. He turns towards Gina. Gina tilts her head to the side and smiles. "Sorry, not sorry," she says as she tries to contain her laughter. Charles, meanwhile, is still trying to come to terms with what's going on. It looks like he's hyperventilating – nobody's too worried, though. Classic Charles!

Without another thought, Jake looks towards Amy, her confusion only growing when he mouths "Forgive me." He stands up, and within seconds, he's placing one hand on her waist and the other comes up to rest on her cheek. Before she even has time to comprehend what he's doing, Jake leans down and takes her lips in his. An applause - and a further scream from Charles' direction, followed by a bang as he hits the floor from fainting - rings round the bullpen as Amy brings her hands up to Jake's shoulders and returns the kiss.

What nobody realises is that Captain Holt is now standing by his door, coming out to see what all the commotion was about. The corner of his mouth curls slightly upwards when he finds the answer. It was one of those smiles that if you blink, you'd miss it. But it was definitely there. Holt clears his throat, just loud enough for people to hear it. Jake and Amy part, ducking their heads in embarrassment, but staying in each other's arms. Before anybody could explain, Holt says, "I expect the paperwork on my desk by the end of the day," and with that, he turns and walks back into his office. Jake and Amy turn to each other, blinding smiles plastered on both of their faces while the others head towards them to congratulate them individually.

Gina can't help but say to Jake: "And that my friend, is stage 3 of Mission: Peraltiago! You did it! I won't go as far as proud, but I am genuinely impressed." He smiles at her. He can't help but wonder if they ever would have got to this point on their own. Either way, they are both incredibly happy.

Mission: Peraltiago – Complete!
