Where do you want me to start?

I'll go with Sasha's dream episode. Rizzles stuck someplace together (in winter) au!

you would lol 

"I’m cold."

Hours slowly passed in the cramped confines of their seats, but they’re too close to the perp’s location to chance him hearing their running car. Instead, they started the night with quiet conversations about work and Maura’s favorite recipes, a game of rock-paper-scissors about whom would get the only pair of gloves, and Maura using the dashboard for her to-do list made of sticky notes. 

However, things got really boring, really quickly, leaving Jane to see how many time she could pop her chewing gum before Maura popped, and Maura wondering why she voluntarily offered to do this. 

Managing to twist around in her many layers, Jane pulls off one of the blankets wrapped around her and tosses it to Maura in the passenger seat.

Maura smiles in response as she adds it to her collection of layers (which may or may not be already five times more coverage than Jane has), and burrows down further in her seat. 

Looking to Jane’s profile, barely outlined by the little moon light filtering in through the clouds, Maura wants nothing more than to take her tired friend/lover/something indefinitely more home—either of their homes, because as long as she’s next to Maura, it doesn’t matter if the mattress is slightly less than luxurious—and let her get the sleep she so rightfully deserves.

Instead, she pulls one of the earbuds from her ear and holds it out to Jane. 

Jane smirks. “Yo-Yo Ma?”

"I told you I don’t listen to Yo-Yo Ma," Maura refutes, though her lips turn up ever so slightly. "In public." 

"Your secret’s safe with me," Jane replies. She reaches out to take the earbud, but then hesitate as she looks out the windshield before back to Maura. "I shouldn’t." 

"I understand." Pulling out both earpieces and dropping them into the cup holder, Maura turns in her seat so that she’s facing Jane completely. "Do you really think he’s guilty?"

Jane sighs. “I don’t know.” 

"Then why are we here?"

"I don’t know." Jane drops her head back against the headrest and pinches the bridge of her nose. "This case is shit. For the first time, I…I really think I’m in over my head here."

Silence envelops them for long moments. Realizing Jane isn’t going to brush the admission off like she usually does, Maura reaches out and squeezes Jane’s bare hand in her own. “You’ll figure it out, Jane. You always do.” 

"You do until you don’t," Jane replies, wryly smiling.

Jane finally manages to open her eyes and turn to face the other woman. Golden strands of hair stick out from under a knitted winter hat that’s haphazardly pulled onto her head, faint circles are beginning to form under her eyes, and her chin trembles as she tries to fight off another shiver.

In other words, she’s really damn adorable and only made even more adorable by the fact that she’s here, voluntarily, at four in the morning, freezing her ass off just because she wants to be. Just because she loves Jane as much as Jane loves her. 

Jane gives the smaller hand in hers a slight squeeze before releasing it, though she really wants to do so much more. There’s a time and place for that, though, and a undercover stakeout really isn’t it. 

Instead, she asks, “Whaddya say we crack into those donuts?”

"Do you know how much sugar are in those?"

Twisting in her seat, Jane grabs the box of donuts from the backseat and plops them in her lap. When she opens it, the sent of sugar and sinfully sweet goodness fills the car. She picks up the lone donut in the middle, Maura’s favorite kind, and brings it up mere inches from her face. “I guess that just means I get this chocolate-covered sprinkled one all to myself—”

Maura instantly leans over the center console and attempts to get it from Jane’s taunting, flailing grasp. “I didn’t—Jane Rizzoli!—I did not say that.”

Finally winning it back, Maura bites into it, leaving remnants of chocolate in the corners of her grinning mouth. 

There’s a time and a place for girlfriend things and work things, and Jane knows, without a doubt, which one this is.

She doesn’t hesitate to lean forward and press her lips against Maura’s own, briefly, but long enough to feel their softness and warmth and familiarity that’s somehow newer, different each and every time they kiss. 

Jane pulls back, smiling as she recognizes the slightly stunned, but most definitely pleased look on Maura’s face.

But what can she say?

Maura flavored chocolate has always been her favorite.
