Inspired by ProfessorSpork's just this heart with much too much to share.
Kristoff wakes to the sound of distinctly male laughter, and before he's opened his eyes, he's imagined fists and icy water and people will beat you and curse you and cheat you
What he sees when he does open them are Eugene and Rapunzel. "Good morning," Rapunzel whispers to him, giggling before leaning over and—
He still has no idea what's going on, but moans into the kiss anyway because wow, good morning is right.
"Kristoff?" asks a sleepy voice from his—lap? He looks down to meet Anna's eyes. "Wha' happened?"
He frowns, looking around; they're on the massive sofa in Anna's room, there are overturned bottles on the floor, some clothes…
Oh.
"Not my tiara," mutters someone leaning against his shoulder—wait, what?
"Oh my gosh, that's so cute," Rapunzel gushes, beaming. "Elsa talks in her sleep!"
"Yeah, I guess," Anna says, but Kristoff's still stuck on the fact that Elsa's, you know, here when last night they probably—
The important thing, he thinks, is not to look terrified.
"Threw that 'way," Elsa mumbles, apparently still asleep, "G'ask Marshmallow."
"She used to, back when we slept in the same room?" Anna says, answering the question no one asked. "I didn't know she still."
Eugene chooses to swoop in that second, running a hand up Anna's thigh and doing this over the top Flynn Rider eyebrow thing that makes her laugh and makes Kristoff want to roll his eyes and join in at the same time, except that his mind is now plowing onto even scarier scenarios, because Elsa doesn't even like men, so what—
But bits and pieces of last night are finally starting to float in: music, and laughter, and Elsa drinking them all under the table, and…
"We just talked," he says, feeling stupidly proud. And—relieved, obviously. "We stayed up talking."
"We know, we were there," Eugene snorts, and reaches out to tickle his chin.
Kristoff makes a half-hearted move to bat him away, but doesn't get very far because…well, Elsa's still sleeping on his shoulder, and he doesn't want Anna to fall off his lap. "How come you guys woke up so cheerful?"
Rapunzel giggles again, snuggling into his other side with Eugene. "We never slept."
"You can have my orb," Elsa mumbles.
"Oh, good," Kristoff says. He leans back again, feeling the warmth of everyone around him, and idly tangles his hand in Anna's hair.
It's a very long time before any of them tries to move again.
