She shakes her head. Magini won't want to share a bed with her, which hurts, but it would hurt more to call attention to it. 

"No, you two should share the loft; we need you to recover and Keith to be well-rested if he's going to drive" and if you're split up he won't sleep at all. 

"I'll take the floor. I did it all the time growing up." She's stretching the truth here a little, but she doesn't care. She won't sleep any better on the couch, and Magini probably will. 

Nobody objects to this counteroffer. Shiro looks like he wants to, but then (maybe noticing that Keith does in fact look happier with this arrangement) decides better of it. 

"Alright, that works. I suggest we set an alarm for long enough before sunrise that we can eat and be ready to go at first light. ...what time is it, other than the middle of the night?" 

"11:38 pm," she reads off mechanically. (Is Ami giving her the couch as an apology? She... doesn't know how she feels about that, besides vaguely bad).

"I'll set an alarm for 6:30?" It's definitely not enough sleep, but she can't bring herself to care. 

"Sounds good to me." 

...he's used to waking up that early, but he has no idea what time his body clock thinks it is right now. It'll be fine. Probably. 

Keith shrugs and heads up the ladder to get some spare bedding. 

He just about managed to keep to the Garrison's schedule while he was a cadet, but it sucked and he hated it and he stopped bothering to fight his natural semi-nocturnal sleep cycle when he was kicked out. He's been trying to wake up before noon recently so he has more daylight to explore the caves, but "before noon" is a long way from "before sunrise" even in November.

He is not going to be functional at 6:30 AM unless he just stays awake the whole night, which he's seriously considering.

Magini is still avoiding looking at her except for the occasional startled-then-hurt glance when Ami opens her mouth after a period of silence. She hates it, but the least she can do is avoid acknowledging it, and avoid making it worse by staring back.

She wants so desperately to ask Shiro more questions, but that can wait. He might remember more in the morning.

She takes the bedding from Keith with a murmured thanks, and finds herself a place to curl up that's out of sight from the couch.

(It's hard to sleep, especially when Magini's occasional shaky breathes puncture her exhausted thoughts with worry, helplessness, and guilt, but she eventually manages to nod off.)
