Beau wasn't awake - she's napping by one of the smaller pools, with the the water at her back. She's used to being woken in the middle of the night, thanks to traveling on the road, but that's usually in a group, with someone on watch. The idea of sleeping by the water was, nobody would get behind her without splashing in the water and waking her up. That way, she couldn't get surrounded by animals without at least a chance of defending herself.

So when Strange's voice comes from very near and behind her, she jolts to a sitting position with her fists up.

"Guh! I'm up, I'm..."

Not in a camp with the rest of the Mighty Nein, being woken by Caleb's prodding and whispering, or anywhere from before it. It's still that cave.

"Aw, shit," she mutters, then twists around to hiss a whisper. "Who was that?"
