Poison wakes kind of faster than he usually does, because Jack's voice sounds weird, and in his general state of low-key paranoia, he notices stuff like that. Also... he just-- he feels different? He moves a little, sleepy brain trying to wake up faster as the not quite right sensory input starts gaining traction.

He slides his hand up Jack's back and... okay there's a lot more hair than he's used to. It's longer.

"Jack?"
