The glance she casts back at the hallway is a little theatrical, like she's expecting orderlies to swarm out of the goddamn walls hoping to catch her doing something illicit and ready to drag her back to her room for fraternising with the other patients like she's expressly forbidden not to by those rules they'd read to her on Day 1, and she ducks in quickly afterwards, nudges the door shut with her foot.
Dean's note gets a laugh - mysterious coffee spirit, eh? She figures could get used to the title - and an obviously-fake frown and pout as she raises the hand not holding her own coffee in a gesture of surrender. "And I would have gotten away with it too if it weren't for those meddling kids... no problem-o" She grins again, flicks her hair back from her face in what she hopes is a suitably casual manner (she's getting better at this 'acting normal around Dean' thing, right?). "Why, who else did you think it'd be? Partners in crime, right?"
Jo clinks her cup against his like she's proposing a toast, careful not to spill the coffee, before taking a swig. It's hot, and it's caffeinated, and it's a damn sight better than the crap they serve here, and sure, one day Weetzie'll get another prize inmate and forget about Jo, or else someone'll step in and tell her it's inappropriate to buy the crazies coffee in the morning, but while it lasts she's going to make the most of it.
