"I don't know. I've been off all day. My reflexes aren't what they'd normally. My clothes don't fit right. It sort of feels like I grew an inch and added pounds while I was sleeping...." Selina sounds a little concerned by it but not in a way that would cause her to panic too much. She makes her way to the sales counter and takes a closed bottle of water from the clerk there and comes back with it, handing it to Emma.

No, she doesn't care that the sales clerk seems upset by this nor by the fact that she just stole a bottle of water.
