In episode nine, after Kiera and Carlos get taken prisoner by Alec's brother and his friends, Alec brings them a first aid kit.
Kiera: Alec, I don't know how, but you're going to have to help us get out of here.
Alec: I don't know, they're watching me pretty closely. And this door is pretty thin. I'm sure Gates can hear what we're saying right now.
Gates (from the other side of the door): Pretty much.
