Kate wakes up in the middle of the jungle, as Jack in 1x01 (and 5x06). She stands up, cleans herself, trying to understand who the hell the others are, yelling Jack's name.
Then, something moves among the trees. She sets her dumb-face, that we know well since season 1. Then a previously unseen blonde man shows up.
Kate: who are you?!
Mystery Man: My name is Aaron.
