DOCTOR: So, what are you going to do while I pop over and get her?
TEGAN: You must be kidding, you're not going in there without me.
DOCTOR: I don't want to argue with you Tegan.
TEGAN: Then don't. You can't leave me behind, we're in this together.
DOCTOR: You realise the danger?
TEGAN: Of course I do! And I get why you're worried, okay? But what happened to Adric, isn't going to happen to me.
DOCTOR: You don't know that.
TEGAN: I do know that I'm not staying here while you and Nyssa are in danger. So unless you plan on locking me up-
DOCTOR: Alright, alright.
