DOCTOR: You know Tegan, sometimes I wonder how well I'd get along without you.

TEGAN: Thank you.

DOCTOR: Probably quite alright, all things considered. Now, a fresh cup of tea would be terribly useful.

TEGAN: Yeah? Well, you know where the kitchen is.

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.

RUATH: I'm so glad you remember me Doctor.

DOCTOR: Ruath! How could I possibly forget you?

RUATH: 700 years is an awfully long time. I see you're on your fifth body already, very careless of you.

DOCTOR: The universe is rather more dangerous than Gallifrey.

DOCTOR: Tegan, sometimes I wonder how well I'd get on without you

TEGAN: Thank You

DOCTOR: Probably quite alright, all things considered
