DOCTOR: It's nice to spend some time together, just the two us, don't you think?

ADRIC: I suppose so... Though, why you'd want to spend any time with me after what happened with the TSS unit, I don't know. You were so angry with me.

DOCTOR: Um, I'm sorry. I know I can be a little hard on you at times, Adric, but I see potential in you, that's all. I would hate for it to go to waste.

ADRIC: Why would it go to waste?

DOCTOR: Because sometimes you're impulsive, and you act before you've fully thought the consequences of things through.

ADRIC: I'm not stupid!

DOCTOR: No! No, you're not.

ADRIC: Then why do you treat me like a child?

DOCTOR: I... I'm afraid of losing you.

ADRIC: You're not going to lose me. I mean, where would I go? You're all I have; you, Tegan and Nyssa.

DOCTOR: I know.

ADRIC: I'm capable of so much more than you think I am. If you'd just give me a chance to prove myself.

DOCTOR: I know, you're extremely capable. One day, you're going to do something great, something very important

ADRIC: Doctor, are you sure you're feeling alright?

DOCTOR: No. No, not really.
