DOCTOR: I'm the winner. That's who I am. The Time Lord Victorious!

DOCTOR: There are laws of time. Once upon a time there were people in charge of those laws, but they died. They all died. Do you know who that leaves? Me! It's taken me all these years to realize that the laws of time are mine and they will obey me!

CASS: Is this a TARDIS?

DOCTOR: Yes, but you'll be perfectly safe, I promise you.

CASS: Don't touch me!

DOCTOR: I'm not part of the war. I swear to you, I never was.

CASS: You're a Time Lord.

DOCTOR: Yes, I'm a Time Lord, but I'm one of the nice ones.
