DOCTOR: Never be cruel. Never be cowardly. Hate is always foolish. Love is always wise. Always try to be nice, but never fail to be kind.

DOCTOR: Charley, C'Rizz, Lucie, Tamsin, Molly. Friends, companions I've known, I salute you. And Cass, I apologise. Physician, heal thyself.

DOCTOR: Hello, I'm the Doctor! I believe you want to kill me.

DOCTOR: Ace, give me some of that Nitro Nine that you're not carrying.
