Wilf: This Doctor - are you safe with him?
Donna: He’s amazing, Gramps. He’s just… dazzling. And never tell him I said that. But I trust him with my life.
Wilf: Hold up, I thought that was my job!
Donna: You still come first.
Wilf: The thing is, Doctor, that Donna is my only grandchild, you gotta promise me you’re gonna take care of her.
Doctor: She takes care of me!
Wilf: Oh yeah, that’s my Donna.
