Henry Van Statten: We're hidden away with the most valuable collection of extraterrestrial artifacts in the world and you just stumbled in by mistake?

Henry Van Statten: Question is, how did you get in? Fifty-three floors down, with your little cat-burglar accomplice. Quite a collector yourself. She's rather pretty.
Rose: She's gonna smack you if you keep calling her 'she'.
