Gustafson: Look, you're nothing but a Japanese map quest for me so 'till we find that girl just sit there and shut up.
Hiro: I bring Ando from Japan on my mission. I am responsible for him.
Gustafson: All a partner ever does is drag you under or screw you over.
Hiro: A partner helps by believing in you. He keeps you honest!
Gustafsn: Uh-huh. Well who wanted to help the girl? Grab the suitcase? Take your car?
Hiro: (Quietly) Ando...
Gustafson: You take on a partner. All you get is their blood on your hands.
