Crane: Look, you don't belong here.
Po: I know. I know. You're right. I don't have... I just... My whole life I dreamed of...
Crane: No, I meant you don't belong here. I mean, in this room. This is my room. Property of Crane.
Crane tells Po he does not belong here. He thinks he means with them, but Crane literally means in his room, as it is Crane's.
