Alfred Pennyworth: Were you looking at the old family pictures again?
Batman: At the what? The old family... Oh, yes! I see what you mean. Look at that! The old gang. Yeah. No, I wasn't.
Alfred Pennyworth: I see. Sir, if you don't mind my saying, I'm a little concerned. I've seen you go through similar phases in 2016 and 2012 and 2008 and 2005 and 1997 and 1995 and 1992 and 1989 and that weird one in 1966. Do you want to talk about how you're feeling right now?
Batman: I don't talks about feelings, Alfred. I don't have any, I've never seen one. I'm a night-stalking, crime-fighting vigilante, and a heavy metal rapping machine. I don't feel anything emotionally, except for rage. 24/7, 365, at a million percent. And if you think that there's something behind that, then you're crazy. Good night, Alfred.
Alfred Pennyworth: Sir, it's morning.
The film makes many references to the previous films and TV series as evidence of Batman's desire to be alone, but in the TV show and two of the films Robin has been established as his sidekick already.
