Robin: I’m serving notice.
Red Hood: Of what?
Robin: Day or night, when you least expect it, I’m going to defeat you at something you feel unbeatable at.
Nightwing: You’re going to attack us?
Robin: Yes. Then I’m going to take something personal of yours as a memento and hang it in my room.
Nightwing: And this is to prove what exactly?
Robin: That I am the best Robin, of course.
Red Robin: To who?
Robin: To you. To him. To me.
