Batman: Concentrate, Lantern! The things you make with that ring are breaking apart. That means your mind is scattered, right? You need to calm down and —
Green Lantern: I am calm, Batman. I’m always calm.
Batman: That’s not what it looks like.
Green Lantern: Hey, worry about yourself. You’re the one without powers.
Flash: Batman doesn’t have powers? — I thought you were a vampire or something.
