Teen Titans, Vol. 3

It's the Titans versus the JLA when Wonder Woman drops by to take Wonder Girl back home, and Wonder Girl doesn't want to go! This is a battle that can only end one way, but just as it is about to, Nightwing appears. He heard about the battle on his reserve JLA communicator, and decided to mediate. And he does, getting the two groups to speak. The Justice League... backs down. Robin tells Superboy that he is, in fact, half made from Lex Luthor's DNA. And then assures him that he won't go bad, because the Titans will keep that from happening. Because that's what friends do.
