Page "Batman: A Death in the Family" Paragraph 36

* In an issue of Batman & Robin, the Joker begins his murderous attempt once more to another Boy Wonder, Damian Wayne, by trying to win the boy's pity before he attacks him.

However, the Boy Wonder anticipates that the Joker would try to kill him, and the Clown Prince of Crime receives a beating from Damian instead, who also uses a crowbar, mirroring what he did to Jason Todd.
