I mean yeah I didn't actually think Damian would actually believe Anya that easily but man it would have been so funny.

But also it's gonna be hilarious later in their lives when Damian realizes Anya CAN in fact read minds and kicking himself over the fact that she told him when he was FREAKING 6 YEARS OLD and he didn't believe her. Clearly Endo is thinking foreward into the future I see his game I get him.
