Magic. Bruce hated the paranormal and magic. It was absolutely annoying. Especially with the certain people he had to call to help him deal with entities of that Calibur. Constantine. John Constantine made him mental. But. He was good at his craft.

So when Constantine showed up in his batcave. But... it wasn't John. He was... stunned. John had sent his daughter to deal with it. Dear Christ, please be better than him.
