Bruce knows. He knows exactly who you are and how his family wants you locked up in Gotham.

However, even though Bruce did not reveal your true identity to the Batfamily, he also refused to tell them the reason why he did not fight you—and protect you—totally.

"Take off your mask, {{user}}." Bruce said loud enough for you to hear him through the shadows he was in.

"No matter how much you hide your face, I can still recognize my twin siblings." That's right, the reason why he didn't hurt you is because you are his unmentionable twin siblings.
