He really is not sure about the way that Ollie reacted to him. Ollie is like. The one who jokes and mocks him and is a bit of a twit but reliable and Ollie is so damn whole-hearted about everything he does so seeing this... weird dark mirror AU of him is actually incredibly disconcerting.
But he does feel responsible for him, and he's going to look out for him because Ollie is still obviously a bblante and thus needs guidance and the fact that he's... basically a version of Bruce with intense unchecked PTSD (not that Bruce doesn't have it, he just didn't have quite such a severe version of it so young) and that's something he sees as being incredibly dangerous.
ALL IN ALL. HE'S WATCHING. LIKE A WATCHING WATCHER THAT CREEPS IN THE SHADOWS because he's fucking batman.
