Really, though. Crane's already heard about this other version of himself - not the one in the city, but the one back in Harley/Bruce's Gotham. He was insecure about him for a time in game; since the two look different, have different problems, different images to project. Also Crane was just massively insecure in general.

If Duo had arrived before I updated Crane to post-rises, he'd be getting more of a reaction, I feel. Crane as he is just doesn't give a shit? The two of them have no personal history save Duo's snooping and behavior WHICH IS REMARKABLY CHILDISH FOR AN OLD MAN so he doesn't... care... so much?
