this is probably how the bat villains react to hearing who's gotten their ass in jail when they're outside, either "Ah well" or "good i hate that guy" i doubt unless they have some need for each other that they really care that much and will probably just catch up when they're in arkham with them ^^
eddie most likely keeps up with whos where, the info bug he is.
I wanted to sketch Jon and Eddie in what they might wear in their down time. with jon for some reason the brown jacket with elbow patches says "Professor" to me, and i gave him a turtle neck because xmen first class gave me a total fetish for them. Eddie i figure would have to be talked out of just wearing his suite everywhere is i made his very similar to his costume. i wanted to do him in a vest but i thought it might look strange with jon dressing so much warmer then him if they're next to each other. god knows what horrible things are in jon's briefcase.
They're prolly shopping for essentials, food, books, experimental chemicals, that sort of thing
scarecrow and riddler are from batman and belong to DC comics
