Hiya! I'm Rosie and I play Chara here, as well as an AU version of Batman. (andthebat)

Bruce is probably not going to like Batter very much, due to his No Killing Allowed Ever rule.

Chara, on the other hand, is probably going to be cautiously intrigued if they get wind of Batter's whole "was ordered by a mysterious force to murder goldang everyone" thing because that's suspiciously similar to something they went through recently!
