They don't though. Well, Angie haven't (as we haven't seen Bel interact with the girl again).Father like Daughter both trying to recruiting new family members also still surprised that they ignored the fact the kid killed ppl
Angie specifically wanted to take Char and Byak back to Bordeaux for them to make proper apology of what had transpired (I feel like it shouldn't be just an apology, but well). As of right now, it seems she is very excited to expand the family tree and, just like Bel, she doesn't feel right killing something that shows no resistance (which was Byaku back in ch. 27).
