Jacob just looked at the other people when they started to argue. He wasn't used to it and probably looked a bit panicky. It seemed that they really were from the same orphanage, but he didn't really get along with anyone there. Some even bullied him for one reason or another, but he never told anyone that though. He didn't like to trouble anyone. And to think that Mysique was so aggressive about this. She actually intimidated even him.
He looked at Bironica and noticed that she actually started crying. He paled when her friends started to come closer, looking quite pissed. He stood up between Mysique and the other group. "C-can we please not fight..." he mumbled nervously. He didn't want to get into a fight on his first day, nor did he want to hurt them. He was pretty sure that they weren't going to listen to him though since Mystique had made her cry and they seemed quite close, so they weren't going to forgive her that easily.
