I remember doing That Bitch on the SE and didn't have any stink bombs, so I can talk with Gary. After the little cutscene I started jumping at him, since on the PS2 version he'd fight almost all the time. But here he ran away and I followed after him. After running around the Girls' Dorm a few times he ran towards the Boys' Dorms, stopping next to the trash bin and I jumped in, so he would stop running, act normal and I could try again. After I got in he ran again and I followed him. He stopped on the side of the male dormitory and I was close enough to hear him. Then he started to cry(like Constantinos or a little kid would) and said something like 'I hate this world!' but I'm not sure. Then I beat him up for not wanting to fight me.
