Mouth, Jimmy's mom, and Brooke. Their scenes made me tear up in this episode.
Mouth. That guy was his best friend, and he knew nothing about how he was feeling until the day he saw Jimmy pull out that gun. I felt for him strongly at the time. I can sort of relate to his position, but totally differently.
Jimmy's mom. Fearing her son wasn't going to be okay, but then finding out HE was the one with the gun, HE was the one holding them hostage, and that he killed himself all in one day? She must have felt so guilty and just so.. I cannot put it into words.
Brooke, she had her best friend, her boyfriend, and other friends in that school. She probably felt guilty and so confused. She didn't know what was going on or if the people she loved were safe.
I agree with the two posters who said they felt for Dan. He killed his brother, yeah, but since this episode, and even when he shot Keith, I felt bad for him. He had to live with that, knowing he took that gun, aimed at it his brother, and pulled the trigger in that hall way. And his chances of amending with Lucas, Karen, and Nathan were ruined after that. Yeah, he did ruin them himself, but still. I've always felt bad from him since then.
