Peter does seem to have issues. does sounds like either schizophrenia or drug induced psychosis usually caused by a lack of serotonin in the brain (too much weed and alcohol and other depressants which bring out paranoia and anger. split personality most likely not, more like anti- social disorder or very mild form of autism. He probably stresses over unnecessary things and hides out a lot. Either way if Joe B and Peter B are twins they have done studies in which one twin is certainly more adjusted than the other. Joe B isn't the most approachable type person but prob not as bad as Peter. either way... the shot in the stomach should have been a wakeup call and from what is looks like he doesn't seem to have steady employment. I say the boy needs to pop a few 5 htp, shave his head and spend more time at the gym and do something productive and nice.
