fishy's babs that she's really kind to
joseph - suffers from gift-associated depression and post-traumatic stress disorder
anthony - lost his father at a young age to the vietnam war
peter - overly critical of his performance due to strict, emotionally abusive parents
roderick - suffers from catatonic schizophrenia and acid addiction
the other three are, for the most part, fine. noah's got shitty parents, but it doesn't really affect him on a day-to-day basis.
