autistic coolatta family headcanons with gman being mostly non-expressive and by contrast tommy being super expressive is good

BUT

i like the idea of tommy being super expressive to mask the fact that he by default isn't very expressive, even when he's feeling strong emotions about something, which he often does. this has been misinterpreted enough times as him being uncaring, or apathetic, and at some point he just got tired of it. "performing" emotions for people leaves him tired at best, and terribly overwhelmed at worst- but he's used to it now; and besides, he prefers that over being seen as emotionless and uncaring.

gman's situation is something of an inverse of tommy's. his higherups aren't exactly quiet about the fact that they see feelings as a weakness, and to please them he hides his emotions behind a cool, unfeeling mask. he isn't supposed to feel, but since he can't manage that, at least he can hide what he feels- this is what he tells himself. years of internalizing this sentiment, brushing pent-up emotions under the rug and repressing stims means he now finds it difficult to express the slightest of feelings, even in the safest of environments with the safest of people (of course, only he knows the truth: nowhere and nobody is safe with the employers overseeing everything he does.)
