He thinks he is useless without his tech, just as much as I think im useless without a talent. He always wants to have the spotlight, but once his thunder is taken from him he goes silent .

He wishes for parental praise, something he never got as a kid sometimes.

He wishes to be worth something , anything else to his brothers.

He doesn't want his anger issues and low empathy issues don't define himself as a bad brother. But he tries hard. Even though they don't see it.
