This fucker
No seriously, this is the one of the only male characters I've seen in any series that's stood out to me as actually being a real living and breathing character.
Damn did I hate this character back in season 1 and I was happy as fuck to see him disappear after like, 2 episodes of his BS, but when he reappeared and got graphed into the main cast, seeing his entire personality change from a manipulating, controlling, absolute degen to the most morale, responsible, socially accepting and encouraging, and overall upright, mature person in the show over the course of about 2 seasons shocked me, and made me gain a huge amount of respect for both the character, and the writers of the show. Not saying this show is anywhere near perfect (especially the disaster of season 4) but this character was, at least in my eyes, was written pretty damn close to what I'd call a "perfect" character arc, going from bottom to top of the social ladder in a way that's elegant, and follows Toms standards of morals. Seeing them change, as events pass, and his world view get molded and shifted in a natural way and follows his train of thought through the experience he gains from both firsthand and secondhand actions.
Amazing character writing overall, and seeing the opposite side of this, Ludo, basically climb the same ladder in this show but going from "pissy boss" to very tactical and fear enducing villan was almost just as exciting to watch.
I just wish the show was nearly as good as I'm making it out be right now lol.
