Upon rewatch, I think the tragedy of Five's character is actually done somewhat decently in s4.

Upon rewatch, I actually felt so deeply for Five. It is so sad to hear Lila say he was just a distraction. Imagine hearing that when all you wanted your whole life was to appreciated and cared for, but you were deprived of it for 70 years. Seeing how head over heels he falls over Lila actually makes me sad, with the interpretation that he doesn't actually love her like that, but the idea of her. The same way he loved Dolores. It seems more like at trauma response than out of true love. Which is just so sad to think about; he never could feel love for someone who didn't go through such immense trauma because he grew up in the wastelands of the apocalypse—that is what is familiar to him. Anything else felt off to him. Imagine living 40 years in a barren wasteland with NO people and what that does to you. There is no way Five would be as stable as some of yall thought him to be in s1-s3. He was constantly unraveling, growing more and more exhausted and still being dismissed by his family. He deeply desired some sort of intimate love, a life partner, someone who would choose him every time the way he would for them. It makes sense why he did what he did.

Idk I know that likely isn't what the writers intended but it makes me so sad to think of it in a tragic sense.
