This is absolutely not a diss on anyone who did like the Collector's ending there's merits to it and interpretations that make it more reasonable but sometimes idk it's such a let down when you're watching a show about found family, acceptance, healing from abuse, etc and you get attached to this character only to never see them get more than a gentle dismissal.

I have to wonder what kids who are more like the Collector than the other kids in the show or who have similar behaviors because of neglect feel about that ending. Maybe for some of them the idea of leaving everyone behind to be in their own space would be freeing and exciting but it does come with the implication that the Collector didn't deserve to have a real family.

That's what stings about it I think, I know that wasn't the intention but his resolution really kinda was like "ok now take this and go away" in the end he was too out of touch, too powerful, too weird, too messed up, and no one especially wanted him enough for the writers to justify him staying.
