I can’t remember any other examples off the top of my head, but I just rewatched the one where Alexander gets dropped off into the enterprise by the grandparents. And I just feel so bad for this kid. In the episode with his mom, they clearly have a really strong bond. She loves him, he loves her. Then she does, worf basically says “look at her body! Look at her death!..btw, I’m your father” And then ships him off to a planet he’s never been to, to live with people he’s never met. Then those people, the only familial connection he has had since his mother’s death, decide they just straight up don’t want him anymore. He dad throws a tantrum in front him because he damn sure doesn’t want the kid. Begrudgingly agrees to keep him, and when the kid makes a mistake and acts out, he’s told he’s going to be sent to live with Klingons. Given his mother’s politics, probably something that scares the shit out of him.

And that’s just in his first 2 appearances. That poor fucking child.
