Hmm, the review says Worf was sent away by his family to be with humans. I thought he was found by humans, alone, after the desctruction of the outpost by the Romulans. In other words, Worf's family probably thought he was dead. Am I remembering his storyline correctly?
Yeah, Worf was found by Starfleet and was subsequently adopted by humans. Still, I would imagine that Starfleet would have tried to find Worf's family to return him to. It's just one of those things you have to go with.
