I don't think he needed a love interest, but other than that, I agree. He's very childish. The only time he's even a little bit likable is during the homestead missions, and that's mostly because of the other characters, not him.

Does everyone need a love interest nowadays? Can we not have a celibate hero anymore? Yeah, I know he got with some girl at least long enough to make the next ancestor, but still. Does relatability really all hinge on love interests of all things?
