oh ye, I forgot about that, Kovu isn't technically Scar's son, just raised to be his successor, so that still works there. Also, he was in the original storyboard meant to be Scar's son, but was scrapped for that reason Cyan said.

But aren't all the lions in the pride related anyways? To my knowledge, in a pride, the main lion mates with all the lionesses, meaning that essentially, Simba and Nala are related as well, so whether or not Kiara is Kovu's niece, they're still closely related. And they're lions anyways, so I don't think that sort of thing really matters that much.
