TO THOSE WHO SCREAM 'INCEST'...TAKE A LOOK.
For the last frickin' time. THERE IS NO INCEST IN THIS MOVIE. They have said multiple times throughout the movie that Kovu is NOT Scar's biological son. Kovu and Kiara are NOT cousins.
Don't believe me? Watch the movie again. Even Nuka is saying it! He said, and I quote, "...Scar wasn't even his father. He just took him in."
So there. :-P
