[quote="QueenSummer"]But Disney didn't really care. It was all for money. And females are usually smaller ^^ I think Vitani was born in the middle of Scar's reign and Kovu just before Scar died :3[/quote]
No, Kovu and Vitani appear to be the same age and supposedly have the same body mass. Only when lionesses when they are fully grown do they appear to be smaller than male lions, I believe.
[quote="BloodshadeLioness"][quote="TheLionPrince"]If Nuka and Vitani were Scar's cubs, the film would have made mention of it. Plus, neither Nuka nor Vitani refer to Scar as their father so I assume Kovu, Vitani, and Nuka all share the same father.[/quote]
Well, I think Nuka's first line, "Scar wasn't even his father, he just took him in,"
could hint/be a mention of Nuka being Scar's son. It's way too open to interpretation, and I wish they could have given us clear answers as to who was the father of Nuka, Vitani, and Kovu. Oh well, all we can do is speculate

Yeah, I always thought of that as a hint that Nuka may be Scar's son, but I don't think it's enough official evidence. Anyway, from the filmmakers's perspective, they added that line so they can tell the viewers straight on that Scar is not Kovu's father.
