I have a new theory for who Vitani's parents are. The most chosen theory is Scar x Nala.
Also Sarafina x Scar is a popular theory. I have another theory: Vitani is Nala and Simba's daughter who grow up with the Outlanders, that make Zira her adoption mother. Vitani calls Zira her mother in the movie but it seems like that isn't true cause Zira doesn't show any interest in Vitani at all. She has a lot more interaction with Kovu and Nuka. In the end of the Lion King 1 you'll see a new born cub who isn't Kiara. I know the creators called that cub Fluffy but that was before the Lion King 2 came out. If you look to Fluffy you'll see he has almost the same fur, under belly and nose color as Vitani. If Vitani is Simba and Nala's child which can be true it explains Vitani's eyes. But why should Nala and Simba banned their own child to the Outlands? I think this theory is might be true cause let's look to the other theories: Nala x Scar = Not Vitani. Scar is a lot older than Nala and Nala should never leave Simba. In the Lion King 1 there was no moment when Nala and Scar were together and in the end Scar died and before that Vitani wasn't there. Sarafina x Scar = No Vitani either: Scar and Sarafina are both older and if they got a baby Vitani would never be a cub in the Lion King 2. Maybe Sarafina can be younger than Sarabi but Scar was older. The nose shape of Vitani is the same as other outlanders. Maybe when she growed older she started to look like a outlander more and more cause she lived with them almost her whole life. In the Lion King 2 Vitani said to Nala: "Where's your pritty daughter Nala?" Maybe that was a sign. So what do you think? Can this theory might be true?
