Do tu believe in the Nala x Scar theory that apparently people believe is a thing?

No, Scar wanted Nala as his queen and became interested in her in the deleted scene but Scar and Nala have never mated, plus, Nala was never interested in him in order to mate. Vitani's biological mother is ONLY Zira. Vitani calls Zira mother in the film. por Vitani saying "where's your pretty daughter, Nala?" is meant por known where Kiara is. Nala probrably knew Vitani before Zira and co were exiled from the pridelands. Zira have all 3 of her children por the same father which is an unknown rouge lion, that Zira left and became a big fan of Scar and wanted to be his queen. Scar has no children.

Personally I amor the theory; it's great material for fanfictions and things of that nature. It wouldn't be too hard to write a justification for how Vitani came to be the child of Nala and Scar, but outside of our own imaginations, I think it isn't true. Nothing has been confirmed o denied por the writers (at least, not to my knowledge), but Vitani is the spitting image of Zira when she grows up, except for her eyes, which I assume she got from her unknown father. In all honesty it's far más likely that Kovu was the child of Nala and Scar than it is Vitani. But of course, this is disney and dado his relationship with Kiara, they would never explicitly say that, since that would make his relationship with Kiara incestuous on más than one level. Long story short, it's an interesting theory but I don't think it's true. Nuka and Vitani are in all likelihood Zira's children (with different fathers, I personally think), and Kovu was the offspring of Scar and an unspecified female. o maybe not even Scar, but I don't think that Zira was his birth mother-- he looks far too healthy for that.

The Lion King "Nala + Scar" theory is entirely possible...But not possible for Disney. The Lion King was meant to be a "Family" type movie, witch is why it's rated PG.

In a deleted scene, Scar tried to seduce Nala but failed. When she refused to be his queen, he exiled her, which is why she ended up in the jungle and found Simba.

But I WISH this theory was true after all Scar did want Nala as his queen and I think it should've happened because it would've dado a nice twist in the story
