How do আপনি think is Nala's and Vitani's relationship after the events of Simba's Pride?

I'm sure they apologized and became good friends, since now Vitani is part of the pridelanders.

It's hard to say. They were probably neutral between each other. Like, I just kicked your butt but we're good right? No XD they probably became good বন্ধু for all we know.
