I thought when they met for the first time in the movie, it looked personal. There was so much more disdain for each-other than between Zira and Simba. Like there was history. Also I thought it was interesting that Nala knew Vitani's name.
N'awww....they all look so sweet. And this s one of the few pictures I've seen of Zira's age represented correctly, she may be a bit older in t movies but disney producers will maintain that Zira was never the lover of Scar/mate but just an idolizing follower trying to uphold his reign. I really like this.
