[quote="Tavrida"]I don`t think that it was Scar`s pride. 1) Zira saw "I have been exiled, left ALONE with no defense. 2) All the lionesses in TLK was against Scar. Maybe there was one-two lionesses on Scar`s side, but not 15-16.
In my opinion, Zira created her own pride after Simba exiled her.[/quote]

I like this theory. Scar wouldn't have wanted another pride anyway. Remember his reaction to Sarabi's "we must leave Pride Rock" suggestion? The Pridelands must have some meaning to him. I don't think I've come across a Taka fanfiction that directly addressed the significance the place had to him.
Now that I'm thinking about it, her recruiting of the Outlanders would have been a great scene/flashback. I really like the sequel, but with all the great ideas floating around the internet it makes me realize how bland the movie is.
