Well, there are some rumors that she was the lioness who said "My, how you've grown," which I personally don't believe to be true. So, nope, I don't think she appears in TLK2, unfortunately
Oh, and I love Sarafina! She's by far the most beautiful one to me, she just seems really elegant and lady-like. I somehow wish she appeared more in the movie, she definitely deserved more than one whole sentence.
