I suppose a few of us like Vitani due to many things. Some like her as an adult, others prefer as a cubby and others just go with personality. My preference though, I like Vitani when she's older. Near the end of TLKIISP, you can tell she saw more of the bright side of things since her heart has opened up. ^^ She may appear like a killer to some lions but deep down, you can have a sense that Vitani is a gentle lioness.
Those are my thoughts though lol.
