I really like Lisa, I think she's a class act. She's shown empathy, humour, sensitivity, compassion, fun, guts and determination and with a fraction of the screen time of other camp mates. As someone above described her, she's the 'slow burner' and I think if she can survive the first two or three evictions she could end up going far. Other celebs have been fairly low in the votes at the start and built up support along the way and I think when the camp thins out Lisa could really shine.
She will be getting all five of my free votes when voting to save starts.
