It's not working, but I do think she's trying and I'm getting frustrated by why so many players feel she doesn't deserve to be there!
Having just recently watched from the point where Kat got voted out till the end, I realised it must have been frustrating on her for sure. One moment Kim and gang are hugging her at challenges and stuff and yet another moment they are saying she is least deserving. She got a real good bashing at her final council for not trying hard enough to fight back... Damn, girl had it going hard for her...
Dani, I totally forgot that she blew up in episode 2 like that. Its probably the most character and emotion I've seen from her. Either that or the editors left out a whole bunch of emotion on the editing floor. She seemed pretty lifeless and emotion-less most of the season unfortunately. Now, if she had more of that "no, you're wrong. SO SHUT UP!"-ness through the season, I think she would have been more memorable.
