TBH, I don't care who wins this abominable series, but I think it's been very good PR for Katie, for the most part. I think out of all the housemates in there, she's the one who has turned it around positively for herself and it doesn't matter if she goes or if she wins.
She was one of the most hated X Factor contestants and even got my back up at the time, but after seeing her on this, I've actually done a 180 degree turn on my opinions of her.
For the most part, she comes across as fairly likeable, interesting, at times even funny, and I don't pick up on any dark conniving undertow to her. As long as she doesn't screw it up for herself from here on in till the show ends, I think she's comes out of this debacle smelling of roses compared to some.
