Kari is quite hot, however on a recent episode I saw (the one with the ceiling fans that supposedly decapitated someone), they had another hot babe, this one blond and tattooed working along with Kari. And Kari had to excuse herself from one test, because she is a vegetarian, but the blond wasn't. Who was the blond, and where is a photo of her?
She is not on the show anymore as far as I know.
She is also quite spanky in her own way.
That was Scottie. She left the show when they went to the build-team/Adam-Jamie format. She has been back on the show occasionally.
