Ru's little chat was warranted and needed. You don't compete to come on a show like this and then just get up and leave because you're not feeling it.
Kahanna should've gone home last week. When she was having her chats with the girls, she even said something like "I don't think I have any more to give". I was shocked that Kandy sent Jaymes home and even more shocked the other girls agreed. I think they're just trying to get out a fierce competitor in Jaymes.
