And yes, Viviana needs to be slapped around by one of the other women. I cannot stand a person who is so full of themselves, that they cannot see the truth about themselves. It was in poor taste that she spoke out against the martial arts master, especially since she had no previous experience. Now if Matt had spoken out, you could accept that, since he had been doing martial arts since he was 7.
So she was totally out of line and if she makes it to the final 14, she will only be good as the villian/person to make fun of.
