After watching this episode, I have decided that Lexi is Satan, Katie is a saint, and Malia is still a spoiled brat. I do not condone any of the things that Lexi said to Malia. She was way out of line and her lack of a sincere apology made it worse. But rather than stepping up as a senior crew member and figuring out how to make the living situation work, Malia happily let Katie volunteer to switch rooms with her. I didn't even get that mad until Malia's talking head where she gloated to the camera that Lexi is, "Katie's problem now." Once again, what Malia wants, Malia gets.
