It was so obvious that Karofsky or whatever his name is, picked Marissa to win the homework challenge based on the fact that he wanted to get in her pants! Ironically, it backfired and got her eliminated. Goes to show how much that guy knows anything about acting. It was the first time that a homework assignment challenge winner got eliminated. Samuel should have been the winner of that challenge. He obviously put his heart out there plus he initiated it which caused the others to follow suit.
That being said, Marissa should not have been eliminated. For some reason, these gay judges have the hots for Cameron and they do not want him to go home. I thought he was going home for sure this time. Wasn't surprised when he was saved the last couple of times but this last one was a big surprise. He's just not very good in acting (and dancing for that matter). Alex is a great singer but he's a stereotypical gay guy which the show already has plus he doesn't work as hard whenever they practice. Maybe they should audition for American Idol, The Voice, or The X-factor. I think they will have a much better chance.
