Honestly I don't know exactly what I think of the new house guests but here is what I think:
Nick is my favorite character at the moment and has a good chance at winning, and I like everyone in his new alliance. I don't think Elissa will last because her secret was revealed the first week and that puts a very big target on her back. That's really all I can think of right now... but I guess in time I will know the house guests very well.
