These people are the dumbest BB HGs ever. The only person Christie is loyal to is herself. The only "longevity" she cares about is her own. If they all choose to believe in her "authenticity", they all deserve to lose. When Nick is gone, she'll just find someone else to vilify. She's done it all season...Bella, Sam, Jackson. She has been playing the game that she's accusing Nick of playing, and he should have pointed that out. Not rooting for Nick, just hate her hypocrisy.
That being said, Analyse is no great loss. She'll be just as happy with Jack in the JH.
