6 shooter was dumb to blindside nick and Bella by voting off Cliff, they tipped their hand to Nick and Bella and created drama before having the power. IMO you go along with them and if you have power this week then you flip on them, if you do not have power this week then Nick and Bella are still fighting for you in HOH or veto competition.
Christie was so dead set on Nicole staying is better for her game, but the cost was blowing up your alliance before this week. Now if Nicole, Cliff, Kat, Bella, (insert big girl's name here) or even Sam win HOH, all of 6 shooter could be in jeopardy. There could be 2 of 6 shooters on the block or there could be 1 - 6 shooter on the block and you only have 5 votes to protect your core alliance forcing a tie and the HOH picks the evicted house guest.
I am happy to see game play, but I would prefer to see intelligent game play, not emotional Willy nilly moves. Christie freaked out because she was turning on Nick and Bella (they should have identified her break down as an indicator that she was turning on them and she got scared they knew) and she blew up the game with her emotions.
Poor game play all around IMO.
Sorry if my head count is off, some of these people are just so forgettable.
