I was worried about the opening this season, mostly concerning spoilers that turned out to be true (Risha and Sindy nominated and Canada public vote), and I am still a little wary about the emphasis placed on big moves and the Vault. Big moves have to come naturally from the state of the game, and can't really be 'forced out'. I think they might have an instant eviction or two and call the results, no matter what, a 'big move'.
Hopefully the public votes are here only for the first week too! I cast a vote to evict Pilar, only because I'm more interested in Risha and Pilar has the air of a constant pawn about her, despite her tragically short air time in the premier.
I heard from somewhere (probably twitter) that Graig was supposed to be on last season, but had an accident (car related I think?) and was replaced by Jon!!
