1x08 Beware Those Closest To You
Well that was an episode and a half (literally too!)
So my thoughts on this are that the real bluff happened after the fake bluff. I think they knew that Gabriel was too clever so they put in place a fake bluff, because he would be expecting that. Then everything that happened after that is in fact, the real bluff. Knowing that Gabriel has eyes everywhere it needed to be really believable and they had to trick us too. Maybe I'm wrong and we'll find out next season, but something makes me think it wasn't all real.
