There have been a few times where people have been duped into playing a fake idol, but there was something about this one that was just so epic. I mean hook, line, and sinker, Jay didn't even question it. Which I find a little odd. It didn't appear that David had put an official note in with it, so there was nothing with it to say "Yes, this is official", like normal and Jay had an immunity idol already and saw several others played. They were kinda teardrop shaped. He knew what they looked like and didn't question that this one didn't look like all the others. So yeah, crazy epic play on David's part.
I'm quite pleased with how this ended up. Adam really deserved it, though Ken winning wouldn't have bothered me all that much. Hannah, I guess I get what she was saying, and for a while there, it started to look like she was being very convincing, but clearly nobody was buying it, and that's good. Adam needed to keep it in everyone's head that she was all over the place and somehow he did.
And I was also surprised at the amazing lack of sour grapes on the jury. Usually they're bitter and pissed off and just assholes about it and they often (IMO) give it to someone underserving, because they're so mad at the deserving person that they fuck them over out of spite. Really glad to see that didn't happen this time around.
