I'm bored so here is my random thoughts on some possible power rankings after this episode. Feel completely free to ignore and move along.
Top group(most powerful, or in the best positions):
Sophie, Jeremy and Denise.
Sophie has an idol no one knows about, walked in to merge and completely read the lay of the land and was able to seeminglyl steer the vote.
Jeremy has a get out of tribal advantage, has probably the most ties and relationships in the game and was willing to tow the line with the majority and realize he wasn't going to be able to save Wendell. He has people like Ben, Tyson and Tony going to him when they want to keep big players and targets in the game and it's literally Jeremy's entire gamestyle. He's already in a majority and he has the outside players coming to him. It's hard to not see him in a really strong position.
Denise is just Denise. She just played 2 idols, was the sole vote for Sandra, and walked away from it without even being considered the largest target on the 4 person swapped tribe. It was also telling that people went to her and talked to her about voting out her closest ally. They trusted her enough to not leave her out of the vote when she was the most likely person to give that info up. Something not awarded to Michele and Nick.
Second grouping(really good position and ties, but not as much power or decision weight)
Sarah, Ben and Tony.
As I said above I think Ben is playing a really strong social game and is probably coming out of this merge episode with the most strong bonds and ties in the game. If his idol finding prowess comes back around I think he'd have the most knowledge in the game to know when and where to use them.
Sarah has her advantage and her close ties with Sophie while being aware of Sophie's idol. Coming in to the game as one of the primary targets and being at this point shows that she has that strong social game that gave her her win in the first place.
Tony is at the lowest end of this group, but I feel like it goes without saying that him even being to this point shows he's doing something right. Not only that but he has the potential for a lot to come out. I don't think he really has much power, I don't think he's really all in that amazing of a position, but he's not being a target at merge and for Tony I feel that that is pretty huge on it's own.
Limbo(This is a group I'm not entirely sure on)
Kim - I just don't know where her real stance in the game is at this point. She would never be a strong merge boot, so we just need another episode to really see where she stands.
Michele - I still hold that Michele has a lot of ties in the game. I think this vote was somewhat of an anomaly for her. We saw Jeremy was tight with her, but they didn't go to Michele in talking about voting Wendell out, but they did go to Denise about Adam. Is this seeing Michele as less worrying or was it just understanding she was closer to Wendell than they wanted?
Adam - I'm so confused by this guys stance in the game. You would think Adam was the easiest vote here at a shaky merge, and no one seems to have too close of ties with him. But...he sticks around?
Bottom:
Tyson and Nick
