Now it's starting to become clear

I was wondering what they were going to do to bring Boston Rob back in the game. I was thinking it would be something like the Extinction challenge will be heavily puzzle oriented to play to Rob's strengths, but now I'm thinking that having a lot of fire tokens will play a large role in either giving huge advantages at that challenge to put the odds even more in his favor, or maybe you'll just be able to buy your way straight back in if you have the most. It would be a big conspiracy theory type thing which I hope wouldn't be true, but for Rob to get to all those tokens before everyone else, there would have to be some straight up collusion involved by giving him some knowledge ahead of time so he would know about the fire token placements so he could familiarize himself with where to go to get them. It does seem pretty hard to believe he got to 3 idols before anyone else got to even one. Did they all go as a big group to each of the spots and not split up with some going to each?
