This all makes me want to see Marquesas again.
I am into discussing past seasons. So, let's have at it.
I am not overlooking the differences between what Rob and John did. I am just pointing out the similarity that in both cases the bootee was of questionable loyalty and had the ability to make a tie.
We both know Gabe was loyal, but in Survivor, when someone is questioned about their loyalty and they respond by saying they aren't playing the game, it is typical that trust is lost.
John wasn't sure of Gabe's loyalty, and as you like to point out, he was closer to the situation than we were.
As I like to point out, is Gabe going to force a tie? Unlikely, but John saw an opportunity for an easy advantage and took it.
Really, it is also similar to what Kim did with Michael. Michael was a Salani, but she knew members of her own tribe were willing to boot him. So she took advantage of that to get him.
It could have caused the same paranoid reaction in Troy and Jay. In fact, it partially did. Fortunately for Kim, Jay was a fool who was probably as entranced with Chelsea's smile as anything.
And lastly, it didn't take his 4th try to win. B-Rob won the biggest prize of anyone in his second try.
