although I think he had to show the idol at that point to pretty much "guarantee" Julie stays....he worked that hard, no need to roll the dice if you don't have too....he was way past the point thinking the other 4 would listen to anything he said or any convincing argument he might make about keeping Julie...they were laser focused on Devens and knew with Julie around as his only working partner, her still being around would help keep him in the game.....think he had to show it
and on the bolded.....whether he makes the finals or not, this has been some of the best game play in survivor history IMO.....would be hard not to show it....the other players left know this is Devens game to lose and they may not be able to do anything about it.....knowing Devens has the idol, they have to start chopping at each other and that will mean working with Devens and allow him to slide right in...pretty much guaranteed if he wins another challenge...
