Not like they KNEW what the next challenge was going to be so can't really say voting off Jelinsky cost them the challenge. I think Jess not having access to her ADHD meds really affected her. Being introverted didn't help either. But them losing that challenge was not all on her. A lot them have had poor performances so far. I pointed out last week when we were watching that Tiff was pulling on that stupid gecko when Jeff was telling them that they had to lift it over. Just a stupid tribe overall. Not quite as bad as the Lulu tribe.
Another thing is the whole fake idol. You already have numbers, why play that card so early in the game? I understand they didn't want her to play her shot in the dark but there are other ways to go about it and not have to waste the fake idol play. I feel like they were beating Jess down even more when she was already on the outs. Feel similarly to how they are treating Venus on the other tribe. A little bit of bullying going on.....
