I hate to be on the other side of this but to me it makes perfect sense.

Julie was miserable when the storm hit. Wanting to call it quits, even giving herself an out by stating that she had promised herself that if it got too hard she could just go.
Julie, whether she likes it or not, is integral to Jeremy's plans going forward. To the point where he emphatically attempted to get her to change her mind and stay strong.
At this point it will become a choice between creature comforts and Jeremy's game as to why she'll stay or go.

From a logistics point of view: Production is hoping she won't quit. Things were still in flux when the first 2 peeps dropped out, but to lose another to a quit, (and possibly yet another with a med-evac) will force them to an F2 w/ 8 or 9 jurors. Just to have enough people left at the end. Best not to pile on the exits just about half-way through. Spread 'em out.

Plus, the wrinkle in the plan won't be because Josh was booted. I think it will be because Jeremy felt sure he had the numbers to oust Josh before Julie quit, but now he doesn't.

Honestly, I don't think she has it in her to last through the whole cycle and she won't have to as she will quit before even going to TC.

So, yes. JP arrives at Huyopa at dusk. Dressed in the same outfit he was wearing at the Immunity Challenge. To synopsize the recent event and to ultimately give them a reprieve from Tribal Council tonight.
