It's day 36 for them, no? No more time for the subtleties I think - several of them at least are clearly building their jury cases.
Chrissy's is looking good in that she's had a high level of control/influence throughout the game (very clearly illustrated to the jury when Jeff talked about the choice of Ryan over Ashley at the reward, then Ashley's demise over Ryan or Mike), and with two immunity challenges now, has that on her resume too. For jurors like JP and Cole, that's going to count.
However, the people who like her most may be sitting right next to her at the final rather than on the jury advocating for her, so we'll see. Also, several of them have commented in interviews that Chrissy doesn't like women - and there she is in final 5 with 4 men. The jury is also mostly male - comments have been made by fans that Chrissy got rid of them all pre jury on purpose, but that's just theorizing. One wonders though if it's true, and if so if it will backfire when a mostly male jury goes to hand a million dollars to someone who outplayed each of them.
[fun fact - trolling around social media it appears that Ali, Jessica, Roark and Desi have become besties since filming last April/May]
Looks like Ryan will be at the end since no one is targetting him, but I don't think he's got enough of a case. While his strategy has been very good and he has strong alliances, they might very well be with him at the end and thus they become opponents instead of useful allies. Plus, word is that he contributed zero around camp - didn't even attempt to fish, crack a coconut, cook rice or tend the fire. If it's true, that kind of work ethic does not wash with people who were categorized as Heroes and Healers, or Lauren, who now make up the majority of the jury.
Devon's actions this ep puzzled me until I remembered his early and strong alliance with Ryan. Much as Ashley would be a great one to take to the final as I can't imagine she'd get any votes, Ryan is the one who is more likely to get Devon there and he might feel confident he's got the better resume - which I think he does.
I know they've all been worried about the Marine factor, but I'm surprised we're not getting more of what a threat Mike is because everyone loves him, and he has a great "least likely" to "wow he's really surprising us with his abilities" story that could contribute to a win.
Hard to predict F3 since much depends on immunity now, but my money's on Devon for the win. And I'd be happy with that.
