You can see it coming together now, though. Phillip saw Reynold play an idol and Codename Pink does not allow anyone to display power who isn't him plus he already said those who had or used idols would be targeted. Reynold must be punished for what limited gameplay he has, so Reynold is next on the What's Stealth? Not Us block.
Meanwhile, Malcolm figures out that it was a great camera time move, seriously, right out of the Sugar Shack Handbook Of Pointlessly Pissing People Off Just For The Drama, but since Reynold isn't Randy, there's this little thing called potential consequences. And Reynold, whose innocence has now been taken so many times that he's the series first and only self-regenerating virgin, finally has his first moment of vengeance and directs what little forces he has to vote for Malcolm. And naturally, neither of them win Immunity -- nor does Phillip.
So. Reynold has one idol and has to have a pretty good idea (or would if it was anyone else) that Phillip will be gunning for him. So he plays his. That should be the automatic.
Getting Malcolm in the domino line is trickier, because he has to solidly know or strongly suspect two things: that he's the minority target -- easy guess -- and Reynold has the idol back and will be playing the thing. And everything depends on how he discovers the second part -- if he even does. Because it brings up the question of who casts the not-quite-throwaway vote for Phillip. And why.
Y'see, if Malcolm is playing on instinct - Reynold's way too confident at this TC, something's going on, oh crap -- he might just vote with his current alliance and wait to see what happens next. But if he's thinking on his feet, then he might realize that a double bounce with no one to land on could put them in a purple rock situation, and that's not a spin he wants to bet on. Malcolm could easily be the one who writes Phillip's name down, knowing it just takes one vote under the current nightmare and he just has to hope there's no scattershot throwaways in play. Good game, now explain it to the target in such a way as to gain his vote -- yeah, right.
But what if people knew in advance? Someone sees Reynold find, hide or secure the idol. Someone who isn't Phillip. And that person knows the scenario: one group targeting one idol holder, the smaller one going for the other, and total negation across the board. And for fun, let's say that person is part of Openly Operating R' They.
In fact, just for giggles, let's say it's Cockroach.
So now our crawler has worked out how to make the line tumble. He doesn't tell Phillip about the guaranteed idol -- in fact, he could do just the opposite, assuring their non-leader that it's a bounce all-clear, nothing to worry about, time to vote their troubles away. But he does tell Malcolm about the incoming bounce. Why? Because it gets rid of both current idols in one fell swoop. When they're rehidden (if), he gets a fair shot at the next. It's not as if anyone's ever going to give him one again. Removing that variable from the game provides him with a little safety margin. And then Cockroach votes for Phillip in order to restore some sanity, mainly that which people are slowly losing from putting up with this lunatic every day. Guess who probably becomes the new head of the alliance? Whoever he wants it to be -- remaining in the shadows, suggestions whispered from the dark.
Who cast the mystery vote, Phillip will demand to know from the jury. Who's the traitor? Who would Phillip like it to be?
Put it this way: if this is Cockroach and he pulls it off, he's getting his name back on merit.
It could be someone other than those two, of course. But the Cockroach edit has been on the upswing, while Malcolm really is chasing Sugar Road all the way to the inevitable 'How could I have possibly done anything to offend you other than offending you?' loss. There's a good chance this is our insect.
Not even idol nukes can stop it.
