---

You'll notice that each of them highlight the quit/med-evac even if they are veiled attempts at doing so.

The fact that the misdirection this week seems to single out Julie as the castaway to contemplate throwing in the towel, (when she clearly had already reached that breaking point last episode but was talked out of it.) means that she will most likely move forward with those thoughts this episode.

I'm thinking we'll here a bunch of talk about what everyone is hoping will happen at TC, that lines will be drawn and factions formed, then Julie quits.
Leaving room for Ep8 title of "wrinkle in the plan".
