Incidentally, I know what J/R should do this week so they'll be safe next week.
1. Evict Adam. More on that later.
2. Convince Kalia if she wins HOH to nominate Jordan and Shelly. Jordan would have to volunteer to go on the block, but still.
3. Throw the HOH.
4. Rachel would need to win POV, though the only real threat would be Porsche. If she did, Rachel would take Jordan off, Porsche would go up and walk out the door. If she didn't, Shelly would go up home instead. Since they evicted Adam, Porsche would literaly be the only competition.
5. With Kalia unable to compete for HOH, they would be default win it, and send Kalia home next week, with Shelly has their only competition for the final HOH.
But this is Dan level thinking, which we can't hope for with these people. Nor can we hope for Memphis level, or Dick level. Maybe Jun Song level thinking?
