I see your logic but you have to watch a few more episodes. Cody wanted to wait to buy the necessities in order to force flares. It worked with the morons who gave up their shoelaces and ended up with ruined feet.
The rest of the snowflakes had their tent and numbers so they bought 3k burgers 15k worth of pizzas at every opportunity. So they were fine until they got too lazy to boil water.
Now caught up, and wow... That’s some strangely confused people. ‘Don’t let x win’ - excuse me? What, are they supposed to push people off cliffs? All one has to do to ‘win’ is just not leave.
And probably the producers at this point are wondering what they can do to prop up the campers. Definitely one of them will be picked for the next temptation. I’m wondering, however, how many challenges they’re not showing us.
