Curious to see how this POV plays out.
Devin will use it to save Pao Pao.
Pao Pao will use it to save herself. Is there a comp she can actually win, though?
Derrick and Amber would have never used it as they're looking to keep the noms the same.
Zach might have used it prior to that ridiculous Bomb Squad meeting but he won't any more now that Caleb has sold out Jump Street to the HOH as wanting him out.
Brittany winning it would be the hottest mess of the bunch. She's been somewhat of a basket case and while they were making strong headway towards talking her into not using the POV on herself, the mere fact that the Bomb Squad is very likely to get leaked in the next two days and she's going to find out all of these people that she trusted were aligned and working with her nemesis... well, I wouldn't blame her for using the POV. She ought to under any circumstance.
As far as replacement nominees go they still have to pacify Devin until the veto ceremony if either he, Pao Pao or Brittany win the veto that the Bomb Squad is still intact so he'll throw up Victoria as a replacement nom. And they have to do this while not spilling shit to Caleb who is a loose cannon who can't be trusted with any information and will take it personally if he is shut out and not the center of attention.
After the veto ceremony they can effectively socially outcast Devin and Caleb while they sit by themselves in the HOH room while they get visits from Jocasta. But until then, we'll see eggshell walking at its finest. Unless, of course, Derrick, Amber and Zach win POV. If they do, they can transition into that phase right away.
Poor Pao Pao.
