Jessica had nominated Josh as her target because he didn't get along with Cody and herself. In fact, they often get into heated arguments.
As a way to avoid getting more blood on her hands, Jessica had nominated Ramses for eviction as her pawn because he didn't have any allies in the house. Jessica also thought Ramses made for a good pawn because he wasn't really a threat to anyone's game.
In the end, Jessica, a 26-year-old VIP concierge from Cranston, RI who currently resides in Los Angeles, CA, won the Power of Veto competition.
Jessica's PoV victory set her up in a nearly-unstoppable power position. Not only is she HoH with the veto power, but she also has her boyfriend Cody back in the game as well as "The Halting Hex" temptation, which will allow her to stop an eviction before votes are cast in order to save herself or someone else on the chopping block whom she'd like to protect.
Jessica was in complete control, but according to the live feeds, power in the house shifted when she decided to keep nominations the same at the Veto Meeting.
Jessica kept Ramses on the chopping block thinking the whole house would get rid of Josh. She also wanted to establish trust with some of her fellow houseguests and repair relationships that had been damaged when Cody previously served as Head of Household.
However, the majority of the house has a different plan in that most players want to vote to evict Ramses so that Jessica doesn't achieve her goal this week. The only people working with Jessica and Cody are Mark Jansen and Elena Davies, so this group will probably be blindsided.
Meanwhile, Josh has been laughing it up to cameras thinking that Jessica screwed up royally, mainly because he hasn't bothered or offended anyone else in the house besides Cody, Mark and Jessica. The other houseguests don't have a great reason to evict Josh at this point in the game.
Jessica's reign as HoH would have been successful had she nominated a big threat in Ramses' place -- such as Paul Abrahamian, whose ouster would look great on Jessica's Big Brother resume -- or a houseguest whom everyone loves and wouldn't vote out, such as Raven Walton.
Both strategies would likely ensure Josh's eviction or at least paint Jessica in a flattering light for the future Season 14 jury.
Jessica was initially worried about keeping her nominations the same and considered nominating a different threat, Alex Ow, in Ramses' place; however, Cody convinced her that everyone would definitely take advantage of the opportunity to get rid of Josh.
Since Jessica and Cody wanted Josh gone so badly, they also didn't want to risk nominating a big target in fear that person would be evicted instead. (Although the result would have been better than losing a floater like Ramses).
But now it looks like Ramses will get evicted this week and the houseguests will keep Jessica, Cody, Mark and Elena in the dark about their intentions. Alex, for example, told Jason to pretend like he hates Josh to make Jessica believe her plan is working.
Ramses' potential eviction will not impact Jessica and Cody's game positively in any way. And as for Mark, he's made himself a target in the near future because he has become all buddy-buddy with Cody again.
