Www finally experienced a major power shift in the Big Brother 18 house on Friday, with two houseguests who have felt safe this entire season are nominated for eviction.

Head of Household: Victor Arroyo

Nominations: Corey Brooks and Paulie Calafiore

Other houseguests: James Huling, Michelle Meyer, Natalie Negrotti, Nicole Franzel and Paul Abrahamian

After James, Michelle, Natalie, Paul, Victor and Bridgette Dunning pulled off an epic vote flip against Zakiyah Everette, it became clear that things were changing in the Big Brother house. However, the subsequent HOH was won by Corey, and the eviction that followed went by the older house dynamic, with Bridgette going out the door.

It wasn't clear if the dynamic might switch back to the all-guys alliance (+ Nicole) after Bridgette's eviction, but this was not the case. Victor won the HOH competition and while Paulie and Corey had talks with Victor and agreed that Michelle and Natalie should go up, Victor had other plans. Paul and Victor spoke about how they needed to get Paulie out of the house, with fellow strong competitor Corey being the backup plan.

Most of Friday was spent lying to Paulie and Corey, and pretending everything was going according to plan as far as getting the girls out. Both men were feeling very confident heading into the Nomination ceremony, as was Nicole, who won this week's America's Care Package, giving her safety for the week.

Victor indeed nominated Corey and Paulie at the Nomination ceremony, leaving them and Nicole stunned and confused. Paul confronted Victor about his nominations, trying to guilt trip him about being loyal to his fellow men. However, Victor stood his ground and spoke intelligently about how Victor was first evicted under Paulie's HOH reign and how he didn't even give Victor a chance to play in the Veto competition. Here, Victor is giving Paulie a chance.

Paulie went all over the house throughout the night, trying to get answers, with former close ally Paul pretending like he didn't know that Corey and Paulie were going up on the block. Paulie ultimately found himself in tears and told Corey at one point that if he, Paulie, were to win the Veto, he would use it on Corey.

Paulie also spoke to Michelle and Natalie separately, hoping to make amends, even though he mostly tried to play the victim. Natalie and Michelle later talked and Natalie said she knew Paulie wasn't being genuine during their entire talk.

Meanwhile, the all-male alliance was basically revealed to the rest of the house (a.k.a. the three remaining girls). For reasons unexplainable, Nicole expressed that she knew there was an all-male alliance and that she didn't particularly care. Paul directly asked her why she was so willing to be sixth and basically give up her game for this alliance, to which she essentially the boys are gonna do what the boys want to do.

The Veto competition will be held on Saturday, and assuming Paulie doesn't win, he's going home on Thursday. If he does win, then Corey will be evicted. Of course, there's still plenty of days to go before Thursday, and there's always the possibility that one of these men has the Round Trip ticket.
