It's the end of the road for Jatalie in the Big Brother 18 house. With both James and Natalie on the block, the showmance will officially be split up this week. But if Paul, Victor, Corey and Nicole get their way, James and Natalie will be reunited soon enough in the jury house.

So who won the 12th week in the Big Brother house? Check out our power rankings below. (For previous rankings: Week 11, Week 10, Week 9)

Nicole: Twelve weeks into the season and this "snake" has still never been on the block. And by staying friendly with James and getting Paul and Vic to go after Natalie, Nicole has set up an easy backup plan if none of her Final 4 alliance members manage to win HOH.
Grade: 7.5 (Season average: 5.3)

Victor: Surprise! Vic won another comp. And while Victor initially wanted to evict the person who evicted him (for the second time this season, mind you), he was convinced to target Natalie instead. This decision definitely benefits Nicorey far more than it does the Sitting Ducks, but Vic is still sitting pretty overall.
Grade: 7 (Season average: 6.1)

Paul: Paul is like teflon recently. After Meech attempted to put a target on him during her eviction speech, Paul has only strengthened his alliances with Victor, Nicole and Corey. Paul is so close to reaching the finale, he can probably taste it. If only he still had Pablo to share these sweet victories with.
Grade: 6.5 (Season average: 6.3)

Corey: To the shock of many, Corey managed to win a mental comp and secure the Power of Veto. Maybe he's more astute than he appears!
Grade: 5 (Season average: 4)

James: James is is a bad spot right now. Despite him campaigning to save Nat this week, he'll likely be sticking around but with an even bigger target on his back. If he wants any hope of making it to the final four, he's going to need to win that HOH this week.
Grade: 3 (Season average: 5.5)

Natalie: Everything Natalie told Victor and Paul about how trusting James' strategies hurt her game was true, but throwing her ride-or-die under the bus like that was a terrible move. And the thing is, James had already made it clear that Natalie never wanted to flip against Paul and Vic. If she had asked James to go with her and have that convo together, it could have helped her game instead of making her look like a traitor. On the plus side, at least Nat's getting evicted because the other houseguests view her as a threat, which is something few probably predicted when the season began.
Grade: 2.5 (Season average: 5.9)
