It's the Power of Veto, Zach and Donny remain on the block and Christine is HOH. Sounds like a recipe that will lead to some sadness for at least one or maybe both of the season's favorites on the block.

The episode starts with Frankie realizing that everyone in the house is pretty much after him. Frankie thinks that the only way to solve the situation is to reveal the truth about who he really is: a pop star's brother.

Zankie start to argue. Zach is calling out Frankie on being a liar and talking behind everybody's back. And then Caleb drops the bomb on Frankie about why everyone is after him. Frankie comes clean and says that he did tell Christine and Nicole to put up Derrick, Caleb and Cody. Derrick, being a cool cucumber, tells them to fix this all behind closed doors. But all of this just leads to Frankie coming clean that Ariana Grande is his sister. Frankie refers to himself as a "media mogul" and tells the guys that he's playing for a charity. The reaction is hilarious. Cody thought Ari was a dude, Derrick thought her name was Amanda and Zach just says nothing.

So then Frankie goes and tells the girls that Ariana is his sister. While the the girls reaction is very different than the boys and they're all excited, the DRs thankfully tell us a different story. Christine thinks Frankie is boasting and that he's going to get backlash. Correct. Victoria thinks that he's using his sister as an "escape goat". She meant scapegoat but at least she gets it! Atta girl Victoria. Looks like Frankie's truth telling may be backfiring.

And there's Zach. The poor kid is incredibly hurt by the news. His DR session featured him crying and screaming at the camera. He believes that no one will stand a chance of winning. The tears are convincing but I can't help but think that maybe Zach could be playing it up.

Derrick reveals that his plan is to have Victoria as his secret weapon. No surprise there. Very smart on Derrick's part and part of me hope it works out for him.

Players for the veto comp are Christine, Zach, Donny, Caleb, Derrick and Nicole. It's the famous OTEV competition! OTEV, the pissed-off penguin, will ask the players to get him a drink that will have a houseguest name on it that answers the clue given. Unfortunately, Donny is the first person out, followed by Nicole, Christine, Derrick and Caleb. That leaves Zach as the winner of POV!

So now that Zach is completely safe this week, he thinks it's a good time to start showing his entire game. Of course, with Victoria being Victoria all she takes away from Zach's confession is that Derrick is playing her. Magician Derrick now has to figure out how to get Victoria back in his pocket.

Power of Veto ceremony is here and Zach has the power. He saves himself and Christine nominates Nicole in his place.

Find out if Nicole or Donny will be evicted Thursday, 9/8c on CBS.
