The Big Brother 16 houseguests have been in the house for several days already, and as such, they have already gone through the nomination ceremony and the new Battle of the Block competition.

Big Brother live feeders got their first taste of what's really going on in the house last night, and it appears that things have shifted.

**SPOILERS BELOW**

Caleb chose to nominate Donny Thompson and Paola Shea for eviction, while fellow Head of Household Frankie Grande nominated Brittany Martinez and Victoria Rafaeli. Donny and Paola were the first people from their respective gender to drop out of the HOH competition, while Brittany and Victoria were the first two overall to drop out of theirs.

For the Battle of the Block competition, which featured Donny & Paola and Brittany & Victoria facing off in an attempt to get off the chopping block, it was the latter pairing that won. This means that Brittany and Victoria are no longer nominated for eviction and the HOH that nominated them, Frankie, no longer holds his power as HOH.

As for the target this week, many houseguests have agreed that Donny should be the one going home. Caleb and Paola agreed that Donny seems too smart and hard to read at times.

Meanwhile, Frankie and Zach Rance shook on a Final 2 deal, with Zach telling him that he has Cody Calafiore and Derrick Levasseur. Frankie told Zach that he is working on getting Christine Brecht in with them, agreeing that they could all be a five-person alliance.

Caleb had a conversation with Cody and Zach, who were randomly selected to play in the Power of Veto competition, and they all agreed to keep the nominations the same if any of them win. In the event that Donny won the Veto, they said they would put up Joey Van Pelt and backdoor her.

The next episode of Big Brother 16 airs Sunday at 8 p.m. on CBS.
