Warning: This story contains Big Brother 28 spoilers from the live feeds.
Big Brother 2026 has already overturned its first Head of Household’s plan. Dee Valladares won the opening HoH competition and nominated Mallory Aurichio, Taylor Brown, and Yash Patel. However, Mallory then won the season’s first Power of Veto.
The result forces Dee to find another nominee before the Week 1 eviction. It also gives Mallory a dramatic escape after she emerged as Dee’s primary target. At the latest source cutoff, the replacement nominee had not been confirmed.
Big Brother 28 Week 1 Power of Veto Results Revealed
The first veto draw included six players. Dee competed as HoH, while Mallory, Taylor, and Yash played as the three nominees. Barrett Pfeiffer and Melody Morris joined them through the draw.
Mallory won the Power of Veto on Saturday, July 11, 2026. That victory should remove her from the block at the veto meeting on Monday, July 13, 2026. Taylor and Yash would remain nominated unless another twist changes the lineup.
Before the competition, Dee’s preferred outcome was a Mallory eviction. The live-feed strategy also identified Melody as Dee’s backup option. Therefore, Mallory’s win does more than save one nominee. It requires the first HoH to expose another part of her game immediately.
That is the central consequence of the first major Big Brother 28 Week 1 result. Dee began with a defensible nomination structure. She selected one player from each Time Trip competition group. Now, any replacement choice may look more personal and reveal where her loyalties sit.

Dee Valladares Wins the First HoH After the Time Trip Twist
Season 28 began with 14 new houseguests and a “Time Trip” theme. CBS introduced the newcomers during Big Brother: Broveal on July 7, 2026. The theme blends historical settings with nostalgic twists, including 1980s-inspired elements.
The opening competition divided players into historical settings and offered safety. Rome Seymour, Chuk Anyanwu, and Jason De Puy won their heats and earned immunity from Dee’s first nominations.
The same twist introduced three familiar reality competitors. Angela Murray returned after Big Brother 26, while Rick Devens crossed over from Survivor. Former Big Brother winner Rachel Reilly also appeared, but an ornery velociraptor pushed her into a volcano during the 175 million B.C. sequence.
Julie Chen Moonves then used the Time Table to travel to December 20, 2023. That date marked Dee Valladares’ victory on Survivor 45. Dee entered as the 17th houseguest after her identity was confirmed on Big Brother: Unlocked on Friday, July 10, 2026.
Dee had also returned for Survivor 50 and competed on The Challenge: Vets & New Threats. Her crossover made her the first person to compete on all three franchises. She entered the house with a direct goal: “I want to be the first person to win Survivor and Big Brother.”
The final stage of the first HoH competition featured Dee, Angela, and Rick. Dee won, giving the newest arrival immediate control. She then nominated Mallory, Taylor, and Yash, with one nominee selected from each competition group.

What Mallory’s Veto Win Means for Week 1
Mallory’s position changed within one competition. She entered Saturday as the houseguest most clearly identified as Dee’s target. She left with the only guaranteed power to erase one of the three nominations.
Dee’s next decision matters because the opening week has already produced visible fault lines. Naming Melody would follow the backup plan discussed before the veto. Choosing someone else could indicate that conversations after the competition changed the HoH’s priorities.
Meanwhile, Taylor and Yash still face the eviction vote. Their survival may depend on the replacement nominee and the alliances forming around the 17-player cast. The veto result also prevents the house from simply following Dee’s original plan without another round of negotiation.
This is where the early Big Brother 28 spoilers become strategically useful. A competition result alone does not determine the eviction. Instead, it changes which relationships Dee must protect and which houseguest she is willing to expose.

What Happens Next in Big Brother 28 Week 1?
The immediate question is Dee’s replacement nominee. Mallory is expected to use the veto on herself on Monday, July 13, 2026. However, the source material did not confirm the final renomination before publication.
The Wednesday, July 15, 2026, episode should cover the veto phase. The Thursday, July 16, 2026, episode will move the week toward its first eviction. Until the replacement appears, Taylor, Yash, and Melody remain the names most central to the decision.
Mallory’s win gives Big Brother 2026 an active opening week rather than a predictable first eviction. Dee still holds the HoH room, but the veto removed her preferred target. Her replacement choice will now provide the clearest early evidence of how she intends to play.
