Spoiler Alert! Everything to Know About This Week on 'Big Brother 25'

SPOILER ALERT! This article contains events from the Big Brother 25 live feeds that have yet to be aired on the television episodes. Please don't read ahead if you prefer not to know competition winners and nominees ahead of time.

To say it was an eventful first week on Big Brother 25 would be an understatement. A surprise 17th houseguest entered at the end of the premiere in the form of Survivor legend Cirie Fields. Two sides of the house seemed to form quickly, only to disintegrate. And a racial slur said by contestant Luke Valentine led to his expulsion. With things left in chaos, Week 2 is crucial to see how things will look, and who will be evicted next.

Here's everything you need to know about this week on Big Brother 25, including Head of Household and veto winners, nominees, and who is likely to go.

Who is Head of Household this week on Big Brother 25?

Hisam Goueli

At the end of Thursday's eviction episode, the houseguests were nowhere to be found. We closed the night with a portal closing, seemingly to the "Scary-verse." But things were far from scary for Hisam, who continued to competition dominance by winning his second challenge in a row and becoming Head of Household.

Who was nominated this week on Big Brother 25?

Cameron Hardin & Reilly Smedley

Not only are Cameron and Reilly both part of the "Handful" alliance that formed last week, but Hisam also got word that both had talked about targeting him this week should their side have won Head of Household. Those made it easy choices for Hisam to nominate them, with Reilly as his target.

Are there any twists this week on Big Brother 25?

Last week, it was teased that the "Nether Region" would not be so kind to the houseguests after letting Cory Wurtenberger go after an hour away during premiere night. That came to fruition during this week's Head of Household competition. Jared Fields placed second and, as a result, was taken away to the "Nether Region" for an unspecified amount of time. He returned later on Friday, only for Jag Bains to take his place.
