Following Sunday night’s Whacktivity Competition, Jack managed to get the special power that could change the fate of this week’s two nominees or seal his fate in the hit CBS reality TV show.

The Chaos Power gives Jack the opportunity to announce a do-over before a Power of Veto (POV) competition takes place for the next couple of weeks. As the owner of the secret power, Jack could completely change the POV players and ask the two nominees and the Head of Household (HOH) to choose again.

What makes the Chaos Power interesting is the fact that if Jack is up on the block, and he’s not happy with whoever will be playing in the POV, he could change things up to benefit his game.

This week, Jack also happens to be the HOH, and he put Jess and Kemi up for eviction. It has already been revealed that Sam won the second POV of the season, but it is still unclear if he will use it on either Jess or Kemi.

If Sam decides to keep the nominations the same, it is unlikely for Jack to use his Chaos Power on the two people that he wants to be evicted. Additionally, Jack did not use his secret power before the POV competition commenced. This means that he has to wait another week before he could use it.

Meanwhile, even if Kemi or Jess will be evicted this week, they won’t be out of the game completely. They will still have the chance to return to the competition and bring home the $500,000 grand prize by winning in the upcoming social game.

Details on how they evicted houseguests could return to the house are still being kept under wraps.

“Big Brother” Season 21 will return to CBS on Wednesday at 9 p.m. EST.
