'Big Brother 25' Features an Undead "Battle Back" for Jared and Cameron (SPOILERS)

The Gist:

• Big Brother host Julie Chen revealed a "Scaryverse" twist.
• Many fans believe it has to do with a pre-jury Battle Back competition.
• This allows an evicted houseguest to return to the house and continue playing Big Brother.

At the end of the Sept. 21 episode of Big Brother 25, longtime host Julie Chen informed the two recently evicted houseguests, Jared and Cameron, that their games weren't over yet. As we all know, the reality show's motto is "Expect the unexpected," so what could this revelation entail?

Prior to this, many fans believed an evicted houseguest would return to the game via a "Battle Back" competition.

While Julie didn't use the actual term "Battle Back" in reference to what she has in store for Jared and Cameron, that is essentially what it is. Jared and Cameron are part of Scary Week in the Big Brother house, which means they returned to the game as zombie versions of themselves. And at the end of Scary Week, they have the chance to get back into the game as a real player, not just an undead houseguest.

According to spoilers from the live feeds, Cameron and Jared already competed in a portion of a three-part competition to determine which of them returns to the game. Cameron reportedly won a power to use in the Sept. 28 episode. The live feeds spoilers tell us that the power he earned will allow him to play the final part of the Battle Back competition alone, or choose to have Jared play it solo.

Whoever plays the final part determines which of the two houseguests will re-enter the game. If Cameron plays the final part and wins, he gets to be a full-time houseguest again. However, if he loses, then Jared re-enters the house permanently by default. There is a lot on the line for Cameron (and Jared) with his decision.

Before the Scary Week zombie twist was revealed, fans were sure there would be some kind of Battle Back. On Twitter, some theorized that producers might unveil a Battle Back competition for Cirie or Jared. It's painfully obvious that the Big Brother producers want the mother-son duo to be in those final two seats on finale night, so we wouldn't be surprised if a twist worked in their favor. Sadly, that would mean Cameron is sent packing for good.

Regardless of who comes back between Jared and Cameron, they are both part of Scary Week in the Big Brother house. Season 25 features different "multiverses" of Big Brother, including Comicverse, Humiliverse, and of course, Scaryverse. This is another way for producers to shake up the game as the season moves along.
