The Big Brother 18 house is going to be rocked by another twist Friday night as one of the first five evicted houseguest re-enters the game.

Active houseguests: Bridgette Dunning, Corey Brooks, Da'Vonne Rogers, Frank Eudy, James Huling, Michelle Meyer, Natalie Negrotti, Nicole Franzel, Paul Abrahamian, Paulie Calafiore and Zakiyah Everette

Evicted houseguests: Glenn Garcia, Jozea Flores, Victor Arroyo, Bronte D'Acquisto and Tiffany Rousso

Big Brother 18 is airing a special Battle Back episode Friday on CBS, featuring the first five evicted houseguests competing to come back into the game. The epic competition is set up like Survivor's famous Redemption Island twist, where the first two contestants voted out battle in the first round, and the winner advances to battle the third person voted out and so on and so forth.

This means that Glenn will take on Jozea first, followed by that winner taking on Victor, followed by that winner taking on Bronte and finally that winner taking on Tiffany. Essentially, that means Tiffany already has a 50 percent chance of re-entering the house.

It's still unclear exactly what kind of competitions the evicted houseguests will participate in, but considering the whole Battle Back will take place in just one hour, they will probably be short. It's also not known if the final round will consist of Tiffany and another evicted houseguest competing in an endurance competition alongside the rest of the houseguests, making it into a combination HOH comp as well, like in Big Brother 15.

So who do you think has the best shot of making it back into the house? Obviously Tiffany has the best chance out of anyone, but there's still a chance that another houseguest could beast their way through the Battle Back and get back into the house.

Victor is clearly the biggest physical competitor, and he's proven himself in that Roadkill competition that he's good with math, too. Speaking of math, Bronte has a shot of making it considering she only has to beat two people, but she never won an individual competition in the house. Can she pull it off when she needs it most? Jozea and Glenn have had plenty of time off so if their minds are in the game, they could pull off an upset.

Either way, it should be an exciting night of competition - and an exciting new house dynamic.

Who will win the Battle Back on 'BB18'?

Big Brother 18 airs tonight at 8 p.m. ET/PT on CBS.
