For the second time this season, Big Brother 18 is airing a Friday episode. But unlike last time, this week's (probably) won't be as dramatic or game-changing as last month's Battle Back episode.

Friday's episode will be a country fair-themed special, featuring a performance by Ziggy Marley (this won't be news to livefeeders). The fair will include competitions for the houseguests to duke it out for "prizes, perks and power," according to CBS.

But since we have to expect the unexpected, there has to be more to it than a free concert, right? The episode will, obviously, air after Thursday's live eviction, so the evictee (cough, Paulie, cough) will be in it, which seems counterintuitive unless Friday's episode is merely just fun and games. But since Thursday also marks the end of the round trip ticket twist, do TPTB know one of the nominees has the ticket and will return?

Or could someone else return, like a juror? The round trip ticket twist means the show is prepared for a second double eviction in the event of a round trip returnee. Why not make it a reality with a returning juror?

Big Brother's Friday episode airs at 8/7c on CBS.
