Twenty-nine seasons into MTV's "Real World" franchise, keeping the series fresh involves coming up with new twists to the format. A few weeks into the season, the seven castmates living together in a San Francisco house are startled to find that their exes -- with whom they have drama-filled histories -- have moved in, a first-time development for the franchise. It goes without saying the new living arrangement complicates the roomies' lives and leads to the fights, scandals, hookups and breakups that "Real World" fans have come to expect from the series. The cast includes a Bay Area native with commitment issues, a womanizing club promoter, and a former football star who lost his college scholarship because of a pregnancy scare that turned out to be a hoax. And good luck remembering who's who among the females -- there's a Jenna, a Jenny, a Jamie and two Ashleys.
