The Real World returned Monday, but the real drama is set to take place 28 days later when new house members arrive.

In The Real World: Ex-Plosion, the seven strangers that were picked to live in a house see a ticking time bomb that producers flash on a TV screen every now and then. The bomb is counting down the days to when exes of all the cast members arrive, though the seven co-stars do not know that at first. For now, fans got to see relationships formed that will surely be tested when the others arrive.

Relationships already being made

Personal trailer Cory and rich girl Ashley almost had the first house hookup. Ashley was super drunk and Cory was going along with it, until she threw grease in roommate Arielle's face. Being incoherently wasted wasn't a deal breaker for Cory, but the rudeness that followed was.

He moved on to another housemate and gave viewers the first first sexual encounter of the season. Cory and Jenny had sex moments after, in producer time, but it was definitely the same night.

Thomas and Jamie were seen cuddling under covers, but nothing further was shown or hinted at during the episode.  However, trailers for upcoming episodes show them forming a relationship.

House fights are taking place

Ashley went up against everyone when she got drunk. Her behavior got her into a bit of heat the first episode. Her actions were sloppy and her words were extremely rude. At one point she said, "I can buy and sell all of you in this house." Ashley was provoked at first when Jamie told the guy she brought home that she has a boyfriend and tried to get him to leave.

What's to come?

Simply put, ex-girlfriends and boyfriends. Their arrival will shake up the Real World franchise and bring it out of recent obscurity. In trailers for the upcoming episode exes are seen fighting with new boyfriends and girlfriends, and decisions will have to be made on whether to go forth with a new love interest or dive back into an old one. Cory and Jenny's ex are seen getting into a tussle while Jamie tries to convince Thomas not to trust his ex.  There's also a pregnancy that will take place.
