First we lost Ashley (an original) because the roommates hated her then Lauren (Cory's ex) left because she got pregnant. Now, another roomie has left "The Real World: Ex-plosion" because of frustration and jealousy. Hailey, who was Thomas' ex decided to leave after a heated confrontation plus he was begging her to leave. He is currently dating his fellow roomie, Jamie so now we are down three! That's the most of any season I believe!
