I agree with you in that Simone and the guy (black couple) will get married. Now that the one girl got rid of her hook up buddy, I think she and Larry seem like they are serious about each other. I don't have much hope for the rest. This season went fast and I kind of feel like the show really didn't dig very deep in addressing the troubles between the couples. Like Pawel and the girl (long dark hair) - I'm feeling like zero chemistry - at the beginning of the season and now. It doesn't seem like they've grown at all as a couple. I think Mario will revert to his old ways because his buddies are probably dudes who like to hang out at bars and chase women (they're the ones he went with to the happy end massage parlor). I wish they would have done something to see how Mario would behave around his friends. Can't believe how young Mario's girl is - only 22! Blonde girl and Dustin should definitely stay apart.
