I'm still checked in on this season, as I love the mess. But Heather's weird vagueness about the black eye this last episode was a total jump-the-shark moment for her. That producers called her out on her contradictions, and that the show decided to air the fact that even they think she's full of shit, might even have been a jump-the-shark moment for the show itself. We'll see.
Once Jen's gone, I think they should all be invited back and given another shot at doing a season that this time doesn't have Jen sucking the air out of every room. This season has been less fun and more frustrating because the cast are on eggshells around Jen. The show needs room to breathe without her now, and I think the four remaining cast members, and the two Angies, are capable of delivering a good season once that's allowed to happen.
