Just like production footed the bill for Christy and Todd's trip to New Orleans. Nothing really happened this season. Aside from the usual arguments and shadiness. Terra announcing her pregnancy really wasn't that interesting (at least not to me). There was an angle there with Brianna's relationship with Matt. Him being wherever he lives doesn't really help that storyline, out of sight, out of mind. So, lets fly him out to California and have some kind of drama.
I didn't believe for a moment, that the three T's took it upon themselves to 'investigate' Matt. More like, production gave the information to Terra, and wanted her along with Sour Puss Traci and Tonya to confront Brianna with it. Even those moments were a dud because Brianna is such a meek pushover. Not one to raise her voice or get it anyone's face.
