Based on the level of reality defined by the rest of the show, I do find the Urie/Routh relationship believable. Much more so than the gay couple in New Normal. The more I see Urie both in performance and interviews, the more I love the guy. Even with old jokes you see coming from a mile away, Urie still manages to make them seem fresh and hilarious. And I don't know if it was the character or the casting that came first, but Routh is just spot-on with everything he's doing, which was the biggest surprise to me for this series. But having the sassy latina constantly hit on him was a tired joke after the first time.
Namo, I agree about the fiancee. She's the major weak link in the cast. She's a paper doll to the rest of the cast.
