So.. the end of last episode reflects much of the things happening here - Matt and Emily have to deal with each other. Getting over that they break up and see each other every day. The case they get will even more reflect their feelings that they realize - married couple goes nuts over a nothing and man takes his best friend hostage, wife runs to his mother's house and take her hostage. Crazy.. and even more crazier the episode goes and while trying to sort out their relationship it looks more and more like they are solving their own problems.
So, considering, this is the last episode, not too bad, but I would have wanted something else.. The whole break up thing.. I think they could have managed it without it.
