I thought last night's episode was entertaining--loved seeing Steve so sure of the psychiatrist, but I wish there had been another viable suspect/theory so it could have been more of a win when he was proved right. As it was, it looked like he was relying on his gut a little too much but not all that off base. I wasn't surprised at all when she turned out to be the killer. And Steve already has someone in his life who challenges him whom he seems to enjoy a great deal--Danno.
The stuff with Mama McG is all over the place. I did like that Carlos Bernard was back and watching him and Catherine team up was fun. Possible love triangle? I also had to chuckle at Catherine telling Steve that he doesn't make a good first impression. He really doesn't.
