One of my favorite guest stars on The Mentalist, Morena Baccarin, returned as captivating murderess Erica Flynn on "War of the Roses," which highlighted Erica's way with men and her ability to get under Lisbon's skin.

First off, did anyone else notice the size of Erica's prison cell? I'm no expert but it seemed a little large. I think my first apartment was smaller.

Jane was quick to call Erica on her line of bull. She cared deeply for Natalie? Ha! More like she knew the woman and realized she could work the angle to get some time out of her prison cell. A lot of time, actually.

I loved how irritated Lisbon got around Erica. It just bugged the heck out of her how this convicted murderer (or is it manslaughterer?) was able to wrap any man around her little finger. Even better was when Grace said she could understand Erica's appeal if she were a man. That's not what Lisbon wanted to hear.

Lisbon despised that Jane was attracted to Erica and wanted her help on the case. And when Jane told Lisbon she couldn't send Erica back to prison yet because he needed her, he looked terribly pleased that it obviously bothered her so much.

Erica and Jane definitely had chemistry. You could feel her pull as Jane couldn't help but kiss her in the hotel room. I was almost surprised when he turned to leave.

Jane's bit as a clairvoyant at the fundraiser was fun. I've always loved watching him use his so called psychic abilities. He's so damn good at it that he could convince anyone of almost anything. It's a dangerous talent.

I'll admit that I was happy that Erica got away. It seemed a shame to bring such an entertaining character back just to ship her back to prison. And as much as Jane would haul her back to jail given the opportunity, I think he was a little impressed by her escape as well.

Rigsby and Sarah had the side story of the night as they attended a child birth class. Rigsby was freaked out by the childbirth video... and he works homicide! Can't really blame the guy, though.

As over the top as the instructor was, she made me laugh. Unfortunately, she reminded me a bit of the instructor when I took a similar class. I kept looking at my watch counting down the minutes until I could make my escape. It made me feel for Sarah and Wayne all the more.

Wayne's marriage proposal was not a surprise but I thought even more highly of Sarah for turning him down. These two aren't in love but that doesn't mean they can't be good parents. Did anyone else notice how relieved Rigsby looked after she left?

Although he had very little screen time, Cho still delivered the best line of the night and it was only one word:

Grace: You know kids used to call me Bracie Gracie because I wore braces until I was 17. What did people call you?
Cho: Cho. | permalink

How can you not love Kimball Cho?

So do you hope we see Erica Flynn again? Do you think Lisbon was simply irritated or actually jealous of the temptress' pull over Jane?  Not one of the best episodes of the season but definitely an entertaining outing for The Mentalist.
