The Mentalist invited fans to a "Wedding in Red" this week, as Rigsby popped the question to Grace and the two had one of the quickest engagements on TV.

Below, TV Fanatic Christine Orlando is joined by The Mentalist fans Foresti Purge, @nehakatti and Nerwen Aldarion to debate where McAllister ranks on the Red John list and if Grace's choice in wedding attire was just a little too weird.

-------------------------------------------

What was your favorite scene from the episode?

Forseti Purge: When Jane ruins the wedding the first time. It's hilarious in a dark, sociopathic way, kind of like drug dealers going to twelve-step meetings to peddle drugs, but this is why we like Jane. IRL he'd be living in a supermax now, but his selling point is that he couldn't care less about limits, and this scene shows us just that.

@nehakatti:  So many amazing scenes! From jane helping Lisbon with her jacket to him sneaking a peek at the wedding. But my favourite, Jane and McAllister analyzing the crime scene while Lisbon looked on. That sense of competition between them was amazing, is what I think a conversation with Red John would look like..

Nerwen Aldarion: The car scene with Rigsby and Cho had me laughing, classic fun between those two. Jane telling Lisbon he was ordained was funny too and I loved her face when he said he could marry her off in a minute (And the sexy way he said 'Don't tempt me' had my Jisbon heart pounding) Jane being the minister is probably one of the funniest things I've ever seen. I'll also admit, while I'm not a die hard Rigspelt fan I thought their wedding was very sweet, particularly watching how Simon Baker played his emotions in that scene.  I know that's like five scenes but I can't ever choose a favorite scene in my life.

Christine: There was something about the way Jane watched from the doorway asWayne and Grace got married. So many emotions played out across his face. Joy for his friends and yet there was a sadness there, perhaps remembering his own wedding and all he'd lost. Kudos to Simon Baker for conveying so much without saying a word.

McAllister's fear of heights. Did Lisbon and Jane read him wrong or was McAllister playing with Jane all along?

Forseti Purge: He was playing with Jane all along. Beware the man whom nobody fears. He may be the one who knocks.

@nehakatti: I think, McAllister, Smith and Bertrem are working on tricking Jane. He was clearly not afraid of heights even though he acted like it and now Dr. Miller's analysis might also be tainted because of that.

Nerwen Aldarion: Maybe Jane and Lisbon saw what they wanted to see or perhaps it was more about McAllister being none too willing to climb a ladder at the time. I myself don't have an extreme fear of heights but I'll climb a ladder if I have to, if I don't, well then I'll gladly pass the job to someone else. This doesn't seem to eliminate or validate Mcallister as a suspect in any way.

Christine: So confusing…in a really fun way. I have no idea if they just misread the situation or if he's really playing with them but I agree with Foresti…he could be far more dangerous than most believe.

Did you find it odd that Grace kept her wedding dress?

ForsetiPurge: Not really. Jane kept a bloody smiley on his wall.

@nehakatti: It's pretty odd, yes. But so is being engaged to a guy and never knowing he is a psychopath.

Nerwen Aldarion: That she kept it? Not really, I could see her holding on to it as a "what might have been" situation. Her choice in groom was flawed but not her dress. What I did find odd was that she just happened to have her dress in Napa. Who knew every woman carried their wedding dress with them on a case.

Christine:She must have really thought that was the perfect dress because I couldn't imagine wearing the same dress I'd bought to marry a Red John minion. Nerwen, I'm going to go with she somehow had it sent from home…but yeah. It did just kind of magically appear.

Give me your thoughts on Wayne and Grace's wedding. Loved it? Hated it? Or anything in between?

ForsetiPurge: It's an okay wedding, not bad, but not great either. The writers had stretched their relationship as far as they could, and now they've got no more story options left but to marry them.

@nehakatti: I think the wedding was amazing. It would have been perfect if Ben was there.

Nerwen Aldarion: Their wedding was perfect for them, simply and sweet. THe best part was Jane watching from the side. He never likes to display his emotions even when he was genuinely happy for them, most likely because he knew it would also make him sad. That wasn't something he wanted them see.

Christine: I think it was perfect for them. A little rushed perhaps but since I haven't spent years waiting for the moment I thought it was very sweet. But if we ever get a Jisbon wedding I expect a lot more buildup.

Where does Sheriff McAllister rank on your list of Red John suspects?

ForsetiPurge: He is my first. He always has been. As a writer, you can't plan too far ahead, and only 2 out of 7 suspects appeared in Season 1. And Partridge is a textbook Red Herring--nobody, except yours truly of course, would suspect the guy who showed up in the episode after the pilot.

@nehakatti: In the top 3, along with Haffner and Bertrem.

Nerwen Aldarion: McAllister still ranks rather low on my list, perhaps above Smithe now but still below Kirkland, Bertram, Stiles and of course my number one choice, Haffner

Christine: This one had me looking at him in a whole new light. He's a lot smarter than I ever gave him credit for and he certainly had a competitive chemistry with Jane that's I'd expect from Red John. Right now he's my number 2 guy behind Haffner.
