Oh, how I'm going to miss this show. That's the feeling that hit me the moment I saw Mary Shannon in the premiere episode of the final season of In Plain Sight.

"The Anti-Social Network" picked up six months after Mary's impromptu delivery at Brandi's almost wedding and we've got a lot of catching up to do.

First off, Mary kept her baby and I couldn't be happier. Mary's so protective of everyone in her life that I could never imagine her handing off her newborn to someone else to raise. I'm certainly not against adoption but it never seemed like a plausible option given Mary's overprotective nature. I believe her 33 text messages checking on Jinx and the baby would attest to that.

My biggest disappointment was that we didn't get to see baby Norah make her first appearance into the world. I was looking forward to watching Marshall rush Mary to the hospital and what emotions would play out between these two partners. Unfortunately, all we got were some very brief flashbacks. After the suspense of last season's finale, I found that very unsatisfying.

On the up side, Mary's back at work and the banter between her and Marshall hasn't skipped a beat. But to find out that Marshall's been holding out on the office gossip? That's so unfair and it made me wonder how much contact these two have had over the last six months. 

Of course Marshall's still with girlfriend Abigail. Will that be the case by the end of the season? We'll have to wait and see.

Jinx really stepped up as both mother and grandmother but I was dismayed to hear that Brandi has continued her downward spiral and, worse, she's doing it off camera in Miami with half brother Scott. With Jinx running to the rescue, perhaps she'll drag the wayward Shannon sister back home. Everything looked so hopeful for Brandi last season. Was it all just too good to be true?

The case of the long reaching hand of the Winston Regents was fun not just because it fed into Marshall's history of conspiracy theories, but because Mary was the one to break the case. That the federal prosecutor on the case was also a former regent was a twist I didn't see coming.

Marshall's accident blindsided both me and him. If he weren't talking on his cell phone he might have seen that truck coming. He was lucky to have survived the accident and even luckier they didn't just shoot him.

The saddest part was that Ivan's mom openly admitted that her research was more important than her son. Then she seemed shocked that he wanted to go live his own life without her. It was interesting to have Mary watch this woman as she struggled with even leaving her child for the day.

Obviously, Mary's going to grapple with being a single mom and a kick ass US Marshall and I'm looking forward to watching that play out. But more than that I'm hoping that Mary and Marshall have some serious conversations before the series end about what they mean to one another and if their relationship should remain as partners and friends or if it could become more than that. 

I'm definitely holding my breath to see how this final season plays out because once it's gone, I know I'll miss it terribly. I'm already feeling the phantom pain.
