Mary's snarkiness was in rare form as she dealt with the nanny search at home and a hall of fame weasel of a witness at work.
First off the crime that drove John into WITSEC was gruesomely fascinating. They were stealing kidneys while performing gastric bypass operations. That's both criminally brilliant and horrific all at once.
How the heck do you go into WITSEC with two wives? What made John most despicable was that he never acknowledged the damage he'd done to these two families.
Mary and Marshall's reactions when they found out about John's bigamy were priceless. Mary snarked that he was the last of the hopeless romantics as he proclaimed his love for both families while Marshall called him a sociopath for believing his own delusions.
Mary was hoping for a back stage pass to witness the wives when they broke the news to them. Instead she was part of the show. Be careful what you wish for.
When Mary showed Eve the Christmas card of John with his other family, all I could think was that this guy's a total bastard. Even Mary griped that calling him out was way less fun than she expected.
John lied to these women for seven years and then acted like he couldn't help himself because they were both so amazing. Yes, and each one deserved a real husband. Instead they were stuck giving their kids the speech about Daddy making a horrible mistake but that didn't mean he didn't love them.
I never doubted that Bonnie was the caller. The girl was angry about never being able to play lacrosse again when she thought Dad had simply witnessed a crime. Imagine her anger once she realized he'd betrayed them all on top of it.
When she screamed at him, asking how come they weren't enough, I briefly wondered if Mary had had those same thoughts about her own father.
But one of my favorite In Plain Sight quotes was when Mary asked John…
Mary: Hey Big Love. It is just the two? Tell me you don't have a red head stashed behind door number three. | permalink
…because I was thinking the same thing. Now that John's separated from both families how long do you think it will be before he finds wife number three?
Back home, Mary and Mark were interviewing nannies and I can't imagine a person on the planet that Mary would trust with her daughter. As much as Mark should have talked to her first, his mother arriving was a blessing.
Mary describing Stan playing kissie face with his girlfriend to Marshall over the phone was hysterical. They were both fascinated and repelled at the same time.
How many seasons has it taken for Marshall and Mary to realize that she's his work wife? At work, he wouldn't know what to do without Mary. Life would be a lot less fun. They are the perfect pair.
But would they make such a great couple in their personal lives? Probably not, but I'd love to see them talk about it.
Maybe that will happen now that Marshall's engaged. His proposal to Abigail was unique, unexpected, sweet, and funny. As much as I wasn't sold on Abigail in the beginning, these two do make a great couple.
So do you think Marshall and Abigail are meant to last? How will Mary react when she finds out? With only half the season left, In Plain Sight continues to outdo itself every week.
