Mary Reconnects, All the Way, With Her Ex-Husband on 'In Plain Sight' (VIDEO)

If Marshall's into Mary, as we all know he is on 'In Plain Sight' (Sun., 10PM ET on USA), he might be second-guessing his desire to meet her five-day husband from high school. That "double date" dinner led to Mark and Mary rekindling at least the physical part of their relationship back at her place.

Unfortunately for Mark, though, physical is all it was for Mary. She's just not ready to jump back into something more real, even if she is just the kind of amazing woman he'd love to rekindle things with.

Mark was a lot of fun as their tryst unfolded. We loved the bit where he told her he still had a dancer's body ("You're welcome"), but the best was when he stopped and asked, "What if your mom busts in again?"

"You have no idea how possible that is," Mary returned, but it certainly wasn't going to be enough to stop either of them.
