On the final episode of In Plain Sight, Mary has an unexpected family reunion and she and Marshall discuss their future. Changes take place around the WITSEC office.
Mary must prevent a drag queen from reverting back to his old ways while Marshall is brought into an undercover sting operation where we see a whole new side of him on In Plain Sight.
After six months of maternity leave, Mary returns to work to protect a witness from a corporate giant while juggling mandatory therapy and being a single mom on the season premiere of In Plain Sight.
Marshall: You are in a different kind of mood this morning. Mary: Actually, I'm in a really good mood. Which is kind of weird considering where I was 48 hours ago. Then I had a witness off herself and, like that is not bad enough, I've got to play second fiddle to a knucklehead like you. Marshall: Thanks for lumping me in with kidnapping, attempted rape and suicide. Can't tell you how much that means.
