Never the Bride

S1, E3: Treena Morris is a con artist. Her particular skill: making men fall so crazy, head-over-heels in love with her that they'll do stupid things, like hand her a bag full of illegal conflict diamonds, and trust that she'll put them in the safe. Her current husband/mark is just that gullible. Unfortunately for her, before she can get away with half the diamonds, the Feds bust her. On the plus side, she's got more than enough dirt on her diamond-smuggler husband to make a deal. Mary is understandably disgusted when she's told she has to help this woman get a fresh start. She's even angrier when Treena gets engaged to one of the wealthiest men in Albuquerque, allows her engagement photo to be put in the paper, and refuses to call off the wedding despite Mary's warnings. Now Mary has to keep Treena safe from angry diamond smugglers and keep Treena's fiancé safe from her.
