In Plain Sight, Season 3

Mary:
[voiceover] There's a researcher who claims he can tell if a couple is going to break up based on how they talk to each other. An ability I've had since I was five, without NIH funding. I just looked up at my parents and thought "nope." It took a six figure gambling debt, an alcoholic spiral and an FBI manhunt before they finally came to the same conclusion. It can take many forms but the worst are the ones who should have known better. The ones who rushed in, got hitched and now they don't know how to get out of it. They look like marmots, trapped in a cage.
