Tropes
- Bitch in Sheep's Clothing: Tanya, who appeared the supportive girlfriend and kidnap victim only to turn out to be the mastermind of the whole thing.
- Engineered Public Confession: Derek pretends he overheard Tanya and her accomplice talking to trick her into confessing to what she did as the team listens in.
- Fake Pregnancy: Tayna pulls this to con Derek into proposing.
- Hoist by Their Own Petard: Tanya left behind some of her blood at the crime scene to sell her fake kidnapping. That just gave the team a chance to do a blood test to confirm she wasn't pregnant.
- Secretly Wealthy: Derek turns out to be the son of a billionaire and thus a huge fortune at his fingertips.
- Spotting the Thread: The team unravels Tanya's lies when they see that the car trunk she claimed to have been thrown into was barely big enough to fit luggage, let alone her.
- Wham Line: At the end, as it all seems settled, Derek brings Tanya back to the field to ask her a very important question, her grinning as she expects the proposal.Derek: What did you do with my father's money?
