The husband comes clean and tells the team that he was protecting his wife from a man named Wyatt Brody. Jonah explains that 5 years ago he and Wyatt stole $20,000 from a Western Union and if he didn't come up with Wyatt's half of the money, Wyatt would take it out on his wife and son. He paid Wyatt off but he still wanted more and was coming after Kara and the baby anyway. This was when the plan to get her out of the area and in hiding went into play. The twist to the whole thing is they were hidden, but an old boyfriend of Kara's named Steven O'Malley, who abused her, was trying to find her as well.

This episode had a good twist with having someone not even related to the case as the one who did the actual kidnapping. Another great episode. Too bad the show is ending after this year.
