Ava, Murielle's classmate, asks her dad about the Lyman case after hearing Tommy in the lunchroom.
How did the feds not know the Lymans were stealing money?
Uncle Travis calls Matt Keefer, an FBI agent that had worked on the Lyman case, after Tommy tells them about Cathy. Keefer goes to school with Tommy the next day and tells Cathy to pretend to be Murielle in order to bait the Lymans.
Nice to meet you Cathy. My name is Matt Keefer, and I work with the FBI. I'm going to need your help.
Keefer tells Murielle to post a video online saying that she has cancer and asking her mother and father to come to her. When her mother responds to the video asking Murielle if it is really her, Murielle only replies with one word..."RUN".
Why would you do that?!
After revealing that she in is fact who everyone thinks she is, Murielle says that she had to save her parents and tell them to run. In the end, Aunt Lois and Uncle Travis forgive her and take her home. And they lived happily ever after.
