Shayn met Abby Monroe and together they came up with a daring plan to put an end to Chapple's scam which had drawn in several of Shayn's military friends, leading one of them to commit suicide. In the effort, Shayn stole a motorbike which was used in the robbery of 20 pounds of plastic explosives and blasting caps from a New Jersey construction site. Due to the possibility of terrorism, Carter issued an APB for Shayn and Abbey.
