White Knight concludes that there is someone behind the robberies and ... (more)orders Agent Six to have Rex infiltrate the three criminals. Tuck leads Rex to Tuck's friends Sqwydd and Cricket. Rex can't remember being a member of their gang because of memory blackouts which Tuck mentioned he suffered from frequently. Rex also discovers that they're being forced to work for an E.V.O. crime lord named Quarry. When Rex finally confronts Quarry he discovers that it was he who gave Tuck and the others to Quarry, who reveals the information on a Diary kept on a PDA. This causes the others to turn on Rex. Rex, suffering from a guilt trip, goes to shut down Quarry's ring, causing the others to turn on Quarry after seeing Rex standing up for them and destroying the PDA when Quarry bribed him. Quarry and his E.V.O. servants are arrested by Providence. Rex tells White Knight that Quarry had been apprehended while Tuck, Sqwydd, and Cricket had gotten away. Rex tells Tuck, Sqwydd, and Cricket that Providence won't come after them long as they don't give good reason and departs on a good note. Back at Providence, Rex informs Holiday and Six of his blackouts. Agent Six gives Rex a journal and pen for Rex to record anything that he does remember to help cope with future black outs while Dr. Holiday theorizes that the blackouts are triggered by extreme trauma.
