Events worked out quite well. Costello's FBI minders took the bait, and after checking Billy's known background came into the SIU to demand Billy's arrest. Ellerby and Queenan, among others, took great delight in escorting them to the cells on charges of conspiracy and treason. It might be difficult to make all the charges stick, but a court trial would create such a stink that the FBI, hopelessly tarnished, would be forced to clean up it's act.
Sullivan, who had been kept in the dark over the full evidence and let out on bail, was tried at the same time. Following Barragan's confession and a study of Costello's payments, Billy realised that Sullivan had been recruited by Costello when a juvenile; this was confirmed by investigation. On hearing Billy's testimony in court, Maddlyn realised that she had not exactly been lied to by either Collin or Billy, but she did not know either as well as she though she did. She had thought Billy a crook, he had sort of admitted it, but she knew he was really a good person. Now she knew why he had been in such a near deranged and distressed state. Collin on the other hand was revealed as an almost pathological liar who might well be rotten to the core. It was time to see Billy before he left the court and explain that he was going to be a father.
