Under interrogation the injured Costello proved "willing" to make a deal. Since there was already circumstantial evidence pointing to Costello's contacts it proved relatively easy to get Costello to give up Sullivan, Barragan and his FBI contacts in return for a deal. Billy suspected that they were just the tip of the iceberg, and only revealed because they were now compromised. Dignum agreed with this assessment. From what he had guessed and learned from Costello, Billy felt certain that Costello had been recruiting kids, and that in depth investigation in Southy would be required to find any more leads.
Dignum now told Billy that he was replacing Queenan until a new captain was appointed, and that Billy now worked directly for him alone. First priority, following up any loose ends and becoming familiar with Queenan's list of informants. No mention of promotion though. Never mind, Billy now had the ordeal of meeting Maddy's relations and their marriage to arrange before Billy Costegan III was born.
