Back at SIU surveillance Control, three parties were not slow at guessing what had just happened :
Sullivan, who now launched into damage relief overdrive to protect his own neck.
Barrigan, who realised that Sullivan could be "The Mole", no wonder he had been able to help him so much to become a detective; did Sullivan know about Costello's FBI double dealing?
Dignam, who after watching the start of Sullivan's damage relief overdrive overcame his professional secretiveness, grabbed Ellerby and said "A Word In Private, NOW".
Sullivan's damage relief consisted of confusing the issue. He ordered two operatives to shadow Billy and Queenan, while the other two were to stay in the car and monitor the gang. Sullivan now needed time to think. He made the excuse of seeing Ellerby. Good thing that Ellerby was now in an office getting the raw end of Dignam's tongue. It gave Sullivan the chance to text Costello with "Q left B with B.C". Sullivan would also have liked to add "KILL THEM", but the danger was too great since he was dependent on the police tails to get at them and any killing would be in "full view". Chances were that more than just Dignum would put two and two together. Best to get out of this with fast talking and try and save the Queenan's life, whatever Queenan might reveal.
Dignum had been filling Ellerby in with "The Facts of Life" as far as Billy was concerned, as well as with what he thought about Sullivan wrecking the undercover operation. He demanded that they both needed protecting and Sullivan should be dissected, though there was no chance of Ellerby agreeing to his "Teacher's Pet" even being suspended. However, when Ellerby emerged he brushed Sulivan aside and went to the control desk to give orders.
