In the aftermath, she thanks him and his face gets about five percent less scowly for a moment as he lets her know t'warn't nothin'. Then he orders Dixon to find out who threw the bomb.
Up in Savino's office, Hayes already knows: it was the Milwaukee mob, giving him a warning. Savino promises to get the mob off Hayes' back if Hayes sells to him. Hayes agrees and Savino heads right over to the union office to work out a deal with Cornaro, enticing him with all the money he'll make once Savino expands the Tumbleweed the way he wants.
Ralph grills a Blue Note waitress who saw Estelle with the white guy Kovacs was talking about and so we know it's obviously either Randall or his son Terry, and that's before Jack discovers that Estelle was getting monthly $500 deposits in her bank account. That would seem to make it Randall, right?
Well, that's who the Lamb brothers are going to see, so they can ask him why he was giving her money every month and why he was spotted with her at the Blue Note Motel. They do this in front of his wife, but that's only because she ignored the Lamb brothers when they asked her to leave so they could talk to her husband privately. Randall confesses that Estelle was his daughter. Now his wife decides it's time to leave them in private.
Elsewhere, a couple of thugs do an almost comically bad job of trying to rub out Savino in a parking garage. He manages to escape with only his car freshly ventilated.
Jack and Ralph quiz Randall about his daughter on the (correct) assumption that having a kid with his "colored mistress" could end him, but Randall insists that he was going to be coming clean about to his wife and kid. He was paying her for her tuition at college, where she was getting straight A's. But then they get called away on Savoy-related business.
