What new insights does the reader get into Squizzy Taylor’s character in this chapter?

The theme of violence re-emerges when Charlie arrives at Squizzy Taylor’s to learn of a coming eruption in tensions between Squizzy and his violent rival, Snowy Cutmore. In addition to violence, the themes of power and masculinity also arise when Charlie sets off to collect Squizzy's debts for the first time. Though Charlie is initially frightened and uncertain, he learns that he can intimidate the greengrocer by threatening to send Knuckles (implying it will be a violent visit) over to collect the money. The cash in Charlie’s hands fills him with boldness, and he uses the same tactic on with his remaining collections.
