- Believing that Jimmy Darmody is responsible for the murder and in hiding from justice, Lucky Luciano, Meyer Lansky and Al Capone agree to betray him and divide Jimmy's share of the alcohol profits between themselves. When Mickey Doyle speaks against it they tell him that he can pay Jimmy out of his share if he wants and remind him that Arnold Rothstein still has a life policy signed by Doyle in his power.
- Nelson Van Alden signs the papers to divorce his wife, Rose.
- Nucky Thompson protects his share of the Road Appropriation Bill's assets by ceding ownership to Margaret Schroeder.
- Mickey Doyle offers Van Alden to intervene when Luciano, Lansky and Capone divide their share and make a fake arrest, dividing the money between themselves instead. Van Alden refuses.
