Possibly Nicky Jr.? He was essentially he head of the family with his brother incapacitated and the father incarcerated. Maybe he conflated Sr. and Jr. when referring to “boss”. The stress of managing the blood family whilst carrying the mantle was probably high. She may have thought he had too much going on in the streets and getting stretched them with the familial responsibilities which would include her. Could be Phil too. I know it was reported that she cut Phil and his mother off after becoming a witness but I think the hatchet was buried the older she got. Pretty sure he snuck into town to see her when she was dying.
