Marcus was the most conscious of brothers. He could tell you about his grandfather the Garveyite; about his mother in St. Louis who had raised her kids alone while working as a nurse; about his older sister who had been a founding member of the local Panther party; about his friends in the joint. His lineage was pure, his loyalties clear, and for that reason he always made me feel a little off-balance, like a younger brother who, no matter what he does, will always be one step behind.
