The series finale, "I'm Not Leaving," ended on a characteristically ambiguous and chilling note. Ray, having attempted to retire to a quiet life in the country, is confronted by two young thugs looking for trouble. The screen fades to black just as Ray breaks the fourth wall with a menacing grin, suggesting that while he tried to leave the life, the life—and his violent nature—would never truly leave him.
Discussions within the fan community suggest a preference for the show ending at its peak rather than being "slogged into the ground" with unnecessary additional seasons. 3. Current Availability and Legacy mr. inbetween season 4
