Merle Callahan’s Brutal End
The season’s most anticipated death came when Kyle McLusky finally confronted his tormentor, Merle Callahan, the Aryan Brotherhood leader who murdered his wife Tracy. After Callahan turned himself in at the police station—thinking it would protect him—Detective Ian Ferguson secretly removed him from custody and delivered him to a rail yard.

There, Kyle unleashed his rage, shooting Callahan first in the legs, then the head in the most torturous way possible. Jeremy Renner explained to Entertainment Weekly that it was crucial for Kyle to be the executioner, telling the outlet that this was the only path toward healing after Tracy’s death.
The scene ended with the McLusky brothers embracing—a rare moment of tenderness Renner fought to include, giving audiences “something good” after the season’s darkness.
Kevin Jackson’s Tragic Prison Death
Kevin Jackson, a prison guard and Bunny Washington’s inside man, died during a chaotic prison riot while smuggling a burner phone to Raphael. When Warden Nina Hobbs lifted the lockdown, violence erupted instantly.
Roberto, a Colombian cartel member, fatally stabbed Kevin, who later collapsed in the infirmary and bled out in Cindy Stephens’ arms despite her desperate efforts to save him. The death was particularly cruel as Kevin had been told earlier it was his last day at Anchor Bay prison—bitter foreshadowing of his fate.
The Diner Attack Massacre
Callahan’s final play involved sending three gunmen disguised as riot police to attack Don’s Diner, targeting Mike, Kyle, Ian, and Stevie. Mike killed two attackers immediately and captured the third, Billy.
During interrogation, when Billy refused to reveal Callahan’s location, Mike coldly executed him to ensure he would never return to harm his family. The brutal act solidified Mike’s reputation as someone willing to do anything to protect his own.

What’s Next for Season 5?
The finale may have closed Callahan’s chapter, but Kingstown’s troubles are far from over. The Colombian Sicario escaped after killing Bunny’s interrogators, setting up a dangerous threat for the Crips’ operations. Meanwhile, Kyle must now raise his baby alone without Tracy, and his future in law enforcement remains uncertain.
With the cartel still threatening Nina Hobbs’ family and Mike dealing with fallout from the gang war, Season 5 (if renewed) promises even more chaos for the McLusky brothers.
