Alex is a Greek fisherman who takes in Tom Chandler and his family while they were living in Greece. His daughter, Cali, was dating Chandler during his time in Greece. He eventually found out the man staying with him was the captain of the Nathan James. When Giorgio Vellek stole the fish Chandler and Alex caught, or 'collected their tribute', they decided to retrieve the boat at night. Later on, the boat they retrieved was set on fire, and Alex was discovered dead from suffocation due to the smoke he inhaled. Chandler discovered Moose, Giorgio's enforcer, was present when the arson occurred.
Later, when raiding Giorgio's island with the Nathan James crew, Chandler responds to Giorgio's threats by asking if Giorgio is going to kill him like he did Alex and Moose. Giorgio responds by revealing Chandler's own acts of brutality to his crew.
