Before heading off to college, Deva confides in Lucas, saying with everything that has happened, she doubts she’ll thrive in a place as “normal” as college. Lucas assures her that she has time to figure everything out, adding that now he’ll always know where to find her and promising that he will always find her.

After questioning Lilith at the Banshee Sheriff’s Department, Dawson tells Lucas that she thinks someone else murdered Rebecca and made it look like one of Declan’s kills.

Bunker gets a call from Carrie, informing him that Proctor’s trade with the Colombian Cartel is about to go down. Brock overhears the phone call and demands to be let in on the vigilante-style bust.
At the Banshee airport, Proctor meets with Cartel member Loera to hand off the drugs. The deal comes to a sudden halt when Proctor opens the truck carrying his supply, only to find Carrie and Job in the vehicle.

Carrie, Job and Brock escape, and after killing Loera and his men, Proctor and Burton speed away from the scene as well.
As Proctor and Burton drive towards Banshee, Lucas barrels his car into them, sending Proctor’s vehicle tumbling off the road. Burton is knocked unconscious by the fall, leaving Proctor unprotected.

When Lucas turns to look for Burton, he finds only a pair of glasses.
Burton appears suddenly and launches an attack on Lucas. Outclassed in the fight, Lucas wins by sheer force of will and anger. He breaks Burton's back before placing him in front of Proctor and walking away. Burton confesses that he killed Rebecca because she was destroying Proctor’s empire. As Burton weeps, Proctor breaks his neck.

“No one else – Nobody ever really knew me.” - Lucas
Lucas sits with Sugar for a final drink. Also at the bar, Job tells the two men that he’s “gettin’ while the gettin’s good.” He has a parting gift for Sugar – a bag full of money for Sugar’s retirement.
Lucas gets on the motorcycle he first drove into Banshee and rides past the “Welcome to Banshee” sign out onto the open road.
“The past has kept you locked up long enough. Today, there’s really only one question left to ask yourself. What are you going to do now?” - Sugar
