Episodes

14.11 Damaged Goods

After being kidnapped by Nick, Mary leads him to her lock-up where the Enochian Puzzle Box containing the demon Abraxas is located. After avoiding a shotgun booby-trap, Nick breaks into the warded lockers in the lock-up until he locates the puzzle box. Kidnapping the facility's security guard Jeff, Nick places him within a devil's trap in the lock-up and releases Abraxas before being confronted by Sam, Dean, and Sheriff Donna Hanscum, who'd tracked Nick through his stolen van. After a confrontation, Abraxas is killed by Nick with an angel blade and Nick is subdued and arrested for his murder spree.

Trivia

• Mary's shotgun booby-trap is similar to the booby-trap in John's Lock-up that was seen in 3.03 Bad Day at Black Rock.
