Changes

|occupation= Sailor (formerly)<br>Prince of Hell

In 1723 Gavin is preparing to depart from Leith, Scotland to America to start a new life, when [[Abaddon]] comes through his door, having used the [[blood spell]] to travel back in time. She proceeds to kill Gavin's friend before reciting the spell to send her and Gavin to 2014. Once in 2014 Abaddon uses Gavin as leverage against [[Crowley]], torturing Gavin until Crowley pleads with her to stop.  When Gavin is healed of his wounds, Crowley reveals to him that he is his father Fergus and that they are in 2014, though Gavin has trouble wrapping his head around time traveling. During their time together Gavin learns about how his father became a [[demon]] by selling his soul for three extra inches below the belt. As Gavin begins to list off all the reasons he hates his father, one of which is his illiteracy, Crowley tries to buy his favor by at first giving him the ability to read and that if he accepts him as his father their would be plenty of more perks. Being the Prince of Hell allows Gavin to see all the possibilities and future he can make for himself once he gets back to 1723. However Crowely attempts to dissuade from going back, only telling him that "It's not a good idea" this causes Gavin to storm off and lock himself in the bedroom. After Dean kills Abbadon, Sam and Dean tell Crowley that Gavin needs to be sent back to his own time because of the ripple effect his being in 2014 can/could have caused. Crowley angerily agrees to the Winchesters demands, and only asks that he be able to say goodbye to his son. When Crowley enters the bedroom where Gavin is waiting, he magically slams the doors shut on Sam and Dean, who open the door to find the room empty. Crowley and Gavin are next seen in a field in undisclosed location, where Crowley reveals to Gavin that the ship he was about to board sunk on its journey. After Crowley gives Gavin some fatherly advice about living in the 21st century, they say their goodbyes and go their own separate ways.
