James Haggerty was one of the first two Men of Letters to enter the Bunker, along with Peter Jenkins. In stark contrast to Jenkins, upon entering the Bunker, Haggerty had a more apathetic view of their assignment, remarking that the Bunker was a "dump." Six months later, Dorothy arrives looking for help in killing the Wicked Witch of the West. During their research - the Wicked Witch frees herself of her bonds, and takes possession of of Jenkins, forcing Haggerty to kill him. As he makes his way to the lab to assist Dorothy, he sees bright flash coming from the room, but when he opens the door he finds the room empty.
Haggerty keeps Dorothy's file open, and spends his career until his retirement, trying to find a way to save her and stop the Wicked Witch. At some point, he learns that poppy seed extract can harm the the Wicked Witch, and goes about making a deal with a fairy to procure some. It's that poppy seed extract that is used by Sam, Dean, Charlie Bradbury and Dorothy in 2013 to fight the Wicked Witch in the form of poppy seed bullets.
While searching through the Bunker's archives on angelic grace, Castiel finds a confidential file written by Haggerty about the Men of Letter's belief that with enough grace of an Angel extracted from a former vessel, the grace could be used in a tracking spell to find the angel. However, while the file described the spell and the extraction procedure, it also noted that the Men of Letters were never able to test the theory as they were unable to find someone to extract the grace from. His files on the Inner Working of Angels included his invention; the Grace Extractor.
