Judah is an H.P. Lovecraft enthusiast, who felt that Lovecraft was literature and should be taught in school. When Sam, Dean, and Bobby learn that Lovecraft may have opened a door to Purgatory on March 10th, 1937, Bobby pays a visit to Judah, who has the world's largest collection of H.P. Lovecraft's personal letters, and tries to get some information about the night in question. Judah reveals to Bobby that a man fitting Castiel's description was also inquiring about the letters, and when he goes to show Bobby the letters he finds that they have gone missing.
