Uncle Doug is Sawyer's uncle. At his parents' funeral Doug finds him writing a letter and tells him that although he should want revenge on the man who did this, he should move on with his life and made him promise he wouldn't finish the letter. He says "What's done is done." ("The Incident, Part 1")
- The casting call described him as "Doug. Caucasian, 40s. Charismatic, soft southern accent. Strong and authoritative but knows how to deliver bad news smoothly. Deals bad news to his buddy with empathy." 
- It isn't clear if Doug is the brother of Sawyer's father, Warren Ford or the brother of Sawyer's mother, Mary Ford.
- According to the script, he was supposed to be mentioned in "Confidence Man", and he was the one who told Sawyer what Anthony Cooper did to his parents, so Sawyer knew everything and wrote the letter. This proved that the character was already conceived in Season 1, even though he was first shown and mentioned in Season 5 finale, "The Incident, Part 1".
- It is unknown if this is the same uncle that Sawyer says died of a brain tumor. ("Deus Ex Machina") But since this character was already planned in Season 1, it is likey they are the same character.
