The truth of who Bob Benson is was finally revealed on Sunday’s episode of Mad Men. My take on the revelation and how it connects to Don Draper. Warning: spoilers ahead! At The Daily Beast, you can read my latest feature, "Mad Men: Who Is Bob Benson?" in which I offer my take on this week's episode of AMC's Mad Men and what the true identity of Bob Benson (James Wolk) means for the show and Don Draper. “I used to wonder how you were so expertly servile.” On Mad Men, James Wolk’s eager-to-please ad man Bob Benson—a sort of golden retriever in an impeccably preppy suit who was always ready with an extra cup of coffee or a deli platter for a funeral—offered one of the season’s most hotly discussed mysteries, second only to whether Jessica Paré’s Megan Draper would be murdered.
