Director Langston Graham was the direct superior of agent Sarah Walker, and assigned her to follow-up on Bryce's theft of the Intersect by sending her to Burbank to track down where he sent the data. Little personal information about Graham has been established, other than that he arrested Sarah's father when he conned the wrong people. The details of the arrest and later release of Sarah's father have not yet been revealed. During this event, Graham cornered and confronted Sarah while attempting to recover money her father left in the event something happened to him, where he was impressed by her skill with knives and took her under his wing. Graham is one of a few people who knew Sarah's real name, (from her birth certificate) as well as the series of aliases she used growing up as part of her father's con jobs. It was Graham who first gave her the name "Sarah Walker."[14]
