When a lead from CTU led to Cofell, Jack Bauer called his office to arrange a visit. Nancy answered the phone and Jack claimed to be an old friend of Cofell's. She told him that Cofell was in a meeting and leaving immediately afterward at 10:00am. Jack abruptly hung up the phone and traveled to the office. He phoned back as he entered the lobby and Nancy passed the message on to Cofell as he was entering the elevator for the parking garage. Moments later, Jack arrived on the floor and overheard her telling Lewis that Cofell was on his way down. She explained to Jack that Cofell had just stepped into the elevator, and Jack took off running down the stairs. ("9:00am-10:00am")
Nancy was the name Cofell referred to her as. However, later, she referred to herself as Tracy. The actress playing the role is named Tracy. It is possible that Ted was mistaken in her name, or that the actress herself simply had a Freudian slip.
