The man behind the cloud of smoke has been involved in the afaairs of the X-Files since the day Section Chief Scott Blevins assigned Dana Scully to "assist" Fox Mulder. His silent presence in Skinner's office is always a warning that the shadowy goverment attemting to discredit Mulder is again keeping an eye on the non confirmist agent. When not in Skinner's office, he can be found in the basement of the Pentagon, secreting evidence in a vast storehouse of classified materials. The tension between Mulder and the C.S. man has increased steadily as the nameless man with the pack of Morleys increasingly involves himself in Mulder's work. In "One Breath" Mulder blamed the C.S. man for the abduction of Dana Scully and came within a trigger-pull of killing him. In "Anasazi" we learned that his involvement goes back to the beginning, all the way to mulder's father. He may be responsible for Bill Mulder's murder, and his is certainly responsible for several attempts on the life of the X-Files agents. His menace may be fading, however, as both the Well Manicured man he answers to and Alex Krycek, his tool who has turned against him, threaten to bring upon him a justice Mulder and Scully cannot.
