Everyone, including Mulder and Scully's mother, had pretty well given Scully up for dead when she suddenly reappears at a Washington hospital. Details are scanty - the hospital can't really say how she got there - but she is comatose and on a ventilator. With the help of the Lone Gunmen, Mulder learns that her DNA has been altered and that her immune system has shut down. The mysterious Mr. X fails to make contact with him and Mulder hen goes after the Cigarette Smoking Man, ready to do whatever is necessary to save his friend and partner.
