El fumador
Mulder and Scully arrive at the mining facility and, using the code for Napier's constant given to them by Klemper, unlock one of the reinforced doors inside. The agents discover a large complex of filing cabinets containing smallpox vaccination records and tissue samples. Mulder finds his sister Samantha's file and finds that it was originally meant for him. Meanwhile, Skinner tells the Smoking Man that he may have found the digital tape. The Smoking Man is agitated at this, insisting that he will not make a deal with Skinner and tacitly threatening his life.
