El fumador
Mulder and Scully learn of reports of rebel aliens burning doctors who were working on Cassandra. After they locate her, she informs them that the aliens are here to destroy all life on Earth and that she is a successful alien-human hybrid. The Smoking Man reveals everything to Diana Fowley, who agrees to help him and betray Mulder. Fowley forces Mulder, Cassandra, and Scully to go to a CDC facility at Fort Marlene. Meanwhile, the Syndicate meets at a check point, expecting to be taken away by the Colonists, who are preparing for invasion. They are met, instead, by the alien rebels, who incinerate them all, including Cassandra. The Smoking Man and Fowley manage to escape. Jeffrey Spender is then purportedly killed by The Smoking Man. Several months later, an inscribed metallic artifact is found on a beach on Africa's Côte d'Ivoire. Mulder examines rubbings of the object and falls into a dangerous coma. Hoping to find a cure for her partner, Scully rushes to Africa and discovers a massive wrecked spacecraft partially buried in the ocean.
