Meanwhile, Arlinsky returns to the mountains with Mulder, but they find that most of the expedition members have been shot dead. The sole survivor is a man named Babcock, who reveals that he has saved the alien corpse from theft by burying it. Together, the three men bring the corpse to the United States. There, Mulder and Arlinsky perform an autopsy on the corpse, believing it belongs to a genuine extraterrestrial. After Mulder leaves to meet with Scully, a mysterious assassin, Scott Ostelhoff, arrives and kills Arlinsky.
