Weather. Rohrer chases down Mulder and in the ensuing scuffle Rohrer is electrocuted. Mulder is then taken into military custody and put on trial for Rohrer's supposed death. Eventually, Mulder breaks out with the help of Alvin Kersh, and with Dana Scully, headed to New Mexico for a final confrontation with the Cigarette Smoking Man, whom he discovered was still alive. Doggett and Monica Reyes went after Mulder and Scully to warn them that the conspirators knew where they were. Rohrer, alive and well, followed, intending to kill them all (including the Cigarette Smoking Man, who had long since outlived his usefulness to the conspiracy). However, as he approached Doggett and Reyes in the New Mexican desert, Rohrer died from exposure to magnetite.

Spender and was formerly married to Cassandra Spender, with whom he had a son, Jeffrey Frank Spender. Diana Fowley is revealed to be a subordinate of his; together, they escape the annihilation of the Syndicate. His confidence in Jeffrey falters after a failed assassination attempt and later on Jeffrey's betrayal, he confronts his son and apparently kills him. The episodes also presented further evidence suggesting that he is Mulder's father. Eventually, Fowley also splits from him, which leads to her
