‘Herrenvolk’ opens season four as part two of the season three finale. The bounty hunter and the other shape shifting alien, are one of many clones and if attacked, bleed green toxic blood. Mulder now tries to flee the scene with Smith in tact, as he's his only chance at saving his mother. Instead Smith convinces Mulder to, "come with me to a place... where you can see your sister." At the end of the episode, Mulder thinks he's too late as his mother still hasn't woken up. In one of the final iconic scenes, we see the character of X (Steven Williams), shot in Mulder's apartment block, but just before he takes his last breath, he manages to crawl to Mulders apartment and writes 'SRSG' in his blood in Mulder's doorway, which leads Mulder to his new informant, Marita Covarrubias (Laurie Holden.)
'Tunguska' and 'Terma' are part of a two part episode in which Mulder and Scully try to investigate the origins of a diplomatic pouch. Its contents contain a rock, but when they have it analysed, the scientist working on it makes the asumption it would've had to come from Mars millions of years ago, but that he'd like to take a further look to be sure. The agents agree. This is the first time we meet up with Krycek (Nicholas Lea) again, who insists on following the pouch. Mulder visits Covarrubias who helps by forging diplomatic papers in order to travel to Russia. Mulder takes Krycek with his when he learns Krycek can speak Russian. When they arrive at the work camp, they find that the black oil introduced in the previous season, lives within the rock.
They manage to escape the work camp but get separated. They then realise that the only way to not be tested on with vaccines or the black oil, is to cut off your left arm. Krycek meets a group of young men who see it protecting themselves and later cut off his left arm while he's sleeping and is given a prosthetic one. Mulder manges to escape without the same thing happening. When he arrives back in the United States, he teams up with Scully again and learns of a former KGB agent who's come out of retirement and travelled to America to hide the black oil by putting it back in the ground.
In the final episode 'Gethsemane,' it begins when Scully identifies and confirms the identity of the unseen body in Mulder's apartment, then leaves. She then appears before a panel at the FBI Headquarters to review her work with Mulder on the X-Files. The episode interjects between Scully talking before the panel and Mulder and Scully investigating what could possibly prove the existence of extraterrestrials, for the second time within the series. At the end of the episode Scully reveals that the Agent Mulder is dead.
Eight of the 24 episodes deal with the mythology. The other episodes deal with inbred genetic mutants, voodoo, schizophrenia, past life identities, wiccan/pagan protection spells, the history of the cigarette smoking man, a serial killer, a mythical beast – El Chupacabra and Scully’s cancer.
My favourite episode is ‘Gethsemane’ without a doubt. I saw this episode when it was originally aired two months after America which would have made me twelve. I was almost teary-eyed thinking this was the end of the duo and possibly even the show.
Keep your eyes peeled as soon I’ll be giving you the season five and six overview along with the first movie. They should be coming soon within the next week or two.
