Scully and Mulder participate in a raid on a group of right-wing extremists who are obviously planning an attack of some kind. Mulder has been receiving anonymous notes from someone who knows of the plan. When they stop the terrorists, one of the men turns out to be Mulder's old nemesis Alex Krycek, who claims to be the person who was feeding him information. Meanwhile, a diplomatic courier is caught smuggling a mineral-like object into the United States. Mulder contacts Marita Covarrubias of the UN to learn more about its origin. He and Krycek are soon on their way to Russia. Written by garykmcd

From Russia With Love
28 August 2006 | by (Roy, Utah) – See all my reviews

Tunguska allows the viewer to re-board the thrill ride known as the myth/arc. The mythology episodes at this point in the x-files have a lot more action and are faster-paced. This makes them all the more exciting. Plus, anytime you get to add recurring characters like Alex Krycek, Cigarette Smoking Man, Well-Manicured Man and Marita Covarrubias, it gives a certain quality to the show. The teaser for this episode is different from what we're used to. It has Agent Scully testifying in front of a senate sub-committee, letting you know that you're in for something special. If Alex Kryeck(aka Ratboy) is a character you love to hate, this is your episode. Mulder captures Krycek on an FBI raid and continually gives Kryeck a beating throughout the episode, letting the insults fly. My favorite is when Mulder tells Krycek where the level of his moral dipstick is. One things that bugs for this episode is when Mulder is getting information from Marita Covarrubias. She acts all sensual towards him for no apparent reason. Weird. Another minor annoyance is the black oil. In Piper Maru/Apocrypha from season three, whenever someone got infected by the black oil, they acted as if controlled by an alien force with a specific purpose in mind. In this episode, the people that are infected by seemingly the same black oil simply become catatonic and non-responsive, which is quite confusing. Nevertheless, Tunguska is a very fun episode which has a great final shot for a suspenseful cliffhanger.
