Plot hole: When Ethan meets the Secretary in the car, he tells him that Hendricks was seen leaving the Kremlin with the nuclear launch device and deduces that he is Cobalt. The Secretary then gives Ethan the flash drive containing his mission, which Ethan reads on the train. Ethan then tells the rest of the team that - according to the mission - IMF believes that Hendricks is Cobalt and was seen leaving the Kremlin with the launch device - hence why he needs to buy the launch codes from Moreau. How could IMF have known about this information to put it on the drive, given that Ethan just told the Secretary in the car?Brad
Trivia: The number A113 (which appeared in Brad Bird's previous films The Incredibles and Ratatouille) makes two appearances here. The first is on the side of Hanaway's ring in the flashback sequence, and the second is verbally as Ethan's agent ID that he recites through the phone after he escapes from the hospital.

Trivia: The language spoken in the video by Kurt Hendricks (in the IMF section of the train) is not Russian, despite the eagle and nametags in Russian, but Swedish, Mikael Nyqvist's (the actor portraying Kurt Hendricks) native language.
Question: What's The Fog's angle? Why does he tell on Ethan to Sidorov? Ethan intended this so that Sidorov would later find him. But as far as The Fog is concerned, what does he gain?
