query: How did Rasputin die?
passage: Grigori Rasputin
Some writers – including Oleg Shishkin, Andrew Cook,[79] Richard Cullen, and Michael Smith[80][81] – have suggested that agents of the British Secret Intelligence Service (BSIS) were involved in Rasputin's assassination.[82] According to this theory, British agents were concerned that Rasputin was urging the tsar to make a separate peace with Germany and withdraw from the war, and that this would allow Germany to transfer a large number of troops to the Western Front.[82] The theory suggests, in other words, that British agents played an active role in Rasputin's assassination in order to keep Russia in the war and force Germany to keep defending the Eastern Front. While there are several variants of this theory, in general they suggest that British intelligence agents under the command of Samuel Hoare, and in particular Oswald Rayner – who had attended Oxford University with Yusopov – were directly involved in planning and carrying out the assassination, [83][84] or that Rayner had personally shot Rasputin.[85] However, historians do not seriously consider this theory. According to historian Douglas Smith, "there is no convincing evidence that places any British agents at the murder scene."[86] Historian Keith Jeffrey has stated that if British Intelligence agents had been involved in the assassination of Rasputin, "I would have expected to find some trace of that" in the MI6 archives, but that no such evidence exists.[81]
passage: Mikhail Rasputin
Mikhail has made his reappearance and this time had allied himself with Sinister. The two were attempting to assassinate all of the members of the Rasputin family but one, so that the spirit of their forefather Grigory Rasputin may be concentrated and reincarnated in the last remaining member of the lineage. Mikhail teleported himself and his brother to another dimension that was a series of rocky caves. Not wanting to physically kill his brother, he decided to leave him in the rock dimension where he would die in a matter of weeks. However, away from Sinister for a period of time, he was able to overcome his mental manipulations and came to his senses, rescuing his brother. His final decision was to teleport to a world named The Dark Zone, a dimension from which it was impossible to return and also once entered, impossible to die in. This protected the rest of the Rasputin line from the depredations of Sinister as at some point Mikhail would have been the sole surviving Rasputin, which would then trap his ancestor in the dark zone. Colossus tried to persuade him to save himself, but Mikhail determined that it would be best for the possible problem and for his own insanity.
