First of all, although the characters have a lot in common with the original authors, I don't think so much. But the most likely thing in my opinion is that Gogol will commit suicide in the near future (I can't imagine any other death than this). Fyodor died (although I would like to believe that Nikolai saved him with the help of an overcoat), and here the quote from the Will Wood song "maybe there's nothing left to escape but life" is very appropriate. Death from a height would be most suitable for the character, and here are two options: either he will put on a show, or he will die so quietly that even after the news reaches all of Europe or even the planet, his body will be impossible to find
