I didn't expect the second twist!
I was expecting a science fiction drift, which was confirmed for me when gennadiy is sprayed by that strange liquid...something supernatural, or a science fiction version of radioactive contamination, had to happen!
I totally didn't expect the Traktor appearance. This drifted your story to a sort of serial killer - horror, like a Halloween or Friday the 13th in Siberian disguise.
In the end, thus, it could be the origin story of a new superhero!
