@GodHoward It's pretty clear that the aftermath of WW3 and horrors of the post-war era played a big role in shaping Kashchey into who he is now. However, as important as these might be, they're not that relevant. What really matters here is the Snake's true identity, and let me tell you, when Valery and Talulah find out who he really is... let's say it will be painful.
