Ok, hypothetical scenario:

Putin’s kickin’ it at the Kremlin, looking at old maps and catalogs for table-lengthening products, the usual; let’s say it’s tomorrow a bit before lunch time. Phone rings, it’s Luka and Pringlecan prank calling him from a burner. Anyway, after establishing that his refrigerator is running, and the boys laughing and making rooster noises at him, Vladka loses his shit like he always does. But this time, that cerebral AVM he’s had since birth, it just can’t take the pressure, and - pop. He mutters some stroked out gibberish and falls out a conveniently placed open window, splat.

What happens in Russia? Does someone take power or does it devolve into a struggle? Non-credible answers only, plz.
