Now there was a truly explosive runes quality strip! Way to go , it's nice to see a villain of any true scale get what was coming to them.

As far as ramifications against V in further strips, it would be completely unlike V to have not considered all aspects before eliminating a character with such a large amount of political sway. My largest fear is that V has gotten so self enamored that S/he intends to merely deal with an attempted arrest or similar problem with a truly misguided use of arcane power.

Last bit of food for thought is does a pile of dust constitute a being? I would say that the proficiency has not been fulfilled, only one of the four words was spoken to a person.
