Wow. What a strip! It makes me sad to see V headed this way, but I suppose that the seeking of ultimate power does come with a price. Compare this strip with this earlier one if you have any doubt that V has completely changed character.
I'm pretty sure that we're not seeing V's descent into A) evil, or B) lichdom.
What we're seeing is just how vital Roy is to keeping the party together, and how badly things are falling apart without him.
I'm not saying I think everything will go back to exactly as it was when he returns, or that there won't be consequences, but I'm betting a lot of what's gotten shaky in terms of party actions and interactions will firm up again.
