Ahahaha - no, my dear boy. I have never desired the Grail - wouldn't dream of it, in fact!

[Which, surprisingly, was the truth - the grail was just another variable in the Equation, and he had little to regret about his life. Those few regrets that he did have, well...he wouldn't do something foolish like attempt to change them.

There was no changing the past, after all.]

I despise Mages, after all. Of course I would happily participate in destroying their hopes and dreams!
