Sorry, work is insane right now, so I'm going to put all my praise in one comment :)
This was a brilliant end to the series! I loved how the ending tied back to the !Wishverse Giles, in that he just believes it has to be better :) So many twists and turns, you had me anxiously waiting for each chapter. I only wish my iPhone wasn't so brainlocked when viewing LJ - or I would have tried to comment sooner.
Well done! And I can't wait to see what everyone comes up with for Drunken Giles!
