This is very good. I loved his reaction to Buffy returning, and his retreat from Ellen into his cold place, and her spotting it. Lots to love here. The St. Anthony prayer and Ethan's acid scar.

I'm a little concerned about Giles having streaming tears and Willow holding his hands. I don't know if Giles would cry so openly and make no attempt to hid it. If he did, I picture Willow racing to embrace him.

But that's a minor opinion difference over a long piece of very good writing. Thanks for sharing this. Looking forward to Buffy's arrival.
