Something that has undoubtedly occured to dozens of watchers before me, but bear with me:

( Spoilers for AtA, including the season finale )

While we're talking about literary references and fantasy realms on both shows, there is a great Ashes to Ashes vid using Elphaba's song from Wicked: The Wizard and I.

I also was motivated to look for fanfic, and found, courtesy of an author I knew from her fabulous Torchwood fanfic: One flash of light but no smoking pistol.

I hadn't read Fray when it first came out, but when I came across a trade collection in England, I bought it and read it on the flight back. Fray, for those who don't know, was Joss Whedon's first excursion in the realm of comics, and is the story of a Slayer two centuries into the future, Melaka Fray. He wrote it while BtVS was still being broadcast, and there is a tiny link of sorts in Chosen, but basically you can read it on its own, without any background knowledge. I had stumbled across an individual issue eons ago which I remembered as only so-so, which was why I hadn't read it before, but when I now read the complete story, it bowled me over, and I loved it. Doesn't dethrone Astonishing X-Men as my favourite Whedonian oeuvre post-BTVS/AtS/Firefly, but only barely.
