I also fully believe (in a tinhat way) that it was actually at least partly about Nico as well as the book it's actually based on. But, well, I'm a tinhat on that (then again, if I admit it, am I or am I actually seeing how I might be wrong?).

And then there's my extremely weird theory that really only works applying to fandoms that Jack is Lou and the Doctor is Andy Warhol (which might make John either John Cale or one of Lou's wives/gfs/bfs and Ianto has somehow become Candy Darling in my head because of this... huh).
