I'm not positive that we'll ever get an explanation for why Angel did the Twilight thing. I'm just hoping that we'll get some sort of idea of his reasons for what he does in the coming season.

Though I'm more interested in why practically every other character does what they do. Angel being a deluded, power-hungry idiot never seemed like much of a stretch to me. I don't understand why he turned his back on Connor, et al, and I don't understand how anybody in government would give him the slightest credence. But other than that...
