Why wasn't Darla in this episode? It never made sense to me why she wasn't in this episode.
Angel had been captured, but it is always possible he managed to kill Darla before that happened. After all, we didn't jump time. it's still season 3, so presumably somethings happened in the 2 years before the episode.Because it wouldn't have been as surprising to see Darla as it was to see Willow & Xander. When it comes to alternate universe storylines, the writers try to push radical changes since that's the only time you'll ever see such a thing happen. If Darla showed up, I don't think anyone would have really been all that shocked.
