My original fiction story finally took off, in the sense that I spaced out the other night at dinner because a scene suddenly started happening in my head and I was distracted by considering the details of it. Where it was, where it fit in the overall plot, what the point of view character was up to, and so on. And today & yesterday I've been writing it. This is always a good moment for any project.
Cracktastic plot idea: Core 4 presented with a group marriage scenario, whether because of whacky demon hijinks or sudden dimensional shift. There's Neena's classic "Last Resort", but that's not quite what I want. I'm thinking only Core 4, set it season 4 or earlier, and all four of them are out of sorts with the idea. Perhaps swap them right into a dimension where they discover that their counterparts are happily set up in a typical group marriage and they've got to blend in. Hijinks ensue, probably mildly angsty ones for a while. Ends in pr0n, in the best fanfictional tradition.
Or you could have one character, probably Xander, from the parallel universe, presented with the three weirdos from the Sunnydale that we know. There needs to be some forcing function to jar the characters out of being able to continue in their usual ways. That would definitely be angst.
Dammit, somebody resurrect the BtVS kink meme. Make it BtVS/Angel only, no RPS stuff so the writers who object to RPS on ethical grounds will come back and provide the majority of the fills again, and … I'll catalog the responses for you or something. Yeah, I know, I know, I should do it. Shut up. Or talk me into doing it. One or the other.
