The Exercise of Vital Powers (Bogus Script) by J. Michael Straczynski "AKA, the one where G’Kar has a sex change and then proceeds to sleep with Londo. (No, really.)"
Many thanks to Avelera for typing it up for us. I am posting that link for a few reasons.
1) It really does need to be spread around. It's some serious crack, people. Mentally scarring crack.
2) It further proves why you should never mess with the producer, writer, and psychologist major. Really, that's a bad idea right there. It's so insanely cracky you can't quite believe it (that line on conquering? So scarring. And not a good JMS script), but has just the right amount of believability that you can't discount it.
3) Incredibly scarring mental images aside, it's a pity that wasn't the true script, if just because it's a really good, respectful, and serious portrayal of a sex changed transgender character. Part of the reason it was on the believable side is that JMS did original plan a transgender character who was one of the main characters: Delenn. He had to nix the idea (not because of pressure from the studio, but because of issues with making the androgynous male Delenn believable due to the build and voice of the actress) eventually, but I've always kind of wished they'd been able to go through with that plot. It's totally not the first time he's given old plot lines to new characters either. IT MIGHT HAVE WORKED. (Except that this is LONDO AND G'KAR we are talking about. Which makes this one of the most horrifically scarring afterglow scenes in existence.)
4) The head writer of the show actually wrote in a slash crack-pairing fade to black sex scene. Not that he hasn't written non-crack-pairing femslash fade to black sex scenes before, but still. You have to appreciate a writer who will crack-pair his own characters. My eyes. X_X DO NOT WANT THAT MENTAL IMAGE, JMS.
I'm just going to go bleach my eyes now. Enjoy! *mutters about the all six line*
