Thank you. Sometimes, love for a character can lead one to shy away from their darker sides - I mean, it's not a coincidence most of my B5 fic featuring these two is set in season 4 and 5, not counting the drabbles. But the challenge to write specifically about this timeframe and this "missing scene" made it possible to adress said unsavoury aspects, because this episode is arguably Londo at his darkest (not because of Refa, because of Vir), and Dust to Dust was where G'Kar hit rock bottom.

I've often wondered just how often Vir enters G'Kar's mind, if at all, so this was interesting.

We absolutely have to guess, because you can interpret canon any way between "only if he has to" and "often". Londo says in Rock that "he (G'Kar) trusts you as much as it is possible for him to trust one of us" because of the Narn rescue railroad, but that is a part of Londo's charade to convince Vir, so it could be true, or it couldn't. There is no way of knowing whether or not G'Kar would have gone to Narn if Londo hadn't contacted him earlier and if Vir's approach really would have been the first thing he heard.

And the aftermath of Dust to Dust was my favourite part to read; what G'Kar remembers as well as what he doesn't. That's a subject I'd like to think on further.

Pray do, in fanfic or meta, I'd love to read it either way. It's, as Andraste once put it, the white elephant of the relationship, the thing they never talk about, although as we know from The Very Long Night of Londo Mollari, it's still on Londo's mind. As for G'Kar: when Andraste saw Dust to Dust for the first time, she startled me with her interpretation of G'Kar crying at the end of the beating up/mind rape/revelation sequence. Previously, I had always interpreted this as G'Kar crying about what his father (i.e. Kosh) told him, the entire "many will die" etc., the necessary sacrifice. Andraste, however, saw it as G'Kar crying he realizes what he's done, what he's capable of doing, and that this shattered his self image as a good man.
