Totally know what you mean about getting back into writing in a fandom and not remembering all the details. Even more embarrassing, I do this sometimes the original stuff hearts_blood and I are always playing with - we'll abandon a project for a while in favor of another, then I'll go back and be like "...wait, how does this all fit together again? What was the name of that one guy? Crap, now I have to reread all the old stuff again to remember, just so I can write this one scene..."

And yay for writing B5 fic again! I shall have to try to remember to keep an eye on your LJ for further updates. Are you on Ao3 as well?
