I'm looking for a fic. The details are a little fuzzy on this, but it involved Lois and Alt-Lois actually having been merged into one person at some point in their lives, and then split apart again somewhere in the story. Anyone have any idea? It's been a long time since I read it, and I can't remember anything else about it currently

Could it be Always something there to remind me by Zoomway?

Aha! That's precisely it. Thanks!!
