Uh, welllll, now that you're mentioning it. I still have a story concept in my "plots" folder. In that story, Snape ends up in Middle-earth and I finally pair him up with Gríma. I totally ship them - they have so much in common. The looks, having been seduced to the evil side at some point, the hopeless obsession with a woman they could never have... Should I tell you in ten years, when I might have the fic finished? ;)
