I doubt anyone else is terribly interested in steampunk/Doctor Who watching/astronaut madness, so I don't think it's highly unlikely you'll get it. I hope you do, because I'm very interested in this plot of yours.
And that fic sounds relevant to basically every single one of my interests. Honestly, it sounds like I wrote it because Unspeakable!Remus and steampunk as well?! but I didn't write it, which is the best part because it means someone out there is basically me except...not me and that is exciting. Really looking forward to reading that, then, thanks for the rec.
