I'm glad you liked the story. I miss Mary/Wilson, too. I've hardcore shipped them since I was nine years old

As for the fandom, it's mostly tweens doing "This is what the will be like in Season 34" fics. There's some decent stuff, but you have to do a bit of digging. If you're interested, go over to
ff.net and poke around. That's the only real place to find 7H fics.
