Ahh this is such an interesting question and very difficult to answer, because I have a bunch of ideas right now that I'm still figuring out the logistics of, so I'm not sure if they fall into 'I will actually write this' or 'if I could ignore the logistics. . .' yet.
Definitely no such thing used to be my answer to this. S7 was a mess with a lot of holes to fill. And now. . . I want to write something set in the in-between of reckless, exploring how Hotch and Emily get together. And I probably will write something, but I'm not sure how deep to go yet - like, a one or two part thing set earlier in their relationship? A multichapter?? Start when I said in that fic their relationship started, or before? Slowburn or not? I genuinely have no idea what I'm going to do with that, and I don't want to get too tied up in it because I'm also kind of aware that it might end up with basically no audience because I feel like things set in established AUs where OC kids are a significant part of it are kind of niche, and I'm not the kind of superhuman who doesn't care about that unfortunately lol.
I want to write something about Emily helping Hotch out after Foyet's attack too - the fact that she's driving him to work and back and walking him up to his apartment suggests she was the one providing practical support while he recovered and I love the idea of that. But it's intimidating - the research for the medical side combined with the way the show glossed over it, plus it's an area where I really notice I don't always know whether the words I would use are the same words they would use. . . That one just freaks me out for a bunch of reasons, but I would like to do it.
Also various Foyet-arc reimaginings have always interested me. It's one of those things that changed everything, and it would take just the tiniest tweak for the whole thing to go a completely different direction. So maybe. But again, a lot of factors, and it scares me.
Basically my brain wiring has gone haywire and I struggle to be like 'I'll write a lil oneshot exploring X', so as soon as I have any sort of normal sized idea, I freak myself out. I just published a oneshot of a normal sized idea to try and solve this problem, and I had to wrestle with myself to just end it there and post it.
