Wing!fic -- I'm sure you're all tired of hearing about it, but this is my current WIP. I'm working on the first fic in the series which is taking forever because it's so very important. It is all foundational. The subsequent stories will mainly be shorter and some will be ficlet codas for episodes or missing scenes. Just ways I can weave the story into current canon. I have a codas designed to end 5x02 and a missing scene for 5x03. Those will be shorter. I have some longer, more intense fics that will happen throughout, though., and a bunch to finish and post for S4. The fics I have planned some are gen and some are het, and I'm bringing in so many characters. I'm so happy with this pet project which is why I can't seem to stop talking about it. I think I am half way through this first fic and I am so glad about it. I want to move onto the other stuff, LOL. I have some funny Sam and Dean, Dean and Cas, and Dean and Jo stuff I want to get to, grr.
Bobby!fic -- I came up with this idea the other day and it won't leave me alone. I keep hesitating because it could easily become of of those fics that really feels like sub-par fanfic, and I'd rather it not be, but if I can make it work it would be interesting (to me), I think. Set in S5. A bunch of ideas came together to create it: Dean poisoned with something that changes his mental state, Sam working on rebuilding his relationship with Bobby and Dean, Bobby working through his own limitations and what's happened to him, and an exploration of why Bobby and John split and how the mistakes of the past can be avoided in the present if one really tries. I think it could be layered and nice, without villifying anyone, but while also exploring a lot of issues.
Amnesia!fic -- I still want to do a fic where Dean gets amnesia. Just because. I have a good part of it figured out, but I may wait longer on this one to see where canon takes us. I was originally going to have this set in S4 and I may keep it there, but I could adapt it to S5 if I wanted. Whenever I set it, I still want to keep a part where Dean thinks Sam is a monster hunting him.
Under the Blood Moon (Dean POV) -- I have a short fic planned to show what happened with Dean while Sam was trapped in an alternate world from one of my own recent fics. It's not exactly a sequel, and it wouldn't nearly be as long. (Who the heck wants to read a fic where Dean is in the hospital for 3/4 of it? Not me. I don't do H/C, really.) But I'm eager to explore what happened between Dean and the alt!Sam. I didn't really go much into it in the Sam AU, and I did that on purpose. It'll be en entirely different fic and that's fine.
I have a couple of shorter, not quite as plotty fic ideas bouncing around, too, but those aren't developed yet. Still, this list isn't very long. I hate feeling like I have a fic list a mile long and it got so out of hand when I was writing SG-1. I'd love to finish these and not have them waste away in nowhere land.
