This is a fantastic story. I've read a few where Harry has a disability of some type, but they are all... I don't know, maybe too made-up. From what experience I've had with disabled people, this just feels right.
Keep it up. I have to admit that I'm really looking forward to whether you do a Goblet rewrite as well. I think It'd be a fun read to see how he deal with a Veela nearby. Also to see what your take is on whether Dumbledore would try to stack the competition in Neville's favour.
