Oh, I'd be interested to know! I'm not likely to encounter the series otherwise, as i don't read super-widely, so. Anyone else who keeps reading this thread is likely to get spoilered then, but that's on them!

I figure I'm going to have it be not particularly deeply plot-relevant, and it's been going on since a traumatic injury when the protagonist was a child, and I'm undecided on how severe it is but I do think I'm going to resist having him find a miracle-cure for it at any point-- I haven't nailed down the plot but I think it's going to be more that it's less bad when he's not under stress, and if he can trust the people around him then having a seizure is not as horrible.
