So I read a story a little while ago where Sam and Dean first meet, maybe they aren't related. Sam had a medical alert bracelet for epilepsy, he wouldn't have full blown seizures, he would just kind of zone out and tap his fingers I think. It turns out that he was actually having visions when this happens but he of course doesn't tell anyone that. I'm sure Dean finds out but I don't remember much more than that.
I've looked under every epilepsy/seziure tag in a couple different communities but can't seem to find it. Can anyone help me out? Please?
