Sometimes I read so much fanfic that I can't remember if something is canon or not. I'm not the only one, am I? Please tell me I'm not.

So here's a thread for people like me to ask FS about those things in our fandoms that we're not sure if they happened in canon or if it's more a fandom hivemind deal. It's probably best to change the subject line to the fandom name, even if it means having multiple threads with the same title.
