I want to piggyback on this: canon is super important, but if it isn't published or in the pipeline, it isn't canon.
I love Brandon Sanderson books, but I hated reading the authors notes for Warbreaker. A char does something inexplicable in the book and it is explained by a "fun fact" about their lives that was never written anywhere and the reader could never have known and it wasnt even relevant. It is deus ex machina. It's all made up, I know, but this is like, double made up. Fan fiction isn't canon even of the author comes up with it until and unless it's relevant and published.
It is not canon that rand al'thor puts baked beans in his shoes on cold days to warm up. It's just shit you made up lol.
Huh.
