June Something - Day 19

Day 19: What is something that you associate with a character in fandom, but aren't sure if it's canon or fandom?

Oh, so I generally am extremely confident about whether something is fanon or canon – to the point where I may be wrong, but I'm not hesitant about it. I'm just SURE it's the answer. (I of course admit my mistake when I'm shown or discover I am wrong, but until then I am 100% positive I am right.)

For an example, I was doing a cold read and there was something about one of the characters cooking, and I made an observation that people always had that character cooking, but it was a bit weird? Because he was like, the second son of a sect leader, it'd be a bit similar to royalty, wouldn't it, why would he know how to cook? And I just assumed it was fanon. And then someone screencapped the bit in the book where that character cooks for me, and I was like, okie dokie then, I was 100% positive that was fanon, but now I know that it's canon, so I'm 100% positive about that. *shrug*
