There was an episode of Teen Wolf the other day when Stiles & Derek did have a major-ish interaction and I had a moment of disconnect because "I thought that never actually happened. I thought fandom made that up!"

I remember the time I found out that Gwen was the main character of Torchwood, rather than a minor annoying character who stole Jack from Ianto, and in fact that stealing Jack from Ianto was not a thing that ever even happened. Though I'm less generous about how that misperception came about.
