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.

HAHAHHAHAHAHHAHAHHAHAH. I actually dislike that show, but having watched the show without ever having really seen much of the fandom, this is hilarious. And really, really sad.

I bet people who haven't watched The Avengers think it's about Coulson and Hawkeye and maybe some other people.
