"Stranger Things" became the must-see TV show over the summer, and if you haven't watched it by now you are sorely missing out! With the uber success of the Netflix hit came a cult like fan base, much like popular franchises, such as "Harry Potter."

Fans of "Stranger Things" are hard core, developing their own theories about the Upside Down, figuring out if Barb will ever make an appearance again (?!), and what lies ahead for season two. Much like the fans of "Stranger Things," "Harry Potter" fans are just involved, if not more. So, what would happen if everyone's favorite character from "Stranger Things" met up with one of the most beloved characters of "Harry Potter"? FANDEMONIUM!

Yes, that's right...Eleven met Neville Longbottom!

Matthew Lewis who played Neville in the "Harry Potter" franchise posted this picture on Sunday with the caption "A lot of people ask what my tattoo means. Now you know.@milliebobby_brown #XI #Eleven."

While this is taking us a few second to process, will someone please start writing some "Stranger Things"/"Harry Potter" fan fiction, ASAP?
