Lewis wrote online while posing with one of the show’s biggest breakout stars, Eleven. His tattoo matches the Stranger Things star’s name played by Millie Bobby Brown.

As per Refinery 29, it may seem that there’s a connection between Stranger Things and Harry Potter. There are some speculations that maybe Eleven may end up at Hogwarts or maybe Lewis predicted that the show will be a big hit. However, those are just ‘rumors’ for the meaning behind the post.

On another note, the show has been a hit since it premiered on Netflix. Having a show with young stars made it more interesting to a lot of people.

During the 2016 Emmys, the young stars were interviewed about their hit show. “The best part about the ride, meeting everyone that just loves the show because, I mean, they’re all super great to us,” said the young star Gaten Matarazzo.
