Netflix's Stranger Things became an instant hit and pop culture phenomenon making stars out of its young cast as well as revitalizing Winona Rider's career as Joyce, the mother figure of the group. Fan theories ran amock after the first season and now that we're finally in Season 4, with the second part coming in July, it's fun to look back at theories and see how wrong or right they were.

In this case, very right.

Warning: Spoilers for Stranger Things Season 4 ahead, obviously.
