Be honest, have you kinda totally forgotten what happened last on Stranger Things?

I don't know about you, but I'm going to have to do a Stranger Things rewatch before the loooooooong-awaited Season 4 drops on May 27 because it's been almost THREE (!!) years since we were last with the Hawkins gang and I have forgotten just so much. To be fair, some, uh, things have happened in the world since 2019 and it pushed things out of my brain that I like, including Stranger Things. (This happened to me with Ozark, too.) I definitely remember a mall and a Mind Flayer, but everything else is a little foggy. Help! Am I the only one that needs a refresher? Either way, I'm excited to get reacquainted with the kids (well, grown kids now!) in a few weeks.
