In Stranger Things season 3, we got to know Mike and Nancy's mom, Karen Wheeler a little bit better. In the previous seasons, we learned that Mrs. Wheeler really does care for her children, even if she has no idea they've been fighting monsters from an alternate dimension. Remember when the kids thought Will died and Mrs. Wheeler invited Mike to go rent a movie, even an R-rated one? She also tells her daughter Nancy that she's open to chat about anything, following her discovery of Nancy's fling with Steve.

But even though she really loves her family, by season 3, it's clear Nancy is frustrated with her marriage and family life, almost starting an affair with Billy, although she ultimately chooses her family. It's clear Karen has a lot going on emotionally. While watching the show, it almost feels like you personally know Mrs. Wheeler, thanks to the actress that plays her, Cara Buono. This isn't Cara's first big show. Here are some fun facts about Cara Buono.
