Thanks to "Young Sheldon," we get to see in detail what Missy Cooper's upbringing is like, whereas "The Big Bang Theory" only provides brief, vague references to her childhood. She's certainly not as intelligent as Sheldon, but she does well enough in school. On top of that, she doesn't take any flak from anyone and is more than capable of standing her ground when need be. Sure, she gets into some mischief now and again, but overall, she seems to have all the tools necessary to live out a fulfilling adulthood.
To reach this adulthood, though, Missy has to get through some rough spots. First and foremost is the unexpected death of her father, George Sr. (Lance Barber), which is undoubtedly difficult on the entire family. Then, according to Sheldon on "The Big Bang Theory," she struggles to graduate high school, taking a couple of years longer than most to do so. To top all of that off, she ultimately becomes a divorced mother of multiple children who has to resort to menial labor just to keep food on the table and a roof over their heads.
With all of this in mind, it's even more satisfying to know that Missy Cooper goes on to live a happy life after "The Big Bang Theory."
