Warning: Contains SPOILERS for Inside Out 2!Inside Out 2 reveals that Riley has a deep dark secret, and while it is a neat story beat in the sequel, it makes one popular Inside Out theory far less likely. In the lead-up to Inside Out 2, it was clear that several years of Riley’s life had passed, leading to many different theories regarding what had happened to Riley in the years that had elapsed between the two Inside Out movies. One theory stood out above all the rest as being the most popular, and while Inside Out 2 didn’t explicitly de-confirm it, it’s now far less likely.
