The upcoming season 6 of Young Sheldon suggests that fans should be worried about Missy, the only daughter of George and Mary Cooper. A promotional still from the set features Missy with a bleak look on her face, hinting that something bad is going down involving her. While the show has diversified its narrative by tackling arcs that aren't always focused on Sheldon, it continues to underutilize Missy's popularity. Dubbed as the best Cooper family member, Missy has incredible maturity for her age and could carry more of her own storylines. However, any troubling Missy storyline is already set up to have an overall happy ending, as her The Big Bang Theory appearance revealed that she will grow up and find happiness in her own family.
