All we know about Sophie is that she has three possible dads, a flaky husband, and a late mother who was the definition of a free spirit. Now, she's going to be a mother and it's her time to properly shine! Mamma Mia 3 could focus on Sophie as she steps into her new role and look back at her past experiences like the second film did for her mother. Sure, she spent her entire life on that little island, but it could have been just as endearingly zany as her mother's life! (Without the baby daddy mystery.)
