The final two episodes of "Young Sheldon" proved to be both devastating for audiences and momentous for the characters involved. Not only did viewers find out how Sheldon Cooper ends up getting to CalTech and watched the sitcom echo its pilot episode in two big ways, they also got to drop in on an adult Amy Farrah Fowler and Sheldon as Sheldon writes his memoirs. Through both background context clues and dialogue excerpts, one can see how their lives have changed since "The Big Bang Theory" concluded in 2019.
