In the season premiere episode, "Unbraceable You," Frankie makes a giant blunder when she discovers that school started a week earlier than she thought, and Sue and Brick must scramble to catch up on the days they've missed and re-acclimate themselves to school life. Meanwhile, it looks like the "Year of Sue" might be starting off on a high when she finally gets her braces removed. Axl beats Mike at basketball for the first time in his life, and Brick gets creative in an attempt to find the perfect school book bag.

In an attempt to become more social, Brick shocks Frankie and Mike by informing them that he'd like to go to his middle school's Fall Fantasy Dance, Axl begins to panic when he discovers that he needs to declare a college major by the end of the week -- and he has absolutely no idea what he wants to do, and Sue finds herself becoming a bit twitchy and nervous when she begins to drink a lot of coffee in an attempt to appear more mature and sophisticated, now that she's a high school senior.
