In the season premiere episode, "Not Your Brother's Drop Off," Sue cannot contain her excitement over getting ready to move out of the house and into the dorm to start college. But Sue's excitement starts to give way to dread when she accidentally burns her hair and ends up having to cut it short, Axl doesn't want to join the family and help his sister move into the dorm, Frankie finds herself not feeling sad about Sue moving out of the house, and Mike overwhelms his daughter with learning financial and safety guidelines to keep her safe at school. Meanwhile, Brick doesn't know what to do when his girlfriend, Cindy, tells him that she wants to take their relationship to the next level.

Frankie is speechless when Mike -- whose entire wardrobe consists of long sleeved flannel shirts -- decides to wear a short sleeved Hawaiian shirt when they go out to dinner with some friends. Meanwhile, while Sue excitedly finds herself signing up for as many no-cut college clubs as she can, she accidentally tells Devin how much Axl loves her, which scares Devin and leads her to question their relationship; and Brick gets a little too ambitious while tackling his chore of cleaning the bathroom.
