In an attempt to get the students in his class to stop texting and communicate in person, Cory gives them a homework assignment that teaches them how to communicate face to face, ultimately sparking a real connection between Riley and Lucas.

Riley becomes jealous when another girl flirts with Lucas, so she enlists Maya and Farkle's help to learn how to flirt too.

Cory struggles with Riley growing up when he learns she'd rather go to the school dance then participate in their yearly tradition of riding the Coney Island roller coaster. Simultaneously, he is dealing with the outcome of giving Maya an "F."

After Cory teaches a lesson on truth, Riley and Maya struggle with whether or not it was right to lie to Farkle and tell him he’s a good actor and if Maya should keep the locket she found, even though it doesn't belong to her.

The kids face a trilogy of terror when Riley has a sleepover at Maya's with her Gammy Hart and pet ferret. Auggie confronts the monster under his bed, and Farkle tackles his most terrifying fear yet - playing softball.

Riley is asked to the semi-formal dance by a classmate named Charlie and is torn whether to go with him or Lucas. Meanwhile, Cory’s brother Eric is paid a visit from an old friend.

Riley, Maya, Farkle and Lucas start their freshmen year and quickly learn their place as smaller fish in a much bigger lake.
