- "Fear. It's the most basic, the most human emotion. As kids, we're afraid of everything. The dark... The boogeyman under the bed... And we pray for morning. For the monsters to go away. Though they never do. Not really. Just ask Jason Blossom."
- —Jughead Jones

With Riverdale High's annual variety show approaching, Valerie's efforts to help Archie prepare for his big debut performance at the event leads to some major fallout between her and Josie over Valerie's spare time with Archie. Meanwhile, Betty and Jughead's personal investigation into Jason's murder brings them to a home for troubled youth and they come face-to-face with Betty's sister Polly, who is revealed to be seven months pregnant. Polly is happy to see Betty, but she does not react well to the news of Jason's death. As Veronica decides to rebuild her relationship with her mother, she learns that Hermione is using her for her own advantages. At the same time, Hermione's first day at working at Andrew's Construction brings her and Archie's father, Fred, closer. Veronica decides to join Josie's band as the new backup singer after Valerie quits. Josie deals with her own family pressure after her overbearing and difficult father visits for her performance at the variety show. After Archie realizes that Valerie did not know about Josie's father being in town, he encourages her to reconcile with Josie. Betty finally confronts her parents about Jason Blossom's death where they continue to deny any involvement in the murder. Later, Betty and Jughead grow closer when they find a car hidden in the woods containing drugs and Jason's belongings, but when they bring the police to the scene, an unseen person who has been following Betty and Jughead torches the car and destroys any incriminating evidence.
