One Valentine’s day at school, Lisa gets an unsigned card presumably from Frank. Though she is nervous because she has not gotten her period, she has begun to be aware of her sexuality. She notices that Frank’s voice has begun to change, and that a girl named Julie is interested in Frank. However, Lisa still prefers to hang out rather than get involved with anyone romantically. Frank takes Julie to a school dance instead of Lisa, who shows little interest. Frank and Julie become a couple. Cheese asks Lisa if she wants to go out with him to make Frank jealous, which makes Lisa angry. Lisa spends more time with Pooch.

One day, Lisa asks Pooch if he talks to his father, who killed himself. The little man visits Lisa again one night, and subsequently she learns that Ma-ma-oo has had a heart attack. She recovers, but she has to watch her diet and has become weakened. She decides to take daily oolichan grease supplements when her doctor prescribes a fish oil treatment.

Lisa goes with her father and Jimmy to the town of Terrace for a swim meet.
