Honey Lemon secretly takes art classes at SFIT's rival institute, and uncovers the secret side of her artistic idol, Lenore Shimamoto.
Tropes:
- Bait-and-Switch Comment: When Professor Granville catches the heroes plotting to steal SFAI's statue, she tells them not to do it... without her permission, which she's giving.
- Continuity Nod: Honey Lemon still is GoGo's roommate.
- Everybody Knew Already: After Honey Lemon has been keeping the fact she's taking SFAI classes a secret from her friends for fear of their reaction because she thinks the SFAI-SFIT rivalry is Serious Business, they reveal that they'd all already figured it out and they don't actually hate SFAI, it's just a bit of harmless prank war fun.
- Internal Reveal:
- It becomes known to the whole world that Lenore Shimamoto was not only an artist but also a scientist.
- The heroes are made aware of both Obake's existence and that he knows their secret identities.
- Just Whistle: Granville gives Wasabi and Fred whistles and gives them instructions on how many whistles for each situation.
- Mirror Match: Obake pits Fred and Wasabi against robot clones of themselves. They defeat them by switching so they fight each other's clone.
- Noodle Incident: The previous rivalry weeks.
- The Reveal: Shimamoto's journal had Invisible Writing of formulas on the empty pages, and Obake has copies of them now.
- Sdrawkcab Alias: Obake introduces himself as 'Ekabo' while tricking Honey Lemon into giving him Lenore Shimamoto's journal.
- That Was the Last Entry: Lenore Shimamoto's diary ends just as she was about to reveal her scientific discoveries, the day of "the big catastrophe" (supposedly the 1906 San Francisco earthquake that, according to
Word of God, was the point where San Fransokyo was created), leading Honey Lemon to assume that it somehow deterred her. - The Walls Are Closing In: Obake traps GoGo and Honey Lemon in a replica of Shimamoto's secret lab, and the walls are slowly moving and threatening to crush them.
