In the episode, Tina gets her chance to be soloist of the Hormone-iums in a play, but realizes the role could end up ruining her social status.
The Hormone-iums are given a special show to perform on Friday, all about mono, and during the rehearsal Tina finds herself disagreeing with Mr. Frond's alarmist lyrics.
Though Tina loves kissing and initially wants to quit The Hormone-iums, Mr. Frond bribes her with a permanent lead singer role.
Louise convinces her to pitch the wine shoe idea to Mr. Fischoeder and his brother, Felix, who pass on the Cinderella-inspired presentation.
The fact that Tina can be exactly that is now the most normal thing in the world is the greatest achievement on display tonight, even if it was first accomplished long before this.
