Amethyst van der Troll returns from summer break with a surprise—her gem has finally gotten its glow, and now she can cast spells like the rest of her friends! Amethyst proves to be a natural spellcaster, saving a troll from one of Ruby's misfired spells. When Ruby gets jealous of Amethyst's talent (and mistakenly thinks she's moving in on her boyfriend Rock), she kicks her out of the BFFL.
Ruby later grows to regret her decision, but she's too proud to apologize directly, and Amethyst worries that she's changed too much to remain friends, as beforehand all she did was what everyone else wanted. Onyx, Topaz, and Sapphire decide to scare them back together, magically turning Topaz into a troll-eating ogre. Ruby fights bravely for Amethyst's sake, and once the ruse is discovered, she welcomes her back into the gang with open arms—though reminding her to watch the hair.
Afterwards, Topaz is restored to normal and the BFFL see Amethyst off at her house. She updates her laptop with a new picture of herself and her friends, telling Wa-Wa about her day, and feels things are just beginning for her and her friends.
