Plot summary
While Steven (Zach Callison), Garnet (Estelle), Amethyst (Michaela Dietz) and Pearl (Deedee Magno Hall) are watching the fictional Japanese movie Lonely Blade, Pearl critiques the film's sword fighting techniques and offers to give Steven a proper demonstration. At her arena, Pearl summons "Holo-Pearl", a holographic version of herself to spar with. After Pearl wins a sparring match with Holo-Pearl, she begins to show Steven the basics of sword-fighting. However, Pearl's lessons bore Steven, making him clamor for Pearl to teach him the signature move from the Lonely Blade movie, much to Pearl's chagrin. While Pearl is distracted talking to Steven, Holo-Pearl impales Pearl with her sword, which causes Pearl to lose her physical form, leaving nothing but her gemstone. Although Steven is distraught, Garnet and Amethyst assure him that Pearl has simply retreated into her gem and will return, projecting a new body, once she has healed.
Two weeks pass, and Pearl is still healing inside her gem. Steven decides to use Holo-Pearl as a replacement for the real Pearl. However, Holo-Pearl only knows how to sword fight, seeing everything as a potential opponent. Garnet and Amethyst urge Steven to stop using it and wait for the real Pearl to come back. After Holo-Pearl cuts down the real Pearl's favorite tree, Steven becomes infuriated and tries to drive Holo-Pearl away.
Later that night, Holo-Pearl continues to ask Steven to be challenged in combat, though he repeatedly refuses. But when she destroys the television, Steven becomes fed up and fights back against Holo-Pearl, accidentally activating her "advanced" mode. After an intense fight, Steven is able to destroy Holo-Pearl permanently. Garnet and Amethyst hear the commotion and come to check on Steven; and while he is explaining what he has learned, Pearl finally regenerates with a new outfit and faces the mess left from what recently happened, while Steven happily parades around celebrating her return.
