Steven has difficulty mastering the dance steps, and Pearl (Deedee Magno Hall) is unsure whether fusion is even possible for him, though Amethyst (Michaela Dietz) and Garnet (Estelle) have more confidence.
As they dance, Steven's gem begins to glow, and he and Connie inadvertently fuse into a single individual—a tall, androgynous, beautiful teenager (voiced by AJ Michalka).
When they stop for a snack at The Big Donut, the employees Lars and Sadie (Matthew Moy and Kate Micucci) are flustered and amazed by their beauty.
Stevonnie, feeling anxious at being the center of attention and the only person dancing, begins to experience a panic attack, visualizing their anxiety as a disco ball closing in around them.
