37. Alone Together

As the episode begins, the Crystal Gems are trying to teach Steven (Zach Callison) to dance, hoping he will develop the power of fusion—the ability of Gems to merge their minds and bodies to form more powerful individuals. 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.

Later, Steven discusses his difficulties with Connie (Grace Rolek). She tells him she admires him for even trying, saying she's usually too nervous to dance in front of other people. Steven invites her to dance with him on the beach. 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).

They show the Gems their fused form—dubbed “Stevonnie” by Amethyst. Pearl is perturbed by the unprecedented fusion of a Gem with a human, but Garnet is thrilled, and advises Stevonnie to “go have fun!”

Stevonnie revels in the capabilities of their fused body, running and diving on the beach. 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. Steven and Connie, through Stevonnie's voice, briefly check in with each other to ensure that they are comfortable remaining fused. Steven's friend Sour Cream (Brian Posehn) meets Stevonnie, and invites them to a rave he's DJing later that night.

At the rave, Stevonnie's graceful and athletic moves on the dance floor draw everyone's attention and admiration. 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. They are interrupted by Kevin (Andrew Kishino), an arrogant teenager who wants them to dance with them. Stevonnie flees the dance floor, feeling isolated.

Kevin follows them, invading Stevonnie's personal space and refusing to take no for an answer. Eventually, disgusted, they agree to dance with him. Stevonnie's violent and angry dance moves confuse and disconcert Kevin, and soon Stevonnie falls apart and unfuses. Kevin panics and leaves. Steven and Connie laugh with nervous relief, and Sour Cream showers them with glowsticks as they run about on the dance floor.
