Steven announces to Peridot that he’s going to use his projection powers to help the other Gems in any way he can.

A common thread in the elder Gems’ treatment of Steven is a benign condescension towards him, to which he usually responds with frustration. Considering Malachite’s level of danger a more immediate threat than the Cluster, Garnet (Estelle), Pearl (Deedee Magno), and Amethyst (Michaela Dietz) agree to deal with Malachite first, telling Steven and the flustered Peridot (Shelby Rabara) to stay behind. When Steven wakes up, he warns the Crystal Gems that Malachite has returned. (We’ll leave the horrifying question of whether or not Steven was merely steering the body of an unconscious watermelon person for another essay.) Steven, who has apparently been refining his skill to surf into the consciousness of other beings, enters the body of a watermelon person, and eventually runs across Malachite, who devours the hapless tele-Steven. The result is that the two Gems’ unstable fusion is allowing Malachite to rampage around the periphery of Mask Island, the adopted home of Steven’s cucurbit culture. What’s more, Lapis Lazuli’s (Jennifer Paz) ability to control her worse half, Jasper (Kimberly Brooks), is finally breaking down. Surprise! Malachite (Kimberly Brooks and Jennifer Paz) is back. Steven Universe: The Shadow over Innsmouth for all ages. A species with their own religion and culture and, apparently, a willingness to perform ritualistic sacrifices of their own to satiate a monstrous chimera off the shore of their island. We’ve now gotten explicit proof that Steven’s inadvertently capable of creating entire species of self-aware beings out of whole cloth. Season one’s “Watermelon Steven” at least gave us some plausible flexibility about the sapience of Steven’s (Zach Callison) watermelon people, but the writers of “Super Watermelon Island” have really done away with any ambiguity. The opening to this episode disturbed me once I thought about it.
