Amethyst has started a new program wherein Gems choose jobs in Beach City. While happy with the effort, Steven is unhappy that they have chosen jobs that resemble what they did on Homeworld. He attempts to mix it up by having the Gems pick different occupations, but this results in panic and destruction as the Gems work at jobs they are unsuited for.
The Rose Quartzes that Pink Diamond created to resemble her Rose Quartz self travel to Beach City to visit Steven. While the Crystal Gems are uncomfortable with their presence, Steven doesn't have the heart to ask them to leave.
Rainbow Quartz 2.0 promised to hang out with Onion the same day Sunstone scheduled a home safety Geminar! How can Steven be in two places, and two fusions, at once?
All the trauma Steven has accumulated since his childhood are released in a powerful but dangerous new physical form. Steven's friends must find a way to stop him before he destroys the town.
