The last episode of Steven Universe – “It Could’ve Been Great” – ended on a bit of a cliffhanger: after realizing that Peridot (Shelby Rabara) may not be as on-board with the Crystal Gems as he thought she was, Steven (Zach Callison) watches her sneak off with a special communication device stolen from the Homeworld base on the moon. We were left wondering what this meant for her standing among Garnet (Estelle), Pearl (Deedee Magno), and Amethyst (Michaela Dietz), as well as what it meant for the Gems’ plan to destroy the dangerous weapon incubating within the planet. “Message Received” doesn’t hesitate to answer these questions.
