Season 2

"Season 2" is the second season of the television program, Steven Universe. The season premiered on March 13, 2015, beginning with the episode "Full Disclosure". New characters will be introduced over the course of the season. Because of "StevenBomb", a week full of new episodes including the season 1 finale and the premiere of season 2, four episodes were moved from season 1 and were subsequently aired during season 2. Those episodes are "Open Book", "Say Uncle", "Story for Steven", and "Shirt Club", respectively.

Season 2 went on a summer hiatus after "Reformed" on April 30, and returned with a second StevenBomb, beginning with "Sworn to the Sword", running from June 15 to June 19. The third StevenBomb (called "Week of Sardonyx") aired starting with the first episode called "Cry for Help" on July 13 and ending with "Friend Ship" on July 17, marking the end of a short hiatus and the beginning of another one. New weekly episodes were planned to return in August, but got pushed back to September 10th due to unspecified "boring production reasons." After 6 weeks of new episodes, the show went on winter hiatus on October 15, 2015, and is expected to return in 2016 after the winter break.

Summary
Season 2 starts off with the following events of the first Homeworld Invasion, with "Full Disclosure", where Steven realizes the impact his life and safety has on his friends and family, taking therefore the decision to cut out Connie and all the other humans from his life, a plan that isn't well succeeded when Connie confronts him and the two decide to be together no matter what. This isn't the end of his post-traumatic stress however, as in "Joy Ride", Steven comes clean about his insecurities to The Cool Kids and the four go for a car ride in the middle of the night, coming across Peridot's pod in a wheat field, that is apprehended by the Crystal Gems. In "Love Letters", Steven reconnects with Jamie, the mail man, who, when meeting Garnet, falls madly in love with her, however, after some incidents with love letters, Garnet has a talk with him about how love takes work. In "Reformed", the Crystal Gems find The Slinker in Amethyst's room, and the many encounters with the gem monster cause Amethyst to poof and generate, trying to impress Garnet each time but failing. In the end she assumes a stable form.

Steven and Connie's relationship keeps getting better in "Sworn to the Sword", where Steven asks Pearl to teach the wonders of sword fighting, but Pearl gets overzealous and teaches Connie how to sword fight in Steven's advantage, over everything, just like she once did with Rose Quartz. Steven and Connie however get in a sword fight with Pearl and make her understand that they wish to fight together. Meanwhile, Ronaldo Fryman has been working on a documentary about the Gems, ever since the first Homeworld invasion, which the Gems watch on the wide web, in "Rising Tides, Crashing Skies". But the plot thickens when, in a successful attempt to find Peridot in the Kindergarten, Steven and Garnet come across the monstrous creatures created by Homeworld, forced fusions of fallen Crystal Gems, which off puts Garnet greatly. Peridot is able to escape however. In "We Need to Talk", Connie and Steven accidentally fuse into Stevonnie in front of Greg, who, surprised, decides to tell the kids the story of how he met Rainbow Quartz, Pearl and Rose Quartz's fusion, and of how he, not successfully, tried to fuse with Steven's mother. However the Gems haven't stopped looking for Malachite, as they do so in "Chille Tid", where in a sleepover, Steven is able to communicate with Lapis and Jasper through his dreams.

In "Cry for Help", the escapee Peridot strikes again, by fixing the Communication Hub in order to contact Yellow Diamond, back in Homeworld, which she successfully does until Pearl and Garnet form Sardonyx to dismantle the hub. Pearl, however, gets overzealous of revisiting the feeling of being Sardonyx with Garnet, building the hub back two times only to fuse with Garnet more times. Garnet comes to know of this and is not happy, and decides to let a little steam off by going on a road trip with Greg and Steven in "Keystone Motel", where the disagreements between Ruby and Sapphire cause her to unfuse. They fuse again when the two realize how silly with each other they're being. In "Onion Friend", Steven and Amethyst find themselves visiting Onion's house, where Amethyst reunites with her old friend Vidalia, Onion's mother. Onion and Steven go off on weird shenanigans around his mysterious house. In "Historical Friction", Steven requests Pearl's help on upgrading the play him and Jamie are putting together about the creation of Beach City. Meanwhile in "Friend Ship", Pearl has been brainstorming new ways to catch Peridot, in order to make up for her Sardonyx fiasco, finding a way to know Peridot's location through her pod. They meet Peridot in an old ship, where Peridot has plans to trap them and kill them off, unsuccessfully, as the gems are able to escape, if not in a better state, since Pearl and Garnet are able to talk off their feelings and their conflict comes to an end. They almost catch Peridot at the ship, but she's able to escape yet again, without a foot.

In "Nightmare Hospital", Connie carries on her sword fighting lessons with Pearl, only that her mother finds out about her secret and confiscates Rose's Sword. Which leads to Connie and Steven traveling to the hospital where Connie's mother works to retrieve the sword, only to meet the gem fusions found previously in the Kindergarten, defeating them in a sword fight. A few days later in "Sadie's Song", Steven discovers Sadie's secret talent of singing, and with her mother, the two work together to make Sadie's performance as gaudy as possible, overdoing it, causing some stress on Sadie, which, luckily, ends well.

One night, in "Catch and Release", Peridot kidnaps Steven and orders him to fix the broken Homeworld Warp, but she is caught by the Crystal Gems and is poofed and bubbled. She is later released by Steven and spills some information on the Cluster, but before revealing further information she locks herself in the Steven's Bathroom, where she stays until "When it Rains". In this episode, she mistakes a thunderstorm as being the Cluster emerging, but Steven explains rain to her, leading her to believe that Steven is very intelligent. Peridot shows Steven the gem experiment logs in the Prime Kindergarten Control Room as well as more information on the Cluster. As they're leaving the Kindergarten they are ambushed by Cluster Gems, but are saved by the Crystal Gems. Peridot then decides that she should tell them all more about the Cluster, which she does in "Back to the Barn", where the gems get going on the construction of a drill that leads to a robot engineering fight between Pearl and Peridot, but the two settle things up. However, Pearl isn't the only one Peridot upsets, since, in "Too Far", when going to the Kindergarten to get one of the injector drills, Peridot hurts Amethyst's feelings by telling her she's defective for being to small for the Quartz she is. However, the two also settle things up when Peridot saves Amethyst from a runaway drill, and apologizes.
