You should keep a close eye on your cactus.
"Prickly Pair" is the 10th episode of Steven Universe Future and the 10th episode overall.
The episode begins at the conservatory where Steven shows the Gems that he has taken up gardening since leaving Little Homeschool. He proudly states that he grew them without using his powers, and names each plant after the people who have left his life. Steven pricks his finger while transplanting a cactus cutting, then heals it with his saliva and touches the cutting to finish the process.
Steven finds the next day that the cutting has grown and become sentient and introduces it to the Gems, with Amethyst naming it "Cactus Steven". Steven spends the day with the cactus while bemoaning how everyone left him and that his own life has had no direction since leaving Little Homeschool, as there is no one left to help.
The next day Steven finds that Cactus Steven is able to talk, repeating back what he has said. Cactus Steven repeats back Steven's laments to the Gems, which causes Steven to panic and hide it away from them. Amethyst checks on Steven, at which he nervously denies that anything is wrong.
The next day Steven finds that Cactus Steven has grown deformed and continues to repeat everything he says, angering him and causing him to turn pink. Steven leaves the greenhouse when Pearl calls him for dinner.
Steven awakens that evening to the sound of breaking glass and finds that Cactus Steven has broken out. Cactus Steven ambushes him in the house, now being able to move on its own having grown limbs. Steven attempts to fend it off when the Crystal Gems arrive. The Gems initially manage to gain the upper hand and knock Cactus Steven against the sink, spraying water and allowing it to grow even larger with multiple limbs and heads. The Gems are outmatched and Cactus Steven continues to repeat every negative opinion Steven told it about them. Upon realizing it is just continuing to mimic him, Steven ends the fighting by apologizing and hugging it. This causes Cactus Steven to sprout flowers and gives one to Steven before busting through the house door and leaving. The gems ask Steven if they need to talk about his issues, which Steven denies stating that he has said enough.
