Steven Universe is normally a continuity-heavy series where things that change in one episode are regularly called back to in another, and some episodes' plots are directly derived from earlier ones.
- "Steven's Lion", "Lion 2: The Movie", and "Lion 3: Straight to Video" don't actually have much to do with each other as far as their individual plots are concerned, aside from Lion having a major role in each. "Lion 2" and "Lion 3" receive an actual follow-up in "Rose's Scabbard", which revisits certain elements of the previous episodes (in particular, Rose's armory and her Cool Sword). "Lion 4: Alternate Ending" follows up on "Lion 3" in a different way, as Steven reassesses the message from his mother to find some hidden purpose.
- "House Guest", the first episode of the first season's second half, deals with one of the immediate consequences of "Mirror Gem"/"Ocean Gem", the half-season finale (Greg's broken leg, an injury he suffered in "Ocean Gem").
- "Open Book" is one to "Rose's Room". Both are set in the eponymous room, and both have a similar plot where Steven has to deal with the room's strange effects.
- "The Test" kicks off when Steven discovers that the Sea Spire mission from "Cheeseburger Backpack" was a test, which he thinks he failed.
- The first episode of season 2, "Full Disclosure", picks up directly from the ending of the season 1 finale, "The Return"/"Jail Break", as Steven tries to cope in the aftermath of the latter.
- "We Need to Talk" is a direct follow-up to "Story for Steven", both Whole-Episode Flashbacks centered on Greg and Rose. "Greg the Babysitter" is a third set later still, though the focus is a bit more on Greg specifically.
- "Coach Steven" centers on Garnet and Amethyst fusing, inspiring anxiety (and a song) from Pearl until their fusion goes out of control and Pearl has to stop her. "Cry for Help" starts with Garnet deciding to fuse with Pearl instead of Amethyst for a similar task, causing Amethyst to experience similar feelings (and also a song), but their fusion goes wrong in a different way.
- "Super Watermelon Island" is not only a sequel to "Watermelon Steven", it is also part of the resolution of two separate Story Arcs (Malachite and the Cluster/Peridot's redemption). "Escapism" returns to the Watermelon Stevens' island, but it's more of a backdrop as Steven is there for incidental reasons.
- The plot of "Beach City Drift" is kicked off when Kevin, the guy who harassed Steven and Connie in "Alone Together", reappears, causing them to try to get back at him. In "Kevin Party", he comes back again and invites them to a party, which they use as an opportunity to reconnect when they'd spent the last few episodes not speaking to each other.
- "Monster Buddies" ends with Steven hoping he'll find some way to help a Gem monster he befriended. "Monster Reunion" begins with Steven discovering that his healing powers still work, and he partially succeeds in using them for just such a task.
- In "Historical Friction", the characters put on a play about the founding of Beach City. "Buddy's Book" picks up where the play's story left off. However, it stars the play's Deuteragonist, which makes it more of a Spin-Off Sequel Episode.
- "Tiger Millionaire" is a Pro Wrestling Episode where Steven discovers Amethyst wrestles as Percussive Therapy, and joins her to have fun together. Several seasons later, "Tiger Philanthropist" shows they were still wrestling, but Amethyst quits suddenly because she feels better about herself, leaving Steven uncertain whether to keep at it or how.
- In "The New Lars", Steven possesses Lars' body. Everyone likes Lars more for this, and only Sadie gets suspicious, which makes Lars realize no one else really knows him. In "The Good Lars", Lars tries to use baking for a potluck as an opportunity to open up to other people.
- "Sadie Killer" ends with Sadie joining Steven, Buck, Jenny, and Sour Cream's band after quitting her job. "The Big Show" is Steven's in-universe documentary of the band several months later as Greg gets them a gig in Empire City.
