Steven Universe has a very strong continuity. There are many story arcs and references to earlier episodes, and sometimes things that happened ages ago will be brought back into the spotlight. Outside of broken items magically being fixed again, the missing Mr. Universe shirt in "Bismuth", and contradicting summer/fall seasons in seasons 3 and 4, this show has very few continuity errors.
- Cookie Cats are discontinued in episode 1, but they are referenced frequently throughout the rest of the series.
- Steven's cheeseburger backpack. He gets it in episode 3, and it never stops being an item that he carries around with him all the time. In one of the season 2 shorts, Steven gets a Hot Dog Duffel Bag, which then appears in full-length season 3 episode "Same Old World" and several after that.
- Items that Steven owns in general—his jacket, his stuffed animals—are firmly reoccurring.
- Early on in the show, Steven would go to Funland, but in "Serious Steven" he was "banned from all the rides, FOREVER!" The inside of Funland is never seen again...until Mr. Smiley gives him a second chance in season 3 because he was too tired to actually enforce any rules. (Due to having not seen a bed in six days).
- Additionally, Mr. Smiley mentioned enforcing "another" lifetime ban in response to Peridot's behavior towards him, so it's not like he forgot about the first one altogether.
- Greg has the same consistent affectionate nicknames, such as 'stuball,' that he uses for Steven.
- In this world, chips are always known as 'chaaaaps.'
- Peridot's Twitter account only started posting in mid-2016 (after "Too Short to Ride" premiered), but the account itself was created in January 2015 - the same month "Warp Tour" (her first appearance) aired.
- Peedee has received a promotion after the events of the previous episode.
- In "Gem Glow," a Freeze-Frame Bonus showed a glow bracelet in the freezer. It makes a reappearance in this episode—Steven was saving it for Connie all this time.
- The reason Steven is going on this mission is because he did well on the Lunar Sea Spire mission from "Cheeseburger Backpack."
- Purple Puma makes his(?) proper debut after being shown in "Cat Fingers."
- Ronaldo plugs his blog to Steven yet again after "Cat Fingers." If you look closely at his laptop screen, you can see the picture he took of Steven and his shapeshifted fingers from that episode.
- At the end of the episode, Garnet's comment that "we kept Amethyst" is treated like a joke, but actually becomes an important call-forward to the information we learn about her backstory in "On the Run."
So Many Birthdays
- In "Arcade Mania," Onion had so many prize tickets that he was able to buy a moped. In this episode, we see him hacking open the skee-ball machine and stealing tickets from it...explaining how he got so many in the first place.
- Onion's previously-won moped is used to run over a bunch of ketchup packets and then blow up.
Steven the Sword Fighter
- After being first shown with her sword collection in "Together Breakfast," we get a little expansion on Pearl's swordfighting skills.
Lion 2: The Movie
- Dogcopter is introduced after a poster for the movie was previously seen in the background.
- The Hologram-Pearls make a reappearance.
- In "Together Breakfast," Rose's Room had been seen for a split second; Steven was sliding down a pipe, and it abruptly switched from the scary, dark-red setting to a peaceful background of pink clouds (the room's leitmotif was even playing in the background). Now that room has been properly explained.
- The fake Connie tells Steven that "It was incredible!" These were some of the first words Connie spoke to him after they escaped from the giant sea worm monster in "Bubble Buddies."
- Frybo is back at Beach Citywalk Fries, and Steven is terrified of him.
- On the wall of the storeroom in the Big Donut, one of the posters Steven made in "Tiger Millionaire" can be seen.
- After Lars befriended the cool kids in episode 14, he's seen hanging out with them again.
Steven And The Stevens
- Some past locations are seen from previous episodes due to time travel:
- One of the final scenes in "Gem Glow," when Steven throws up from eating too many Cookie Cats (though here, it's because he's bewildered by the sight of a bunch of fighting Stevens).
- A scene from Rose's Room. As the Stevens continue to fight, the Steven from the episode itself parachutes down in the distance.
- The last one is a call-forward to when the ocean went missing in "Ocean Gem."
- The episode is focused around the Mother Centipeedle from "Gem Glow."
An Indirect Kiss
- Like what he learned to do in "Lion 2," Lion let Steven and Connie ride on his back.
- The show keeps time—it's now the beginning of summer.
- Pearl's silly item-summoning ritual from "Lars and the Cool Kids" returns.
- Mayor Dewey is driving his promotional van again, and he refers to Steven as "car wash kid" ala "Cat Fingers."
- This episode continues directly from "Mirror Gem," so of course it has all the continuity of the previous episode attached.
- Greg tries to play a CD in his van just like "Laser Light Cannon."
- During the exposition about corrupted Gems, scenes from previous episodes are shown, including Steven's attempts to befriend and then bubbling Centipeetle.
- Amethyst becomes Purple Puma again.
- As she's fighting the water clones, Pearl exclaims "I hate fighting me!," a reference to the Holo-Pearl from "Steven the Sword Fighter."
- Steven heals Lapis' cracked gem (a concept first introduced in "An Indirect Kiss") with the healing powers he got from the same episode.
- Connie rescues Steven using the portal-roar trick she saw Lion do in "Lion 2."
- Pearl asks Greg about his catchphrase from "Laser Light Cannon," "with the pork chops, and the hot dogs."
- Greg's broken leg from last episode is dealt with, as is his van.
- Greg messes up Steven's new healing powers and causes Steven to lose the ability for a long time.
- In Greg's exposition over the old barn, he mentions that his aunt and uncle (the previous owners of the barn) were big pack rats, and he comments that his family might have a problem. He's referring to his own hoarding problems, as seen with the shed from "Laser Light Cannon."
- All the rooms seen from "Together Breakfast" make a return.
- Garnet calls Kiki/Jenny "pizza daughter," which is probably a reference to her treatment of them from "Beach Party."
- Garnet beats Pearl and Amethyst with the long, shapeshifted arms that she used to save Steven in "Steven and the Stevens."
Keep Beach City Weird
- Ronaldo is obsessing over some of the remnants of previous episodes' adventures:
- The cliffside of the Temple is full of holes from the drill monsters in "Arcade Mania."
- Some rubble from the Red Eye ("Laser Light Cannon") is still stuck in the boardwalk.
- Some leftover blossoms from "Lars and the Cool Kids" are still floating around town.
- Because Steven healed her eyes in "An Indirect Kiss," Connie leaves her glasses off while hanging with him, but keeps them on in front of her parents.
- Rose's plantkinesis is brought up again after being implied and seen in "An Indirect Kiss."
Lion 3: Straight to Video
- The replacement of Cookie Cats, Lion Lickers, are brought up again from their brief mention in "Gem Glow." Steven still thinks they're gross.
- Steven has a dream involving Dogcopter (seen in the last Lion-focused episode).
- Lion's mane also contains Rose's sword, which Steven and Connie used once before, also in "Lion 2: The Movie." There are many items in Lion's mane, all of which either come into play later on or have their origins explained in later episodes.
- Steven goes to The Big Donut to play the videotape because it's the only place he knows that has a VCR. He and Sadie watched a tape on it back in "Joking Victim."
- Steven does not watch the tape at home because he is still grounded from TV after "Fusion Cuisine".
- Steven high-fives Lars' chest, a ritual started in "Lars and the Cool Kids."
- Steven has the water gun from "Ocean Gem."
- More places are seen as Steven leads the Gems around through the warp system:
- The Geode from "House Guest," which is still sealed shut with Greg's duct tape.
- The Sky Spire, where Steven Junior, Steven's goat friend from "Giant Woman," now has kids.
- The Galaxy Warp from "Space Race."
- Again at the Galaxy Warp, Peridot shows up and surveys the area. She finds the exact same "Crying Breakfast Friends" sticker that Steven placed there in "Space Race" and takes it for further study.
- Garnet summons the giant gauntlets from "Garnet's Universe."
- At the end of "Giant Woman," Garnet mentioned that Steven would be able to fuse. Here they are at the beginning of the episode, practicing just that.
- Sadie and Lars are arguing before Stevonnie comes in—their relationship is still beat up after "Island Adventure."
- This episode is a direct reference to "Cheeseburger Backpack." Turns out that the mission to the Lunar Sea Spire was just a test, and Steven is upset that he only got 75% on it.
- The episode itself starts with the Lunar Sea Spire, which Steven forgot at the house, falling out of the closet.
- The Gems' tests are reminiscent of the challenges Steven went through in "Serious Steven." Pearl's room has a music tile puzzle, just like the pyramid did in the second room, and swinging blades that are almost identical to the ones from before. Garnet's in particular has spike plates slamming up and down and a room full of fire and lava.
- Pearl gives us a direct rundown of Steven's powers so far:Pearl: The point is that he's come so far. He can make Rose's bubble! And he's pulled out Rose's shield twice. But he's lost his healing powers. We have to give him another success. He can't lose his confidence like that again.
- MC Bear Bear returns from "Mirror Gem."
- Garnet shows off her heat-resistant powers again when Lars spills hot coffee all over her.
- Cookie Cat's interplanetary backstory comes up again ("I never considered you would be evil!")

On the Run

- Steven rides in Jenny's pizza car again so he and Amethyst can get a lift out of Beach City.
- Pearl and Amethyst bring back some of their moves from "Watermelon Steven," such as the spear energy bursts and the spindash attack.
- Ronaldo's setup in the lighthouse ("Keep Beach City Weird") returns.
- Compared to previous episodes, Steven's powers and the way he handles them are a lot more powerful and mature. This is around the point where he starts coming into his own.
- This episode marks even more passage of time, as it is now winter.
- As Connie mentions, Steven is still grounded from TV.
- As he's trying on clothes, Greg puts on the outfit that he wore during Fusion Cuisine. Steven points out that the Maheswarans will think he only has one fancy shirt, which is true.
- The waffle iron Greg kept in his van from "Laser Light Cannon" is put into use cooking eggs in the middle of a snowstorm.
- The shooting star from "Monster Buddies" returns. Not only that, but the Gems were trying to use it to blow up the galaxy warp, playing off of the events at the end of "Warp Tour."
- In the end, the episode turns out to be dedicated to Garnet's future vision, just like the episode of the same name. Continuing off of that one, Garnet is still trying to help Steven understand what she sees every day.
- The storage shed from "Laser Light Cannon" returns, along with all the items previously seen in it. Greg discovers the picture frame that Steven broke the first time he had ventured inside.
- Amethyst turns into Purple Puma again.
- Steven is thrilled when he finds a box of new books to read.
- Following his promotion from "Frybo," Peedee is working the counter.
- Greg's previously established fear of shapeshifting is explained in this episode - Amethyst used it to upset him in the past, and does so again in this episode.

- The Kindergarten returns, and Amethyst still looks uncomfortable to be there.
- Steven says "funky flow," just like "Bubble Buddies."
- Peridot is back with Steven's Crying Breakfast Friends sticker.
- Peridot also references the Red Eye from "Laser Light Cannon," which was apparently a scouting device to look for Gems on the planet.
- Some items from inside Lion's mane—specifically, Rose's sword and the flag with her emblem on it—return.
- The armory from "Lion 2: Straight to Video" is back, and Steven tells Pearl that he's been here before. He also calls up the weapons and armor by poking himself in random places, the way Connie did the first time they visited. Some of the weapons he brings up are the light cannons from episode 2.
- Steven's bike and helmet from "Bubble Buddies" appear again. Steven had them stored in Lion's pocket dimension.
- When Steven is retrieving the flag to cheer Pearl up, he takes a deep breath first—as seen in "Lion 3," there's no air in Lion's mane.
- This episode is a continuation of the Steven-reads-Unfamiliar-Familiar subplot from "Marble Madness."
- Rose's room returns, and so does the tiny pink floating whale. He gives her a high-five again.
- Steven is also still visibly nervous at being in the room, warning Connie that they should "keep it simple" and not overload the room with requests.
- Steven is wielding the T-shirt cannon from inside Greg's storage shed (seen in "Laser Light Cannon").

- The arrival of Bismuth was hinted all the way back in season 1 episode "Lion 3: Straight to Video", when Steven first entered Lion's mane, and we could see Bismuth's gem in a bubble. Fans speculated for two years about what or whom that mysterious bubbled object was.

- Peridot has gained some more control over her metal power since their debut in "Too Short to Ride", though she's still not very good at it.

- This episode picks up where Beta left off.
- Amethyst is still determined to beat Jasper in a fight.
- Jasper's army includes gem mutants and even the Water Bear monster from "Love Letters" (or one that looks identical to it, since corrupted gems of the same type look the same). Note also how in "Love Letters", the monster was never poofed or bubbled.
- Peridot still attempts to use her metal powers, and still struggles with it.
- This is the episode where Pink Diamond is finally mentioned for the first time. In many other episodes, we've seen some Diamond Authority symbols include the pink diamond, and some that exclude it, implying something happened to Pink Diamond. This episode also confirms that Rose did something to Pink Diamond.

- Following the ejection of the Rubies into space, the gems now own the Roaming Eye.
- The gems are still poofing and bubbling the remainder of Jasper's army in the Beta Kindergarten.
- Continues the notion that corruption is not present on Homeworld, and Peridot (being new to Earth) has no idea about the nature of corrupted gems.
- The Crewniverse actually appear to have ret-conned Peridot's resistance to poofing.
- It should be noted that before Garnet poofed her back in "catch and release" Peridot had been hit by a strong electric shock from her(Garnet)and then slammed into the ground very hard, and that an electric shock (also courtesy of Garnet) was strong enough to poof a gem mutant in "when it rains".
- It should also be noted that we have yet to receive an exact value on how strong Garnet is. There's nothing to suggest that she definitely isn't strong enough to poof a Peridot, so this isn't necessarily a retcon.
- Interestingly, the gems appear to have all dropped their Bismuth upgrades, Amethyst included. Possibly because of what Bismuth did to Steven, although it's never explained.
Know Your Fusion
- The episode has so many callbacks that it's called out In-Universe by Sardonyx.
- When Steven and Amethyst ask Pearl and Garnet if they know who defeated Jasper, Garnet replies "Peridot". Technically, she's right, as Peridot was the one who poofed Jasper at the end of the fight in "Earthlings".
- Garnet gets so excited she starts screaming and shaking Pearl, her facial expression similar to her reaction when Steven first fused with Connie during "Alone Together".
- A clip from the season 1 episode "Giant Woman" showing off Opal's skills is played for the audience, and Sardonyx wonders if Smoky Quartz has her aiming ability.
- All the other fusions Amethyst has been a part of are also given call backs, including Sugilite and Alexandrite.
- Smoky is tested for the strength of Sugilite shown off during "Coach Steven". When they fail, Sardonyx says that maybe they're just strong In the Real Way, singing it like Pearl's song from that episode.
- Sugilite's voice clips from the episode are used, and Sardonyx wonders if they have to pay her voice actress for it.
- Smoky is also tested for having a Breath Weapon like Alexandrite does, first seen in the season 3 episode "Super Watermelon Island".
- Sardonyx's mug has "I love EC" written on it, a reference to Empire City in a similar vein to "I Love NY".
- Smoky Quartz shows insecurities similar to the ones explored in Steven and Amethyst during "Steven Vs Amethyst", frequently putting themself down and calling themself useless.
- This isn't the first time we've seen a room in the temple grow unstable and dangerous to those inside it. Unlike "Rose's Room" its not due to the room being overloaded, but instead it's due to the gem it belongs to no longer existing.
- The librarian can be seen reading a copy of Passions of Xanxor, which has appeared twice in the show so far ("Maximum Capacity" and in "Greg the Babysitter").
- Buddy is imagined to look like Jamie by Steven and Connie in their flashbacks, referencing the episode "Historical Friction" where we first learned about how Beach City was founded via a play, in which Jamie played the role of Buddy.
- Buddy also recognizes Pearl and Garnet when he encounters them, remembering how they saved the ship and allowed William Dewey to claim land near Beach City.
- In Steven and Connie's re-imagining of the "old" version of the gems, they're wearing the outfits they wore in the painting seen in "Too Many Birthdays"
- The sketches in the journal show many places Steven and the gems have gone during the series, including the Strawberry Battlefield, The Sea Spire, the Temple, the communication hub, the Prime Kindergarten, and more.
- The sketches also show something Steven is not familiar with, resembling a cage-like legged structure.
- Buddy himself visits many of the places during the episode, notably the Strawberry Battlefield and the Prime Kindergarten, with his encounter with Rose happening as he looks for the Sand Castle in the desert.
- While in the Kindergarten, Amethyst once again references the long period of time she spent there by herself, and talks to the rocks there like old friends.
- Continuity ERROR - Amethyst appears as she does currently, however in Story for Steven, amethyst has a much younger form with short hair and this is much later than Buddy's Book.
- Rose is seen with seven lions in the desert near where Steven first met Lion, possibly hinting at Lion's origins. They're all just as tame as Lion is to Steven.
- Buddy attempts to stick his head inside the mouth of one of the lions, much like Steven did when he first met Lion in "Steven's Lion". Though Steven did it for a joke, but Buddy did it to commit suicide, kid's show style.
- This episode actually has a continuity ERROR in the season changes - it's somehow still September like it was in "Same Old World", despite the 25 episodes between them.
- This episode confirms that unstable fusions can hallucinate - as visualised when Stevonnie became unstable in "Alone Together" and "Beach City Drift".
- Steven's hallucination sequence features several callbacks to recent events - poofing Bismuth, releasing Eyeball into space, watching Jasper corrupt, and his mother shattering Pink Diamond.
- Steven uses his floating abilities.
- The ground Steven and Connie land on after falling off the Sky Arena looks like the ground Ruby and Sapphire landed on after they jumped off the arena in "The Answer".

- Andy appears again from "Gem Harvest".
- This episode continues the Rose-shattered-Pink Diamond plot thread.
- Buddy's journal appears again.
- Greg mentions how he used to be good at fence-jumping, as he did in "Story for Steven".
- The fence also has a "Keep Out" sign, with "Please" in Rose's handwriting below it, as did the fence in "Story for Steven".
- The size of the diamonds appears to have been retconned - unless some deceptive perception was in play, "The Answer" and "Message Recieved" make the pearls hight somewhere around the diamonds knees, but now the diamonds are big enough to wrap one hand around the pearls if they really wanted to.note
