a giant drill lands on the hillside, and Spinel, a deranged and cartoonish Gem, appears, announcing her intent to kill Steven and the rest of the Earth ("Other Friends"). Using a scythe-like weapon, she "poofs" Pearl, Garnet, and Amethyst back into their gem forms; her attacks also weaken Steven's Gem powers, though his body is unharmed. Steven manages to poof Spinel with the scythe.

Steven calls his father, Greg, for help. The Gems regenerate their bodies (including Ruby and Sapphire separately), but their memories somehow have been erased; Pearl assumes that she is Greg's servant ("system/BOOT.pearl_final(3).Info"). With her memories gone, Spinel is a goofy and happy-go-lucky Gem whose function is to entertain her companion. Steven seeks advice from Peridot, Lapis Lazuli, and Bismuth; they try to raise Steven's spirits ("Who We Are"). Bismuth recognizes Spinel's weapon as a "Rejuvenator", a device used to reset the minds of rebellious Gems back to their default state. Spinel compares the situation to a puzzle, suggesting that they find the Gems' "missing pieces" to restore their memories, inspiring Steven to try to reenact Ruby and Sapphire's first fusion. Spinel's antics cause scaffolding to collapse, almost crushing Ruby; when Sapphire shoves her to safety, they fuse into Garnet ("Isn't It Love?"), but she still has no memory of her life.

After Steven recovers Amethyst's memory by reenacting experiences the two had together ("No Matter What"), Peridot discovers that Spinel's drill is injecting a toxic chemical that will kill all life on Earth. In a moment of panic, Steven attempts to remove the injector, but his weakened efforts only serve to accelerate the process. In order to revive Pearl's memory, the group takes her to a Sadie Killer and the Suspects concert, hoping their music will bring back her memories of rebellion ("Disobedient"), but Pearl insists that as long as Greg exists, she will obey him. Steven uses what little energy he has left to fuse with Greg ("Independent Together"), which enables Pearl to recover her memory. She tells Steven that Spinel was once Pink Diamond's playmate; overcome with sadness, Spinel flees.

Steven follows Spinel to a desolate garden in space, where she reveals her backstory: When Pink Diamond began the Gem colonization of Earth and did not want Spinel to join her, she tricked Spinel into "playing a game", in which Spinel was to stand frozen in the garden.

Song 2 other friends: That's right, I heard the story over and over again
Gee, it's swell to finally meet her other friends
That's right, I heard the story, don't really like how it ends
Gee, it's swell to finally meet her other friends
What did she say about me? What did she say?
What did you do without me? What did you do?
Did you play games without me? What did you play?
Did you think all this time that I wouldn't find out about you?
That's right, I heard the story over and over again
Gee, it's swell to finally meet her other friends
She's running circles around us
I'm rusty, give me a break
It really is her, but she can't be serious
You know her, Pearl? Can you tell us who she is?
Who am I? Who am I? What are you even saying?
I'm the loser of the game you didn't know you were playing
Let's play another game, this time I get to win
Lives on the line
Winner takes all
Ready or not
Let's begin
Oh, that's right, I heard the story over and over again
Gee, it's swell to finally beat her other friends
Oh, that's right, I heard the story, don't really like how it ends
Gee, it's swell to finally beat her
Other
Other
Other friends

song 4 change:
[Steven:]
I can make a promise
I can make a plan
I can make a difference
I can take a stand

I can make an effort
If I only understand
That I
I can make a change

Listen to me Spinel! I understand
After everything you've been through

You must be in a lot of pain

[Spinel:]
No... No! You don't understand! You can't change the way I feel

[Steven:]
That's right! Only you can

You can make it different
You can make it right
You can make it better
We don't have to fight

You can make an effort
Starting with tonight
'Cause you
You can make a change
