The gems teleported to Home world and tell Spinel  and the Diamonds what happened. 

Spinel: What?!

She was surprised.

 Spinel: How?! Why?! Did we do something?! 

The diamonds looked at each other, and then, Yellow Diamond speaked. 

Yellow Diamond: We can't uncorrupt him.  

Connie: What?! There's gotta be a way to take him back! 

Then, Amathyst looked at the Diamonds. 

Amathyst: Steven uncorrupts gems in the bathroom! You can do the same, right? 

White diamond looked at Amathyst and answered. 

White Diamond: To uncorrupt him, we need his essence too, but we only have our essences. Without his essence we can't do anything. Im sorry. 

Lapis: There's gotta be another way! 

Blue Diamond taked three bottles of different colors: blue, yellow and white. Then, she gave the bottles to them. 

Blue Diamond: These are our essences. I think if we find a place where we can take his essence in another state, it may works. We can't go with you, but we can search in Homeworld, right? 

She looked at the two other Diamonds: Yellow and White, who nooded. 

Garnet: Then, we'll search in the earth. 

Spinel: I'll go with you! Pink Diamond told me some things about her colony, so maybe I can help you. 

Garnet looked at the group. 

Garnet: Alright. Then, Bismuth, Lapis, Peridot and Spinel, you'll look in the Kindergardens Prime and Beta.

They all nooded. 

Garnet: Pearl, Amathyst, Connie and I we'll go to the Wattermelon Island. 

They all used the portal to go to the temple, and then, to their destiny.
