Steven Universe, Season 3

[After briefly fusing with a corrupted Gem, the corruption spreads slowly in Jasper's left arm]

Peridot:
Eww, that's disgusting!

Smoky:
It's... corruption. [separates back into Steven and Amethyst]

Amethyst:
Steven, be careful.

Steven:
But this just happened - maybe I can do something! Jasper, it's okay. I'm here. [starts approaching her]

Jasper:
[snarling] Rose...

Steven:
I'm not Rose, I'm Steven. I just wanna try and heal you. [licks his palm and reaches for her - but she slashes at him, tearing his shirt]

Amethyst:
Steven!!

[Peridot unsuccessfully tries to mentally move the metal rod again]

Steven:
[as Amethyst tries to charge at Jasper] Stop!

Jasper:
[chuckles] I see how you do it now, Rose. You want Gems after they're worthless. You wait until after they've lost. Because when you're at the bottom, you'll follow anyone that makes you feel like less of a failure. [as Peridot rushes over] Huh... Just look at this one! You've stripped her of everything! Her limb enhancers, her status, her dignity...

Peridot:
I still have one of those things.

Jasper:
How can you side with Rose Quartz?! Why? Why protect this useless shell of a planet?!

Peridot:
It's not a shell. There's so much life, living here. [smiling] That's what I'm doing! I'm living here! I've been learning new things about myself all the time! Like how I can make metal do my bidding! [tries to show this off, but the rod just falls behind her] The point being: Earth can set you free. [Steven smiles]

Jasper:
[angrily, as the corruption spreads rapidly in her body] Earth... is a prison! I got out because I'm better than this place!

Steven:
It's getting worse.

Jasper:
I only came back to finish you off.

Steven:
Try not to move!

Jasper:
You can't manipulate me, Rose Quartz!

Steven:
I-- I'm not manipulating! I'm trying to help!

Jasper:
Help? HELP?! I've been fighting from the second I broke free of the Earth's crust! Because of what YOU did to my colony! Because of what YOU did to my planet! Because of what YOU did to my Diamond!

Steven:
[confused] I... Yellow Diamond?

Jasper:
Wha...?! MY DIAMOND! YOUR DIAMOND! PINK DIAMOND!!! [becomes fully corrupted, barely recognizable, and looks ready to attack; Peridot finally gets the metal rod to move, plunging it into Jasper and making her poof]

Peridot:
[after a brief silence] You're... welcome.

Amethyst:
[smiles, then walks over to Jasper's gem and sighs] Come here, sis. [bubbles her]
