The Ruby entrusted with bringing back the bubbled Jasper arrived safely on the Homeworld. She handed the Jasper to a waiting Peridot, who handed it to a Agate, then an Emerald, then a Sapphire, then another Ruby, and finally to the Yellow Diamond's Zircon. The Zircon carefully took the bubbled Jasped into the throne room where her boss, the Yellow Diamond, was waiting for her next appointment to begin (in a few Earth hours).
"We recovered Jasper, my Diamond," said the Zircon.
The Yellow Diamond turned to face Zircon and noticed the bubble.
"Hmmm... It looks like Rose Quartz got to her," she said, "I'd recognize that bubble anywhere."
"I've been told Rose Quartz turned it in to one of Blue Diamond's Rubies. It was cracked when it was first given, but then healed by Rose's healing powers before Ruby took off."
"Ah yes, healing," said the Yellow Diamond, "The one thing Rose Quartzes were good for," she began to wonder if disposing of all the Rose Quartzes was a good idea, "Very well: set her on the floor and un-bubble her."
Zircon did as she was told. The bubble popped, Jasper began to levitate, glow, and assume a humanoid form. The traces of corruption, however, were still notable. Jasper looked at herself, then up at the Yellow Diamond.
"Welcome back, Jasper," said the Yellow Diamond, "What happened with your encounter with Rose Quartz?"
Jasper flinched at hearing the last two words of the spoken sentence.
"KILL! ROSE!" she said, deadly and gravely.
"Ugh. You're corrupted! How did that happen?"
"Does Rose Quartz have the power to corrupt?" asked Zircon.
"Nothing that hasn't been documented," said the Diamond, aside to Zircon, "My guess is she came in contact with a corrupt gem during a battle."
"Should've have those corrupted gems shattered in the first place."
"You think?"
The gems turned back to the animate Jasper, running rampant around the room yelling "KILL! ROSE! KILL! ROSE! KILL! ROSE!"
The Yellow Diamond yelled "Jasper" and the orange corrupt gem stopped in her tracks.
"I appreciate and share your disdain in Rose Quartz, but don't you think you're taking it a little too far?"
Jasper's voice only became more and more deeper, "KILL! ROSE! KILL! ROSE!"
"(sigh) This is ridiculous, even for me," said the Yellow Diamond, looking at a watch, "Zircon, take Jasper to a maximum-security cell. We'll deal with her later."
"What about you?"
"I have to go interview more replacements for Pink Diamond."
The Yellow Diamond pressed her giant hand down on Jasper, poofing her. Zircon picked up the poofed gem and quickly headed for the appropriate area.
Re-formed and locked in, Jasper is armed only with a crayon. Her sleeves were attached-sewn-to her top, rendering her arms unable to move. She spent most of the time in her cell using her feet. The crayon lodged between her toes, she kept writing KILL ROSE over and over again all over the walls of the room. And there she remained, never to be disturbed again.
