As quickly as Topaz appeared, she vanished. She and the mattress disappeared into the heavens in a beam of light.
Steven looked around at the Gems. "What just happened?"
"Let's go," Garnet commanded. She wasted no time hopping onto the warp pad. The rest followed suit, and let their leader take them wherever she pleased.
In a nauseating flash, things were suddenly very cold and dark. Steven looked around and saw the stars over the horizon, over the wide expanse of flat land that was sporadically populated with natural rocky monuments. In front of them, at the base of the steps leading up to the warp pad they were on, began a great canyon that also stretched to the horizon. One squinting look at the decapitated Gem injectors in it and Steven suddenly knew where they were. He didn't know there was a second warp that led here.
Garnet stepped down, and jumped into the canyon. Only mildly surprised, Steven walked down from the warp and, getting down on his knees, peered over the cliff's edge. He recoiled. On the precipice was Topaz hanging by her sword. From her other hand dangled the mattress. Also hanging from the cliff, coolly staring her in the face, was Garnet.
Aggressively, Topaz climbed up with the mattress. Garnet offered to help her carry it up, but Topaz ignored her and did it herself. She dropped the mattress into the dirt, and dropped herself on top of it.
Topaz pulled something from her headband, small and black. She fiddled with it a moment, before Garnet went over to her and knelt. She reached for Topaz's ear, but Topaz pulled away, grimacing hard. This happened one more time, until Topaz's head was on the edge of the mattress and her body was bent into a funny curve.
It was then that Steven noticed, even in the low light made by Pearl's Gem, against the pale color of the mattress, a long black cord running from Topaz's head to her fist.
"Why did you run from us?" Garnet said curtly. Topaz disobediently made a circle on her device with her thumb. "Answer."
"Garnet!" She had flipped Topaz off her mattress.
Topaz, ears unplugged, shot back up to Garnet, who lifted her mattress above her head. "Stop!" she demanded. "Give it back!" Topaz wasn't tall enough to reach it.
Steven looked up at Pearl and asked, "Are we children?" Then he snapped, "Garnet!"
After a moment, Garnet lowered the mattress and Topaz snatched it back.
She asked again, "Why did you run from us?"
"Go on. Git!"
"Not until you tell us wh-"
"So I wouldn't have to deal with you!" She snorted. "If I had stayed: 'What are you doing?' 'Where are you going?'" Topaz shook her head. "Satisfied? You're nothing but trouble."
Garnet stared her down. "And the mattress."
Topaz resigned to snappy responses. "I wanted a bed."
"Why were-"
"I needed accessories for my bed."
Topaz let her mattress fall to the ground. She looked around behind her for her MP3 player. "Tried to stay far away from you, but, apparently, it wasn't far enough."
Steven thought of the distance she would've had to have walked. He crept over to Topaz, aware of personal space, and squatted with her. "Wh-why, uh, did you need to take... the mattress with you?"
Topaz found her MP3 player. She looked at Steven, got up, and walked over to him. Steven fell onto his bottom. He wasn't tall enough to reach her. "I'm not part of your universe. And you're not part of mine."
Topaz went over to the cliff's edge and stuck her earbuds back in.
"Come on, Steven," said Garnet. He followed the Gems up onto the warp pad. Suddenly, the sun was beaming again, and the air smelled of essential oils.
