"You sure?" Dave asked, looking off into the distance, away from her. The light of the rainbow ocean reflected off his sunglasses. Behind him, Rose gave a smile just shy of smug. Her needles dangled loosely in her hands, pulsing with the dark energy she had grown so familiar with.
"It's within your abilities, isn't it? Or have I overestimated the powers of a coolkid. Perhaps I overestimated your coolness itself, bedazzled by nought but a mere facade."
Dave didn't answer that. Rose knew she couldn't get a rise out of him, not like that. It was one of the reasons she loved him so dearly.
"I don't go messing in your grimdark bookishness, do I?" he retorted after a moment. "The thing is, I don't remember an extra Rose running around. That much snark would produce a snark black hole. Freaking sarcasm particles flying everywhere and all that pseudoscience shit."
"A snark singularity? Would it be orbited by contemptuous comets? Is passive-aggressive simply the superposition of the two states?"
"What kind of land always rains anyway?" Dave asked, kicking at the white sand. "Needs more gears and lava. That's badass. This is, like, sissy land."
"The fact of the matter is that I either covered my tracks well enough to maintain causality, or I create a divergent timeline. In which case we've already effectively diverted, since you are going to take me back. So there's no need to worry."
Dave appeared to be looking down, but it was hard to tell - just the slightest cock of his head. "Yeah, okay." he said. A pair of turntables appeared in midair, and he laid his hands over them. Rose stepped in close, and gave another close-lipped smile. Dave stayed silent, still, and from this angle Rose could see his eyes were on the horizon, as if he was elsewhere even now.
In a flash, they were back in time. To near the very beginning of the game - they weren't sure how the timestream of skaia related to that of Earth's, but Dave wasn't willing to bring her back before hand, muttering something about "keeping it sane".
"Thank you Dave." Rose said, reaching up and laying a hand on his shoulder. He turned to her, and for once, lowered his glasses. Looking him straight in the eyes was so strange, so unexpected, that even Rose had to pause, her mind going still.
"Stay out of trouble." he said. He was gone in a flash. Rose hadn't even seen him move, let alone the turntables. She smiled. He was sweet - but it was better that he wasn't around for this. Rose knew, one way or another, that her time could well come to a close soon. This could be an alternate timeline, but even if it wasn't, she could die trying to cause the scratch, or succeed only to not avoid the "reset" it would provide....so Rose wanted a day to herself. A last day, like a death row inmate getting a last meal, where she could finally get what she had always wanted. She was by the turtles' library, hours ahead of her past self. There was a lot there on dark magic, and Rose could now study a very interesting book she had spotted but not, until now, had time for. A very interesting book about manipulating the body....
