Something from the revised version of the first "Angel of..." story which becomes pertinent in the one I'm working on:

She chopped a few carrots, then thought of something. Melody caught Aaron's eye.

"Which brings up something I've asked about before, but not actually asked _you_ about. How do you - you, personally, and those you work with - manage to get so much done? I mean, even with superhuman intelligence, physical acts still take a finite amount of time. Arielle said something about you being able to boost your speed, but I don't..."

Aaron grinned impishly and held out his hand.

"Oh, explaining that part is easy. I can even show you."

Melody looked warily over at Arielle, who was sitting on an adjacent bar stool, another cutting board and knife in front of her, preparing onions. She was grinning like a kid about to see something fun. A bit reluctantly, the reporter put down her knife and took the empowered man's hand.

Sound was suddenly distorted. Melody looked around, feeling disoriented. She noticed that Arielle had suddenly stopped moving, and seemed frozen in place, mischievous smile still on her face. A glance out the closest window showed no movement in the yard beyond, except for a bird flying by in no hurry at all, its wings flapping very slowly.

"I can push the time distortion much further than this, but I think this is enough to make my point," said Aaron.

With his free hand he lifted one of the uncut carrots to shoulder height and released it, quickly pulling his hand back. The peeled vegetable began to fall, but slowly.

"Even at this low level of acceleration the speed of sound becomes a significant barrier to communication. If we weren't both in the same bubble there would be a noticeable lag in our speech, back and forth."

He grabbed the carrot and released Melody's hand. Sound came rushing back in, and the bird flew away. Arielle finished reaching for another onion, still smirking.

"So," said Arielle, impishly, "how was your first experience with accelerated time?"

"Unsettling. Though that does answer many questions. Especially if the effect can affect multiple people, and if he can maintain it without touching them."
