“Foot . . . energy . . . ,” Sophie repeated.
“Yep! Alvar called it ‘full body momentum,’ but that’s boring and
confusing because all it means is: You want some extra oomph, move
your feet. See?”
He shifted his weight onto his other foot at the same time he waved
his hands forward, and Ro shot backward, nearly crashing into the
wall.
“It’s a small thing,” he said. “But that’s the point. Everyone forgets
their feet with telekinesis. They focus on their hands and their arms
and pulling energy from their core. And it doesn’t have to be a big
movement. The tiniest step makes a huge difference. Try it.”
“I’m not allowed to get out of bed,” Sophie reminded him.
“And yet, you’re moving your feet right now.” He pointed to where
her feet were, in fact, fidgeting under the covers.
“Wow—remind me again: Why do so many people think you guys
are so special?” Ro wondered.
“No idea,” Sophie told her.
“Don’t let her fool you, Ro. If Foster used foot energy, she could
smash you through the ceiling.”
“So? It’s all still a party trick. You try something like this in a battle
and you’ll end up with a dagger through the forehead.”
“Not Foster. Foster could catch that dagger and whip it back at you.
Even with only one hand.”
“Pretty sure I couldn’t,” Sophie argued.
“I know you couldn’t,” Ro corrected.
“See, and I know she could,” Keefe insisted. “Especially with a little
foot energy.”
