An hour in, and Jace was still standing tall. Sweat dripped down his jaw, his shirt stuck to his back, but his breathing was steady.
Eva, by contrast, leaned forward with her hands braced on her knees, catching her breath.
Her hair clung damp to her temples, and frustration flashed in her eyes every time she glanced at him.
"You've gotta be kidding me," she muttered. "You're not even winded?"
Jace shrugged, rolling his shoulders. "Not really."
[Of course not,] Zin chimed in. [His ability is kinetic at the core. Every bit of movement generates fuel for his system. Where a normal body loses energy, his recycles it back. The more he moves, the more stable he stays. It doesn't mean infinite stamina, but it keeps him going far longer than any baseline human.]
Eva shot Jace a sharp look, her tone edged with bitterness. "Yeah, I know. It used to be my body running like that, remember?"
