Jaina's movements were a veritable blur, her strikes as seemingly random as her brother's, yet somehow managing to be the exact opposite. When Jacen went low, she aimed high. She stayed in constant motion, too, relying on her smaller stature and repeating the teachings of Boba Fett in her mind.
A reaction was, she assumed, something Kun was expecting. A vow that he'd never harm her family again. Anger that he had stated he would. Instead, Jaina allowed his words to roll off of her. She didn't gloat, she didn't frown, she simply put her training to good use and fought.
"Y'know, Kun," she finally spoke, her voice steady. Almost monotonous. "You talk too much."
Then her lightsaber was in her artificial hand and her other hand shot out. A light post ripped out of the ground from a few feet away and made a beeline for Kun. Jaina, meanwhile, Force jumped into the air - well over his much taller frame - landed easily beside her brother and resumed her attack with clearly random strikes, jabs, and swipes of her violet-colored blade.
