Exar almost laughed at hearing her gasp, but the amusement in his gaze made it clear enough. She'd need to try harder if she was even trying to convince him.
He was about to retort when he felt his hand pinned against her back by a kind of rubber, driving his fingers in deeper. Exar snarled at that treachery, face contorted in rage, and tried wresting it out of the now-rigid fabric. He whirled his left arm with the saber up, instinctively ready to lash and kill the creature with a long slash to the head, but her grip was quickly upon his hand, restraining his arm in mid-swing. The creature's actual strength became evident to him in that moment, and he guessed it could snap his arm like a twig if it truly wanted to. Unable to move either arm and losing control, he began to panic, though that panic only fed his rage.
“Let me go!” Exar roared, his voice unnaturally echoing over the rooftop. He strained his arm up, intent on keeping his saber out of her grasp.
Her remark added salt into his already wounded pride. He couldn't restrain himself any longer; he was tired of being trapped, left helpless to the manipulations of others, only to be forced to beg for his life on their terms. No more. Kun leered back defiantly and gathered the Force to him, concentrating all his rage on the that focus of power within the shapechanger, and then tore his rightful prize right out of her back. Once in his palm, the amulet added greater momentum to his movements, and he felt more powerful than ever, capable of surmounting any challenge in his way, present company included.
Exar lifted his freed hand and twisted the amulet's chain around two of his fingers to secure it, then opened his palm. The saber flew from his still restrained left hand to the right one with the amulet, hilt clinking firmly against the amulet.
"I'm in control," he said stridently, turning into her grip and lunging to his left. The unmistakable blue glow of his lightsaber's blade followed, cutting clean through her arm just above the elbow with a hiss.
