She'd almost forgotten how maddeningly calm Jacen could be when preparing to duel. She knew, once he got started, he often grew frustrated and would lose his temper more often than not, but getting him to that point often caused her to lose her own temper in the process. It was one of her greatest weaknesses - and one of the things Boba Fett had worked hard to teach her how to overcome it. So rather than simply charging at her brother and allowing her anger to give him the upper hand, she instead began to calmly circle around him, her lightsaber still held by only her flesh hand and her attention focused entirely on the man in front of her.
"As you wish, brother," she replied in a similarly calm tone, although her lips quirked upward into a hint of a smirk as she advanced. Her other hand finally grasped the handle as well as she turned into a half-spin, her lightsaber at long last striking forward with the intent to deliver the first blow of a battle they'd spent a lifetime building toward.
