"No. I'm going to be better." Starkiller declared. He was going to be even better than his master someday. The galaxy would tremble in fear of his power, when he became a Sith. That was for sure, and what his master told him. "I don't want to do things their way." But also, he wasn't sure what way he wanted to do things when he helped his master remove the Emperor. Then they would rule in his stead. Starkiller was certain that his master would rule differently than the Emperor. Why else would he want to remove the man, and place himself into power.
While her punch would have worked, possibly, Starkiller laughed softly. "No." His laugh was fun, and not even teasing. "Let me help you a bit.." Starkiller helped her get positioned right and explained how to strike. Of course, her hits wouldn't be the same as his, but she could at least defend herself better than that what he just saw. It was fun to have this friend to teach, at least!
