Karr saw stars, no joke or exaggeration, as that fist connected with his face. The fact that his cheek bone did not shatter was something of a shock to Karr. The punch would leave him with a complex bruise, a black eye as well as dark discoloration down the entire let side of his face, those would begin to show in a matter of minutes and vanish within the hour, thanks to his healing factor. That did not mean it did not hurt. His brain likely rattled around in his skull a time or two from the force of the impact.
Too momentarily dazed to work his legs, Karr crumpled to the ground in what was likely highly rewarding for Logan. His claws even retracted of their own will. The teenager growled quietly in his chest as his ego attempted to heal itself, not nearly so fast to repair as his skin was. One hand went to his face as he gritted his teeth, a few felt a rather loose, he noted, and glared up at the older man. "'M not yer solider," he bit rather bitterly out. The pain had done him some good, it had at least taken the edge off his rage. Was he ready to listen? Likely not, Karr was never ready to listen, but he had at least shut up for the moment, and was not taking mad swings at his father. Progress sometimes came in odd forms.
