Scar dropped his sword, vaulting the chair that was his hiding place and lunging for Edward in one fluid motion. He was much less gentle with him than he had been with Korra, though he was still cautious. There wasn't any hesitation. He aimed an elbow for the back of Edward's head, hopefully hard enough to knock him out without causing further damage.

To look on the bright side, he'd done worse to the poor kid.
