I should point out that he turned and ran into the next room after attacking Zitka.  (Though admittedly, I think she was free enough to make an opportunity attack at that point...)<br/><br/>As for nonlethal damage, I'm tempted to go with 4E's system of "whoever deals the killing blow can decide that it's nonlethal damage".  Not as realistic, but a hell of a lot easier to run rules-wise.
