He had no idea who started the fight, the back story to the fight, who was the villain, who was the victim. But he had to protect m'Lady.
There is no reward for White Knighting.
if your choice is to restrain one or the other... restraining the man is the correct choice (assuming he’s not a manlet).
why? an adult male (6’0”+) can EASILY kill a typical adult female (5’5”+) if he tried. people seem to forget this.
as for the male losing consciousness while being restrained... i’m guessing the guy went for a choke hold and didn’t let up in time unless drugs were involved then all bets are off.
of course, i’d prefer a firehose for both to cool things down :)
