The Soldier sets the big guy down. Not necessarily gently, but not in a way that will break anything of Gold's, or (less importantly) of the goon's. Then he backs up a step, leaning to avoid the expected retaliation of a nearly panicked swung fist, and to put him more solidly between Gold and his attacker.

The goon looks between the two, mouth agape with mixed belief and outrage. It might even be funny if he weren't a threat. (A pathetic threat, but still.)

Without a word, he points with the butt of the pistol towards the door. After you, asshole. If he has to grab an arm and haul, he will.
