((Oh yeah. Had a derp-brain moment and completely forgot you knocked. XD ))
The clanging of plates as Elizabeth cleaned up muffled the knocks from the other side of the door as Billy grasped the doorknob and opened it. The sight of a stranger standing in the doorway made him jump and immediately draw his two pistols from their holsters on his hips, clicking them into a fire-ready position and pointing them at the stranger. It was merely a reflex, triggered by his startle and by his paranoidness of the law. "Alright, you tell me, who the Hell you are before I blow your brains all over this damn porch." He threatened, clenching his teeth and moving his index fingers off the trigger guard and to the trigger.
Before the two had any chance for further action or words, Elizabeth's scream snagged Billy's attention. Completely disregarding the stranger, he spun around and hurried into the house to find her abusive husband standing over her. "I'd do well to back away from the lady." Billy shouted to get his attention, aiming both pistols at the man once again.
('pologize for the bit of language. It's just his personality.
