Knock his ass out.

"You shut your God damn mouth!" You snarl. "Or I will shut it for you."

Keith laughs and folds his arms, towering over you. "I'd like to see you try, slick. C'mon give me your best shot." You're so pissed right now, you don't even know what you're doing. You draw your right fist back menacingly, then quickly jab his stomach with your left fist. His eyes trained on your right hand, Keith didn't see your suckerpunch coming and doubles over in surprised pain. You let your right hook go free and clock him on the jaw.

You never considered yourself an especially strong person. You're can lift heavy objects and easily carry Melody around, but you never expected to be able to lay someone out with one hit before.

Never underestimate the power of pure, unadultered anger. You can almost feel Keith's jaw pop from your hit and he falls back flat on his ass, his eyes closed. Your fist hurts like hell, and you hope to God you didn't break any bones.

"Oh my God!" Tiffany shreiks, looking down at Keith's body. "Keith! Baby!"

"Errr..." You say as you notice how everyone is looking at you. Melody is staring at you in a kind of muted wonder. Whether she's grateful or horrified at your violent action has yet to be seen, but you at least know she's looking at you in awe. She probably never thought you were capable of that. "We should go." You say and grab Melody's hand. You throw some money down on the bar for Shamus and head for the door. Behind you, you hear Keith groan as he starts to come to. You just know he's gonna be pissed. You got in a good hit, but you don't think you could last in a real fight. It's best to try and run at this point.
