Jackson kept leaning back, taking another sip from his drink, as the men began spreading out and leering at his companion. The closest one was still a table or two away from her when he decided to speak up, hidden in the shadow to the casual glance. 

"I'd best advise you be stoppin' right there, mate. Wouldn't want to lose a finger, see, and then your arm, and then your head. She's a feisty one, and she'll probably kill you all in about three times the time it would take me to do so... so let's go with about, oh, fifteen seconds?"

The captain turned towards him, opening his foul, rotten mouth to begin speaking, before being interrupted.

"What was that, cap'n crunch? Didn't hear what you said there." 

He got angry, and was about the shout when he interrupted again.

"What?"
A smirk followed.

"What was that you said?"
Jackson was enjoying yourself.

"GET-"
"What was that you was sayin'?"
He just looked about fit to burst.

"Alright cap'n crunch, sit right on down and have a drink on me."
This time, he made no move to stop him as the pirate screamed, "I'LL NOT BE HAVING ANY MORE OF THIS! GET 'EM!"

The first man to rush towards him collapsed soundlessly, the beginning of his warcry dying as fast as his heart, a knife protruding from his chest. And yet, Jackson had barely moved his arm, though he now set his mug down, and stood up. The other pirates all stopped, barely even starting, and Jackson smiled warmly at each one of them, scaring the shit out of them with just his eyes.

"I like to think myself a doctor for hire. I take out the rot in the society, see. Now you all rot, or you all civilized men who deal like 'em?"
