You screwed me!
Paolo was where you said he'd be, alone. We knifed him fifty times. He was choking blood when I drove a rail spike through the side of his head. Then he was just gone, and there weren't nothing but a bunch of rats. Not sure how he pulled that trick, but you musta known, scumbag.
Next day, Paolo came back with ten Howlers. Got us a couple at a time. Dragged Brynda and Toma screaming into the street and bashed out all their teeth with a hammer. Put that crazy powder in their eyes. Had 'em seeing terrible things, screaming like carnival clowns, mouths all runnin' red. Then Paolo gave the word and they shot 'em with those screaming darts they use. I stayed hid.
So I'm finished, asshole. And I bet you were working with the Howlers all along. I swear, if I ever see you again, I'll stick you.
