The raiders sit there, drinking and chatting away. It is clear they are both fairly drunk. It seems they have not yet noticed our intrepid adventurers. One of them gets up and walks to the edge of the tree line to the bush Rodney is hiding in and proceeds to urinate all over it, covering Rodney in raider piss. He drunkenly staggers back to the fire and takes a seat again, oblivious to his surroundings. They both start singing a song, holding up their drinks, singing out of tune.
