"Too right mate. Too right. Remember those two munters Sid brought to back with us after? The fat one broke his bed and when he tried chuck 'er out she was sick in his snare drum. Now that was a party.
The conditions of the last year had been hideous, trapped deep in the earth, seeing the same people day in day out, not knowing if all of civilization had been destroyed and last but not least, eating a friend. Seemingly returning to some semblance of normality once free from the metal tomb that had saved his life, the Englishman turned to the two outsiders.
"Sorry to be abrupt just now, you know what its like when you've been trapped deep in the earth, awaiting uncertain death for a year."
He laughed then and a fair judge would say it was not hysterical, but only just. He composed himself and said
"My names John. John Utland. So the big question now is what the fuck do we do? Stay here or leg it? Personally, I vote that we fuck off sharpish."
Hearing a cry in the distance, John pulled a worn .22 pistol from a holster hidden in the small of his back.
((Um, so I should probably say a few basic facts about my character, because Gavin and John obviously know each other from before and LordBucket has been trapped with us for a year and we obviously would have talked all about ourselves out sheer of boredom if nothing else. Basically, I'm not a member of Gavin's band but an old friend and drug dealer. I don't want to impose anything on your character hubris_incalculable, i.e. that your character takes drugs, but nor do I find it unreasonable that a mid eighties punk band touring America would invite along their drug dealer friend. Incidentally, while I was thinking all this through, I realised that we are in the right time period for your character to claim to have invented straightedge, although back then it was more "no booze or drugs, only sex AND fighting like a crazy man.
Basically, I'm taking a leaf out of Lordbucket's book and playing myself, but if I was as old as I am now (24) in 1982, hadn't decided as a young man that selling drugs was an overly stressful career path and had by luck survived the alt-history apocalypse. Gah! EDIT due to ninja action.))
