The boy on the steps
When John is delivering newspapers, and encounters the new boy on the steps, is this boy the Canta character who threatened him earlier?
If so, why does he want his fellow-neds to beat him up (or allow John to beat him up, I didn't altogether follow the discussion they had about this new kid in the neighbourhood)?
Had not big brother Ben and a colleague dealt with Canta earlier, and John had shaken his head, to spare Canta a worse hiding? Surely this should have ended the beef between John and Canta? Why the need to beat him up again years later?
