Did you notice that the pawnshop owner has some sort of disability? Feed him some of the drugs, one will help him.
I don't know about having patience, but I got down to needing 5 more points ......... grrr. I found them at the drugstore by getting annoyed.
I had bought every drug
listed so tried buying other things that he may have. What item (not a drug) would James perhaps buy at a chemist? The other thing that gave me a clue was the fact that James was about to become a Gang Member. What sort of activities are gangs often involved with? Can't see a Chemist stocking such stuff .... however, it worked.
