Wrong. Jim is supposed to be extremely clever, and growing botulinum can be done. It’s one of the dangers of canning meats at home, in fact, and, unfortunately, happens now and again. He would need meat, and the right conditions, and he could grow it himself. This assumption is therefore a logical fallacy.
Also, “therefore, Jim had help.”
Head canon rejected. Moriarty is a genius and doesn’t need outside help.
