Yes, i found it strange how the O6 were referring to 'Jeremy' as if he's this mysterious, all-powerful human being, when it's just plain old Locke. Very strange indeed. It makes me wonder what on earth Locke gets up to for the 2-3 years or so after the crash.
Lol when i got in earlier my flatmate (who had just finished watching the episode) came running at me going "Omg i studied Jeremy Bentham in Criminology!!" lol...so she was telling me about the real Jeremy Bentham, and in turn i told her about the real John Locke from my psychology classes. It was very interesting! All i remember about this Bentham guy is that he had something to do with punishment...lol...
This might help.
