[D-Roc]

This is certainly one of the most interesting aspects of the episode for me - upon watching the episode again, I notice that only Hugo seems indifferent to referring to him as Jeremy Bentham - he asks Hurley why he doesn't just call him by his normal name - which could suggest that doing so would either compromise Locke/Island or compromise them..

It's almost as if the island or the manifestations/spirits are observing everything that goes on and so they have to use code-name in order to refer to Locke.

Or perhaps this is literally a different iteration (incarnation/loop) of 'Locke' - an angle strengthened by 'Cabin Fever'.

Just some suggestions - it will be interesting to find out what went down on "craphole" after Jack left - apparently some REALLY bad stuff happened.

Also, it's perhaps worth noting that Locke/Bentham first came to see Jack and Kate a month before his 'funeral' (according to Jack..who was stoned). Could help shed some light on time-line etc.
