has Sawyer ever introduced himself to the Dharma people as James ?
because Jack asks, "where does james lefleur live?"
and the guy says, "don't call him jamesm he doesn't like that"
I was thinking sawyer has never used the name james, and so when jack referred to him by it, it showed they know each other and that sawyer (lefluer) has been using a false name
the creepy guy realized all this very quickly and made up the little story of lefluer not liking the name james only so jack would not refer to him that away again
because if jack did refer to him that way again, lefluer would tell jack, "they don't know me as james, so don't use that name"
and then jack would say, "but I already have so they might already suspect"
but now that creppy guy has told jack not to refer to lefluer as james,
lefluer will never have the chance to tell jack that dharma doesn't know him as james, so jck and sawer will never figure out creepy guy knows something is going on
does that make any sense?
