Charlie's Lost--part 2

Okay, I've kept thinking about that episode of Lost since last night because it was bugging me I couldn't get a handle on it. Obviously this is about a pattern Charlie has in his life that he's got to confront or fix or break out of, but I couldn't figure out what it was *about* exactly. But this morning I had some ideas in the shower that made the ep a lot more interesting, ( especially with regards to Eko and Locke. )
