Locke's backstory just keeps getting more and more bizaare. He goes from working at a toy store to working in a cubicle and his whole deal with his Dad stealing an organ and now we learn that he's worked on some weird drug farm?

I mean. All of the character's stories are kinda out there, but Locke's just keeps getting more and more bizaare everytime he has one. I don't like it. I liked it better when he was just this guy who had big dreams but was hindered by his disability and he worked a normal mundane job.

Also, I had to deal with some roaches during the last few minutes, can anyone explain what Hurley's weird reaction at the end was all about? Did something happen with him and Desmond?
