Wow. This episode was very interesting. I loved it. Definitely one of my favorite.
I knew Hurley wouldn't let me down. His flashbacks were once again brilliant. The big twist is something that if you don't read spoilers well.. it definitely will blow your head off. I can tell, It did blow mine. On this island, as Hurley sees his 'friend', he starts believeing that he is only imaging the whole thing. And nothing's obvious. What if..? But no... but if... And at the end, when you think, it's all done, the writers throw in a cliffhanger. A cliffhanger that was absolutely unexcepted.
