Re-watching is so great because you get to go back and see the characters do and say things that you totally forgot about because the first time around it did not seem that important. Like I forgot that House of the Rising Sun was the episode in which they find Adam and Eve. Towards the end of the episode, Jack comes to Kate on the beach to get her decision as to whether or not she will come to the caves with him and Kate says, "I don't wanna be Eve." For me that pretty much settles it, Jack and Kate are Adam and Eve. From a story telling standpoint, I don't see how they could come up with anything more ironic.
