OK, color me officially confused. I thought we were going to get answers not have more questions?
Here is mine - What the heck is going on with Desmond? It appears he is fully aware of the cross over between Island life and alternative/sideways life. Why then, did he attempt to run down Locke in sideways world? Does he think that killing Locke in sideways life will kill MIB/Locke?
Also, it fully appears that the island is indeed hell. When Hurley was talking to Michael he asks if he can leave. Michael's response was no, because of the things I've done.
Not as in depth as some starting points, but I like reading everyone's thoughts, so let's have at it.
