With Lost's sophomore year coming to a close tonight, producers have promised viewers that many questions will be answered. In what surely will be a dramatic finale, what mysteries will unravel and what will remain unknown?

There are many questions that we hope will be answered, but for now, we will be happy with insight on the following:
