Lost - Secrets

I don't have a clue. Really. But I have some ideas. 1) women who are pregnant die on the island maybe because of the strong magnetic field it produces 2) i have no idea really what or who jacob is, but I believe he is behind the island's manifestations. Like jack's father, hurley's friend dave and eko's brother 3) I think everything we have seen is one big flash back. What we saw in the finale is now time. 4) Penny is looking for desmond at the same time her father is. But for different reasons. Hence how Naomi knew about desmond and penny. Other than that. I really don't know. I just enjoy watching it all unfold.
