I thought it would be a good idea to make a thread for the finale before it airs so we can discuss what we think will happen and what unanswered questions we would like to have answered. I would like these questions to be answered. 1. What is the light at the heart of the island? 2. Who built the statue, the temple, and all the other ancient Egyptian structures? 3. Where did Jacob's mother come from? 4. How did Jacob travel to and from the island? 5. What's the deal with Jacob's cabin and the ring of ash that surrounded it? The ashes have been used several times since then. Where did they come from? 6. Why is the island submerged under water in the flash sideways timeline?
