This is for anyone who bought the complete series on DVD or Blue-Ray. The other day, I was looking through all of the stuff you get with the DVDs. On the lid, there is Rousseau's map of the island. I twisted it, and took the map off. Underneath, there was a golden disk. It looks really interesting. I don't know if any of you have found this yet, I got my box set on the first day it came out, and I just found it. Anyway, I don't plan to find out what's on it until I finish my rewatch.
