Hehe, this reminds me of when Babylon 5 was on, and it was on earlier in the UK than here. I totally avoided all internet discussion until the season was over cuz our cousins over there in the islands were constantly doing spoiler-filled chatter.

Also, I don't know why you think there are two islands? That's a supposition, not proven. They could easily be on the same one, hidden, they haven't explored the whole island yet, have they?
