Hmm, that's a good theory misspiggy. Showing the video of a time-travelling bunny, while interesting and slightly connected to past episodes, didn't hold much relevance to me at that point in time.
However, connected to a theory of moving the island through Time as opposed to space, rather than both time AND space does throw in to centre stage a bit more.
However, I wonder if where Ben goes holds any relevance upon the island's new whereabouts?
