Hmm...I find you guys very interesting to read about, I'm gone one night and come back to all these amazing theories~
Anywho...as for the bomb....I heard about this one. How the epitaph was actually supposed to warn you of the bomb, and that the gold was in a bomb shelter so if you found the gold, the bomb wouldn't kill you.
But where did this theory come up from? And who would've planted it on the island? And WHERE could it possibly be hiding? In the well, or in the chapel?
Sorry, I would think it'd be O_O if it was a bomb...People are also saying Yasu was setting it up. But why would she set it up, if she just wanted a friendly fake-mystery game with Battler?
