So, me being the rabid fangirl I am, read it. It mentioned the Philosopher's Stone.
It said that it was a stone that could turn anything into gold. Just gold. It said nothing else.
So... it brought to mind the hilarious mental picture of Manga!Ed and Al finding the stone, using it to bring back their bodies, and then having huge chunks of gold appear instead.
.... No, I'm not on crack. Why do you ask?
