Ah, yeah, it seems I pretty much understood it too, then. Makes sense. The fist does glow gold, it sorta looks like a key, and they always made such a huge point out of Danny Being a Weapon/Tool. So his being a key at the very least made sense, though it made me feel kinda bad for him.

To be entirely fair to Danny, the whole thing WAS damn confusing, and also they needed to throw him the Idiot Ball. Dude got screwed when it came to getting thrown the Idiot Ball.
