Also, I want to talk about this:
He loosed the arrow. And I think that by the tricksiness of degrees and prophecies and the fact that Odin is "alive," Loki may have just become the heir. But aside from that, that bow and arrow sure seem to be an All-Weapon. It contains a sort of blessing from all the realms and all the important players, and if this is going the way it seems to be going (that Odin is no longer an end-all, be-all, and therefore no one is, because no one should have been?) then maybe the bow is the sort of weapon of office for a warrior of consent or consensus?
