I agree there is definitely information missing to draw conclusions to parts of the story yet to be addressed. I respect your point of view and agree to disagree on the theories. Hopefully at the most, this thread has sparked some curiosity about Phoenix and desire to continue integrating avatars into the storyline (sans Odin, he's got enough story related matter). They've never responded regarding summoning her and I think it would be an interesting avatar to have down the line.
