@asgaard: Hi asgaard! You're really prolific, it's cool. :)
Here's my "humble" point of view :
From the beginning Aaron didn't stick with the continuity. People didn't care, because Aaron is a good story teller and Thor looked badass. But we were already far, far away the Thor that Stan Lee and Jack Kirby created (the one who is my favorite super hero).
When Thor was created, at the early beginning, the writers let us thought that Donald Blake was a human who inherited the power of Thor from Mjolnir.
Maybe because the soul and the power of Thor resided in the hammer.
My guess :
I think this is the approach that Aaron wants to use. He doesn't care about continuity and wants to tell his own vision of Thor and Mjolnir.
I wouldn't be suprised if it turns out that Odinson was a vessel created by Odin for the soul of Thor residing in Mjolnir.
Ps : From my point of view, the inscription on Mjolnir was altered by one of the best Thor artist to create Beta Ray Bill. ;(
i think at the beginning it was just there to let Donald Blake thinks he was a human worthy of Mjolnir.
you are right, i like the idea of Odin and Cul as brothers like Loki and Thor but you are right
I always thought it would have been better if Cul was just the step-brother of Odin.
