Agreed. It's been made abundantly clear that Rosalind is Thor. No one has the level of knowledge of Dario Agger that Roz has. She wasn't created in God of Thunder just to be a red herring.
Edit: Also, Aaron loves to have mouthpieces in his stories and from day one Rosalind Solomon has been Aaron's mouthpiece for environmentalism. Both Roz and Thor are constantly going on about protecting the Earth - they are the same person.
