Maybe something happens in New Ultimates #4 or #5 to put it back into doubt?
I have no idea, but that's why I interjected into the exchange between you and Sky--whatever "Now" it's supposed to be, he still is being viewed as a loony in it.
Weren't there differences between Ultimates 2 and Ultimates 3 Thors? Subtle ones, did he have a different hammer or something? Maybe this will explain it. A return to Asgard and a sort of reThorification?
Is it me or does the pen "Don Blake" (not convinced it's him) hands him have more runes on it?
