he is just not going by the name donald blake and not being the whole dr. blake deal. He is probably just goes by thor which is likely only thing he remembers of himself. Then he grows and changes with his interactions with humans and jane. i dont know much on thor myself so i dont know how they are going to go about it. But like i said i still think the blake name will get a mention in there. Like maybe a scene with jane saying thor should call himself a different name since thor sounds so strange, or maybe the name will get a nod like a cross section street names(like just image stan lee creates superman did clark kent lol) or maybe over an intercom in any hospital/what not scene we hear someone calling for a donald blake.
