"By the way, does anybody know what exactly happened to Walt?"
I don't remember the details but he's in Doc Samson's body while Doc Samson is in Walt's. That's why Sasquatch is now called Doc Sasquatch when he shows up. This is not a story plot that I enjoy and hope it gets reversed sometime soon. I enjoyed Immortal Hulk quite a bit other than that whole thing with Doc and Walt.
