The premise of Spider-men is that Miles is meeting the peter from another universe. Alonso has told me the fact that 616 Parker looks like ultimate peter but isn't him is part of the story. Then later you remember there is spider-woman who is more like peter than 616 as she has his memories. Marvel is only glossing over her because she is female. If she were Ben Reilly this Spider-men story wouldn't even be happening! It makes the story seem more forced than ever when you realize Miles can learn so much more from someone in the same universe.
