yeah, there was a panel where Osbourne was talking to him as Peter Parker and he's relieved that Norman doesn't know his identity because of something "we" did.
But since he doesn't seem to remember BND that seems to be it.
you know something just occured to me.
What if he does remember making a deal with Mephisto. If Pete and MJ basically lived as husband and wife for years without being married then OMD must have happened very similarly.
What if Mephisto fucked with Peter's memory and made him think that he and MJ gave up their love for erasing the memory of Peter's identity from people's minds. Instead of their marriage for Aunt May's life. That way there's no trying to renege on the deal.
