The epilogue cuts back to Mephisto and Doctor Strange in Las Vegas, Mephisto tells Strange to 'stay away from the slots' (OOOOOOHHH), and then offers him another wager: The virtue of a hero for the corruption of a soul.

TO BE CONCLUDED

Trying to sort all this out, here's some thoughts

Given A.I Harry would likely be wired into the internet, he probably figured out Norman was alive by tracking down assets and other projects that involved dealings with him during his European exile. Hell, AI Harry is based in Europe also, or maybe having Norman's brain waves as well as Harrys' somehow gave him that sort of second sight

So with Harry possessing Sarah...does that now mean the scene in "Sins Remembered" where Sarah kissed Peter, was Harry making out with him?

And at least with Mary Jane, you can now write off any time she's acted out-of-character by saying it's because of 'bad therapy' with Mysterio. Totally ruins their friendship of course and makes Mysterio a serial mind-rapist, but it's one out to consider
