Something doesn't make sense about this at all, especially since as recently as issue 71 we had this scene of Kindred reflecting on a moment between him and Peter as Harry:
I mean, even if Kindred was supposed to be Harry when Last Remains was written, and Spencer was forced to change it sometime after, why add a scene as late as issue 71 that just reflects Kindred believing he is Harry? If Spencer had to change the story, he should be working on making Harry be just a deception, not Kindred actually believing he is Harry and thinking about stuff only Harry and Peter would know.
Also, how in the world would Spencer ever explain away the intimate details and inside knowledge Kindred has about Harry from Last Remains, the dream sequence between Peter and Harry from OMD, the fact Kindred is watching over his wife Liz and son, Normie? That whole arc would not make sense and be a huge senseless waste of time.... How do you explain that away? These leaks make the entire run utter nonsense. The "true" Kindred(s) have terrible motivation to even go after Peter, as it was all Norman they should be pissed about. If this leak is true, I'm done with Spider-Man I have no interest in spending money on such a terrible story and incoherent plot, talk about ruining and entire run with things that make no sense.
I really hope this is fake news.
