Dying in Dr. Octopus' body, Spidey confronts Ock (in his body) one last time. Peter is unable to transfer his consciousness back, but as his life flashes before his eyes Ock receives them as well via their mental link, with himself in place of Peter in them.
Ock (still in Spidey's body) tells Spidey he doesn't want this, and asks how he can do what Spidey does. Spidey (in Ock's body) tells him that he has to, because with great power...
But "Ock" is dead.
While this will probably last as long as Captain America's death did, I actually like the idea of a (reformed?) Ock as Spider-Man. I think there's a lot of potential with this idea and I'm definitely on board for Superior Spider-Man.
So I'm surprised to say this, but kudos to Slott. I'm looking forward to see where Ock!Spidey goes from here.
EDIT: There's an interesting write-up here.
