So Peter was really Doc OCK this whole time Wait What....

So I was reading the latest Spider-Man Comic and at the end of the book this happened. 

Just Read it if you can. 

To explain the back story here Doc Ock is dying and has found out who Spider-Man really is so he has requested for Peter Parker. So Spidy goes to the island where they keep the super-criminals The Lizard,The Spider slayer,Doctor Morbius the living vampire etc. Meets up with The Avengers and ends up here. 

So It turns out that Somewhere along the way is the last few months Doc Ock switched places with Peter somehow and has been Spider-Man, They haven't said how this happened it just did. Then After Spider-Man/Doc OCK explains this Doc OCK/Peter Parker DIES........

SOMEONE PLEASE EXPLAIN THIS TO ME...........
