Tomorrow sees Dan Slott's Amazing Spider-Man #698 issue released, and it's said to be a big one!

And it is!

Spoilers for the issue have already landed online!

A user at Reddit posted the page that features the big reveal!

Does this also reveal the identity of Superior Spider-Man? 

A bad guy?

And when did this first take place?
