After finishing "Ultimate Spider-Man: Ultimatum", volume 22 in trade, I'm thinking I may have missed something, like, how'd Pete lose his mask, only to be found by Kitty and Jessica? I have yet to read "Ultimatum: Requiem", but I have it coming. Will that explain this, or will the actual event comic, "Ultimatum"? Or will it be revealed what happens in "The World According to Peter Parker", the first volume after the renumbering?
