Not for Cale, but for those he cares for. He will take the burden of secrets from Cale’s shoulders, if only to lighten the heavy load he tries to carry on his own.
Or Cale’s loved ones, friends, and allies across multiple worlds are summoned to read his story (legend).

A watch the movie/series fanfiction that happens in the Spectacular Spider-Man world but also shows scenes from other versions of the characters. It might be less terrible than it sounds. Just... if you like Spider-Man, maybe give it a go.
(Yes, it's like a different fic of mine, just written differently and with more of a focus on the Midtown students. I like it better, if that means anything to you. No, the original version still exists; I haven't touched it.)
