God i might be dumb but i think i'm missing chunks of plot here. Thing either didnt get properly addressed or the reasoning is too hard for me to comprehend
On the off chance you’re talking about the (seemingly) random letter in chapter 12–It’s a letter FROM Callahan TO Johnny’s mother. He had bought into Johnny’s story and wanted to reassure Johnny’s mother that he was still alive after all this while, but the letter he had sent had come back to him because she was no longer around. Either that, or it was never sent in the first place because he realised Johnny wasn’t so truthful
Man I really suggest lots if you to just go back and reread the last chapters because why is there many comments saying leo did the same to JJ or he is just as horrible. I think yall mistaken your head canon with what happen in canon
To remind you all all leo did wrong is he took jj love for granted. And part of the reason why leo did that is because jj never communicated his issue to leo. How can a sane mind say thay is equal mistake as sexually assaulting someone
