To which part are you referring? We may be able to help you (or find the plot holes)
Unless it has anything to do with the feral Callahan chapter.
The fact that this part was actually explained with the weirdest ass explanation was gold though
What was the explanation?
He got saved by monkeys who were starving and he helped them by showing them how to steal cattle from farms - though you could say that we don't get a clear explanation for his state of mind or how in the hell he could understand those monkeys in the first place (￣∇￣")
Ah, thank you for the reminder. It has been a while and I probably skipped those chapters in the official version (so I could keep reading haha).
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
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
