I went back to read the prologue and yeah what teach recalls isn’t what happened in the prologue, so someone is wrong here
If you go back to ch1, there's a different version of the events in that there seems to be vandals were there too. However, their bodies aren't shown in ch24 tho they could've reanimated and walked out. So someone's version of the events that led to his father's death is unreliable
NAH FR teach is an unreliable narrator to his own life and even a liar to himselfff this shit is crazy
Yeah and his dads body wasn’t there either, and from my interpretation, the vandal is depicted to be Guwon
My instinct tells me that Guwon didn't kill the father. Yes, he's crazy and doesn't understand what's wrong and what's right, but he ain't no lier like he said. Teach on the other hand, has an unreliable memory thing going on and he tried to kill Guwon in his sleep unknowingly. Most likely some trauma that's messing with his memory so with all the things Teach has heard about Guwon and with his memory being messed up, his brain conjured up a fake memory.
