So I was just re-reading the book on the LABB murder cases, and near the end I noticed something rather unexpected. Here's the quote (pg 170): "If I had space left over I had intended to carry right on into the other two stories I heard from L: [including] the story of how [Watari] had first met L, then about eight years old - the case that gave birth to the century's greatest detective, the Winchester Mad Bombings that occurred just after the third world war." Your thoughts on that last bit?
Potentially a super underwhelming answer, but my friend and I used to joke around that Mello wrote LABB after blowing up the mafia hideout and was consequently high on narcotics at the time of penmanship because he was in terrible pain.
Initially, we were just kidding around, but the more time goes on, the more convinced I am that this is the only way to explain all the “wtf” in Another Note. I’m pretty sure WW3 never happened in the world of Death Note b/c it’s simply never referenced as an event that took place in recent history. Plus the whole DN universe is set up to resemble, I’d say, the real world at ~2000, with the assumption that 9/11 never happened (or would happen).
On a slightly more serious note, doesn’t Mello also claim that L prevented WW3 while he’s fanboying the man in the opening chapter or so? I may be misremembering that as it’s been a couple of years since I read AN myself, but I distinctly remember some offhand remark made about how all the people in the world owe L so much gratitude for preventing WW3 – though admittedly my memory is, again, fuzzy and this particular bit might come from the LCtW novel which we don’t talk about, lmao.
