My friend, who was a huge TBP fan YEARS before me and spent forever convincing me to read the trilogy, never read Death's End
So my friend is an awesome guy, but holy shit. We were chatting about the TBP TV show not long ago and he mentioned that he "didn't like the fact that characters from the book got split into multiple characters in the show" and that the show "focuses too much on romance." I was confused so I tried to explain that the characters were pretty 1:1 from the book to the show, the only difference being that we see characters from all three books at the same time. This made him even more confused than I was so I drew some parallels, mentioning Wade and Cheng Xin. And bro goes; "Who are those guys." And I'm like "ummm Cheng Xin becomes the Sword Holder and Wade is the guy who shoots her? You don't remember that?" and he's like "No, I don't." So I say "You read the trilogy right?" and he's like "Yeah" and I say "tell me the last thing that happened at the end of the trilogy?" and bro goes "Luo Ji stops Trisolaris from invading Earth by revealing the Dark Forest deterrence." I was completely floored. This whole time I thought I was catching up on a series that he is an expert in, only to find that he's been LARPING this entire time W/O EVEN KNOWING IT. So after telling him that there is in fact a third book and that it is extremely good he agrees to read it. But the cherry on top of this whole interaction is after he agrees to read it he says "I mean the ending of Dark Forest was perfect, what else could happen?" Oh buddy, you have no idea...
