The Big Clue You Probably Missed Early On In No Time To Die
As pointed out by TikTok user @hiddenmoviedetails, early on in "No Time to Die," James Bond visits his "Casino Royale" love interest Vesper Lynd's (Eva Green) tomb to try to finally make peace with her death. Written on her tomb is an inscription in Latin that reads, "What you are, I once was. What I am, you will become." The scene comes and goes fairly quickly and is rather meaningless to those who can't understand Latin, but it certainly seems to be foreshadowing Bond's death later on in the film.
It's somewhat appropriate that this clue into Bond's fate would come from Lynd's tomb since her death in "Casino Royale" served as a kind of catalyst for Bond's character arc throughout Craig's time portraying him. In fact, it's the major event that tied most of his films together as he hunted down the organization responsible for forcing her to work for them (resulting in her death). Whether her tomb's inscription is intentional foreshadowing on the part of the filmmakers is impossible to say for sure, but it would add yet another layer of emotional complexity to Craig's time as the legendary character.
