Destiny 2 is one of those games where players can really notice how much attention to detail there is, with Bungie crafting every little aspect of the experience with great care. This includes cinematics, with all the audio and video departments combined to create something truly unique, but even the base game is full of those moments where it all fits together. Those who played the game at launch will know how this feeling was always present during Destiny 2's Red War, from the very beginning of it all, when the Guardians were forced to leave the City, Without Light.
This continued in Forsaken, of course, with a wonderful soundtrack that blended perfectly with the narrative and characters. A striking example is the movie with Cayde-6's last battle against the Scorn in the Prison of Elders, moments before his Ghost is killed by Pirrha, one of the Despised Barons. That cinematic is the pinnacle of detail in Destiny 2, even including sounds like Ace of Spades reloading and gaining Memento Mori, or Golden Gun Super as soon as Cayde uses it. However, a Reddit user by the name of warlockShaxx reported how Bungie missed something big, or perhaps paid the notorious Cayde-6 a terrible tribute in that very movie. In fact, Cayde is seen hitting many Scorn enemies and he is known to be an excellent gunman who never misses a shot and yet the trailer never shows Firefly blasts of precision kills.
As such, warlockShaxx claims that it's possible canonically speaking Cayde never got a headshot, or maybe Firefly was for some reason absent from the Caydes version of the Ace of Spades. Another Redditor named asylumprophet was quick to respond to warlockShaxx's post saying that this happens because Cayde was voiced by Nathan Fillion, and his sci-fi series Firefly was canceled. The joke is brilliant and ties in perfectly with the original post, so much so that asylumprophet got more upvotes than the actual post, and lots of awards too.
While many Destiny 2 players are still upset over Caydes' death in Forsaken, it may have been a blessing in disguise due to the number of important story moments he created. Regardless, the reason why Caydes shots never cause solar flares through Firefly remains a mystery, and with Forsaken being vaulted soon, Bungie will likely never share the answer to this.
