Heartwarming / Kingsglaive: Final Fantasy XV

• When Nyx gets reassigned to gatekeeping duty in the film's opening, he gets mocked by another gatekeeper for being an immigrant and "playing war hero". At the film's climax, that very same gatekeeper shows up to help Nyx and Luna escape Insomnia.
• Libertus' first instinct after figuring out that some of the glaives have betrayed Lucis and are now working with the empire is to go and try to save Nyx, who he recently had a public falling out with. It just shows how close these two had become during their time in the Kingsglaive.
  • Even when faced with the fact that Nyx probably won't be getting out of Insomnia alive, Libertus still insists that they'll eventually meet each other back in their home in Galahd.
  • He even extends his invitation to Luna and Noct.
• When Luna discovers that Regis tried arranging for a Glaive to meet her and smuggle her out of Tenebrae, her first reaction is to try and find that Glaive so she can thank her. When she finds out Crowe's died, she decides to keep the hairpin Crowe was going to give her in her memory.
• Luna and Nyx's quiet, intimate conversation before the final act, where he shares with her the death of his sister, and opens up about his feelings of helplessness. Luna offers gentle words of comfort and care to him, understanding all too well how he feels.
• The various Ship Tease moments and exchanges between Luna and Nyx from the moment they first meet, their evident growing chemistry and mutual respect and how they become steadily closer over the course of the movie, saving, trusting, comforting, encouraging and depending on one another, opening up, and making an impressive team against Niflheim, despite only knowing one another for two days tops. With many fans arguing she ended up having more natural chemistry and screen time with Nyx than she did in the actual game with Noctis. Along with her final saddened parting promise to save the future for him, vowing to keep that promise, while he performs a Heroic Sacrifice to save her life, with her even waiting for him sadly at the end and him not returning, the entire thing coming off like a tragic, doomed romance. It is little wonder many ship them, whether the writers intended it or not.
• Initially, the Lucian Kings just mock Nyx, since he doesn't have royal blood. Then King Regis speaks up from among them, insisting that Nyx seeks to safeguard the future, convincing the others to give Nyx a chance.
