Percy Jackson/Heroes of Olympus headcanons

𝓝𝓲𝓬𝓸 𝓪𝓷𝓭 𝓗𝓪𝔃𝓮𝓵💀💎

- They are really protective of each other. You say something mean to Hazel, get a taste of the ghost king(I am not saying that hazel needs a guy. she is a freaking queen). You insult Nico? You might as well be dead cause of a certain praetor Levesque

- They start spending more time together ,to get to know each other as brother and sister

- it gets to the point where Frank and Nico argue for hazel(they end up making a deal that Hazel agrees with)

- Hades gives them both midnight black horses and gifts, Nico finds out he actually likes horse riding

- Sparring together

- The number of inside jokes is like, unbelievable. You say something random and they will just look at each other and they will start laughing uncontrollably.
