Nico slowly realizing that his cheeks heat up most of the time whenever he sees Jason or when he’s just hanging out with his best friend and he’s so confused why is that so. Until Percy tells him while wiggling his eyebrows, “That’s called blushing and I can sense someone crushing on a certain son of Zeus.”
Percy expects Nico to deny and maybe punch him but no, Nico just blushes even more because “Oh gods. You’re right.” And Nico panics. “What do I do, Percy?”
“You go tell him and kiss him like a man!”
Nico’s stands up and shakes himself. “You’re right! I should just tell him and—” he looks back at Percy and blushes even more upon realizing what Percy just said “WHAT IN HADES—I can’t just do...that!” Nico was clearly scandalized.
Then from afar, Jason sees them and smiles because his two friends are getting along better than he expected after everything that happened.
