headcanon that when Kaeya was younger, he was hesitant to eat any food the Ragnvindr’s gave him for fear it was dangerous/had been tampered with. And when Crepus realized, he started taking a bite out of Kaeya’s food to show Kaeya it was safe everytime they ate
Young Diluc didn’t know why his dad did it, but he also started doing it as he figured whatever it was, it made Kaeya feel safer
this continued on subconsciously into their teen years. whenever they sat down to ate, Diluc would always take a bite of Kaeya’s food before Kaeya ate. People always just thought they were being typical brothers and that Diluc was stealing Kaeya’s food
then one day when their adults, Diluc does it subconsciously and everyone at the table (save for Kaeya) freezes
Everyone:
Diluc: what?
Amber: you just ate Sir Kaeya’s food??
Diluc:
Kaeya, who didn’t even realize till Amber brought it up:
Diluc: uh
