#crepus

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 would probably bring birds into the house when he wasn’t setting the drapes on fire.

Diluc would run inside and show crepus business partners the snake in the garden he got

Diluc lit half the grape fields on fire because he wanted to make snores.

Diluc would leave a trial of destruction in his wake. While Kaeya had the talent of magically going to any place in the world as soon as you blink

Crepus leaves the door open to get fresh air? Kaeya has now walked to a hillicurl camp and made friends with all of them

Crepus busy trying to get diluc to not release frogs into the house?Kaeya is now on top of the knight headquarters because he wanted a calm place to read

"Oh, Crepus's death must have affected Kaeya just like it affected Diluc!"

like...

Imagine Kaeya going to Varka for advice and Varka being his usual charismatic self. Probably teasing Kaeya that if he’s a real knight, he should be skilled with blades no matter if it’s swords or the razors of a shaver. Maybe after Kaeya got the hang of it, Varka would reminisce how particular Crepus was his shaving routine, how he would only use a high quality razor from Fontaine to clean up his sides.

Then cut to Diluc, still a long ways from Mondstadt on his own with no one to turn to, trying to figure it out. He probably started growing stubble along his chin and began finding it annoying and itchy as all hell. With trying to lay low, he attempted to shave it with a pocket knife only to nick himself in the process. It was only after he returned home that he actually learned how to maintain it by Elzer or even Adelinde.
