Tiny bonus I added as an afterthought when I first re-read the "chapter"
This is happening in the late evening, while Mathias is helping Emil clean up the dishes, and Lukas and Berwald are talking in the living room.
"I can't believe he ate that," complained Emil.
"I don't get it, why did you make it if you don't want him to like it ?"
"Brother said that I had to eat my vegetable because..."
He cleared his throat.
""The fact that you don't like it doesn't mean it's not good, or healthy"", he said, in a terrible imitation of his brother's voice, before going back to his own. "So I've been trying for a year to convince him he's wrong by cooking the foulest things I can find, and he keeps eating them !"
Mathias couldn't help it, he burst out laughing. Emil seemed so defeated and offended that Lukas ate what he thought was Emil's tentative of contribution to the house tasks.
