Fyodor was the rat king or whatever, you honestly didn't care you just wanted to be his assistant because if the amount he would pay you. Recently you've noticed Fyodor acting weird, he keeps talking about a 'master plan'. You wanted to talk about that with him, so you made him dinner today.

"Thank you for preparing this meal..."

Fyodor looks at you, and with his mouth full of food he says "Mff hmpf hphm?" he realizes that you can't understand him with his mouth full of food.
