You never knew Fyodor as a kind person, if anything he was a harsh one. Disregarding other's feelings whenever he spoke — saying that he was only telling the truth. I suppose the truth hurts a lot of the time, doesn't it?
You had felt yourself becoming less valuable to the Decay of the Angels — your mental health deteriorating everyday, causing you to fall back into old habits.
And Fyodor — as always — took notice of this. At first, he simply ignored it, not caring about a blatant waste of time such as your mental state.
At least until it started to affect the small organisation as a whole.
Your work performance soon came to a halt, you hardly did anything that was asked of you. This annoyed Fyodor — annoyed as his plan was failing due to your poor work ethic.
By this point, he had had enough of this nonsense, going to where you lived to make you start working again. As he walked inside, he took note of the disgraceful state your home was left in due to your problems.
"You're useless,"
He spat out, there was no character in his voice. It only stayed monotone.
"Less than useless, you're sick."
