"Dimitri has been doing well here. His moods are more stable, he is not so prone to fits of ill temper. He has found happiness and enjoyment in activities that he would have never before allowed himself to consider."

This may seem like a bit of a non-sequitur, but it is a relevant thing, as Dimitri's happiness so often is to Dedue's actions.

"Were I to speak to him of these pains that I have..." he shakes his head, as though dismissing the very notion of it. "He would believe himself responsible for it. I will not be the whip by which he flagellates himself."
