Dedue does, regardless of what Felix might think, understand that there are times when he is best utilized away from Dimitri's side-- he has, after all, fought on the battlefield some distance away from His Highness. Felix is right, though, to think that Dedue will not allow anyone to slam the door in his face and try to cut him out of Dimitri's life because they aren't comfortable with the concept of change.

Felix.

"I did not think that you hated him," he says. "If you hated him, you would not have watched over him as you did."

There had almost been an unspoken schedule between them-- when Felix was not watching over Dimitri as he skulked about the ruined cathedral, Dedue was there, and when Dedue had other duties around the monastery, Felix took up the post. Both of them, orbiting Dimitri like moons.

"Your behavior is strange, though," he concedes. "You have yet to insult him. I can only assume that you have found some way to reconcile with His Highness."

Some of the pictures scattered about the room would suggest as much, as well-- there's one or two of them that have Felix and Dimitri in them, the two of them interacting in friendly circumstances. Touching, even, and not during a spar at that. It's something that could have never happened without somehow mending their friendship, as unbelievable as such a thing sounds.
