So this is a slightly different Dedue than the one who was here before - one who's come from a different point in time. Though again, unlike everyone else, with Dedue it hardly matters; nothing ever changes with him. He'll always just blindly follow Dimitri around and never question anything he does, whether awful or self-destructive or both, until one or the other of them dies. Sickening.

"Hmph. So you remember all the same things Dimitri does." Dimitri, not the boar. "The rest of us have come from later points in time." Felix's scowl deepens. "You haven't even seen how Gronder ends, when he was at his worst, and yet you still intend to do whatever he tells you to do, no matter how cruel it may be to himself or to others. You care about him so little as a person that you'll allow him to think the worst of himself, to be his worst self, without lifting a finger to actually help him."

...Felix didn't mean to start any of this. He never meant to talk to Dedue at all, but here they are anyway.

"Tch. Never mind. You never listen."
