Dedue may be faintly surprised when, of all people, it's Claude von Riegan who opens the door. He's definitely less surprised than Claude himself, whose mouth actually falls open as he stares for a moment. Not many people get the chance to thoroughly surprise Claude, so really, Dedue should enjoy this moment while it lasts.

But then he's breaking into a brilliant grin. "Dedue! Oh, man, I can't believe you're back! Goddess, I take back all those bad things I said about you." This last sentence is delivered towards the sky, before Claude reaches out to tug at Dedue's arm. This will be like tugging at a firmly anchored support beam unless Dedue cooperates with the pull, but Claude accompanies them with the magic words. "C'mon, Dimitri's going to be so happy to see you that I think he might pass out."

Claude's so excited on Dimitri's behalf that he's being a little overly familiar here, but Dedue probably won't care in the least if it means Claude is going to get him to Dimitri speedily. Claude's also said some puzzling things, but will Dedue bother to stop and ask about them before he's found Dimitri and settled himself comfortably into his position as vassal again? Quite possibly not.
