Of course he eavesdropped on them, how could he not. And there's no trace of surprise on his face as he's informed of this truth, rather, he simply cheerfully chirps; "I'll have you know that I can have perfectly understandable conversations with the souvenirs I picked up when we were sent to Antwort." He did not understand a word of Raggs but that did not bother him in the least, never had, never would.

He stares a little while, once more going perfectly silent. Then he laughs a little awkwardly, rubbing the back of his head and grinning. "Ahahaha, today sure is a day of surprises~" He really doesn't know what to say but - and he does not show it - Yukikaze's words does make him think. "Yukikaze is being embarrassing today~☆"
