[It's a good job Nobuchika doesn't touch the instrument, really. Mitsuhide's grip on it grows a little tighter, and protective, as Nobuchika looks upon it. The samurai doesn't want to seem so obviously on edge, but his expression, as always, gives his feelings away.]

[He closes his eyes and shakes his head. This isn't the time or place to touch upon that subject, and he has no desire to do so with someone he just met. Even if they are the son of another version of Motochika.]

[Instead he focuses on what the other man says next.]

Gyarados? Is that... is that the dragon?

[Mitsuhide's gaze settle on said creature, though his eyes look a little distant as he does so. There are clearly other things on his mind. After a moment he says, in a quiet and slightly pained voice:]

Lord Motochika is attuned to the water, and especially the ocean. The image of a water dragon is fitting for his instrument.
