There might be some sense to your knocking if we had a door between us

Jiro attempts to remain in a good mood. For the sake of his brother. The tension rolling off of their father is palpable and he understands it. If he were Hattori, he would feel similarly. Jaded. In a sense, Jiro did feel jaded too. Kiriko had been a lackluster mother for as much as he had tried to spend time with her, and now that she'd run off, it was almost as if he questioned why she had even stayed to begin with. Why even have them if she didn't want to mother them? Frustration that he had done so well to hide bubbles up, but is quick to push it back down as Keito confirms that he has found nothing.

Instead, Jiro tries to focus on the good. "We've missed you too!" He says, his voice dampened with the heavy aura of dismay, but still attempting to be light and cheerful. When their father speaks, Jiro's ears turn backward, eyes sliding over to look disappointedly in Hattori's direction. Could he not spare one moment of joy for his son who had returned?
