[Kariya is used to Byakuya's constant state of jitters -- it's what he remembers from his childhood years, the strange sense that his brother was always on the edge of flight and wondering when he would disappear.

... He thinks it's more ironic that they're both named after birds, when watching the creatures always gave him that same unsettled feeling.

So the sudden stillness jolts him further into wakefulness more than anything else, but he doesn't get more than a vaguely concerned glimpse of Byakuya's face before he looks away in a hurry. He feels like he saw something he wasn't at all meant to see -- something he said, off-hand, shouldn't--

He feels oddly guilty even amid the confusion. He doesn't take it back.]
