Byakuya ticked up an eyebrow. He understood not wanting to talk about it, but he wasn't going to allow Xavier that much of an easy out. He wanted answers, but the tea reminded him that Unohana was, no doubt, hovering near by (even if she was completely across the island, that was "near by") and she would not take kindly to her patient being stressed.

"The accusations against you are serious. A lapse in memory will do nothing to stave off the repercussions." Slightly scolding, but nothing more. He wanted Xavier to talk.
