Shisui was often strained and stressed; he just did a good job of not showing it.

He was glad to see her. He wasn't exactly going to go out on a limb and say he missed her, but it came close. With Itachi away, she was probably the only other person he could sit down and enjoy conversation with. Of course, there was Sasuke; but the two of them haven't really had one long uninterrupted conversation in years.

Shisui almost laughed at her attempt to restrain that smile, though, knowing full well what was going through her head. "Sure it is. If it wasn't long and tiring, I'd be eyeing you suspiciously. I trust it went smoothly, regardless? And-- you've provided a 'detailed' report, yes?" His eyes twinkled at 'detailed report', the smile widening. "You better have, because I have something neat to show you today. Wouldn't want you detained for interrogation."
