If Yuuhi noticed anything odd about the way things were phrased, he didn't mention it. Syaoran had brought it up before that her brother and Yuki were close friends. It didn't strike him to pry any further than that. He just nodded amiably and wondered if that would still be the case if Yue and Yukito got another chance to speak with Touya about breakfast this morning.

Sakura was another matter though. His own princess hadn't been around for more than a day and night before she vanished, but he understood all too well what the signs were and what they might mean. Yuuhi's smile faded momentarily. If the doctor was keeping his Sakura hostage, who was to say he wouldn't do the same with the other? Or worse, if he couldn't experiment on one, perhaps-

He wanted to offer to help. Go visit her, check in... even if nothing could be done when and if they finally took her, at least they'd know they tried. But he'd told Yue he wouldn't get in their way anymore. He didn't need the doctor using any more of the people who were important to him as bait.

"Then I guess we ought to hurry and get to the bottom of things," he tried. There was little chance they would be able to free themselves and everyone here before the girl vanished or they themselves disappeared, but maybe it would give them some direction.

"I wish I could offer you better advice, but- I'll let you know if I find anything out." Another lie, but at least a well-intentioned one.
