Mukuro listened quietly, eyes focused dully on the now younger yakuza, trying to reconcile this new (or was it old?) version of him with the one she remembered. Although she was vaguely interested in the new world she'd been dumped into, she only had so much capacity for emotion left, and at the moment she was using most of it to wonder vaguely about what the hell had happened to him. 'New World Program' was unfamiliar to her, but it sounded appropriately grand and interesting to be filed away for later.

Different times, different worlds... she shook her head slightly, not in disagreement but rather in disbelief. It had to be true, of course, how else could this Kuzuryuu even exist? But it wasn't something she'd ever bothered thinking about before, and being faced with it now... She straightened a bit at the mention of Peko, eyebrows rising-- until she realized the implication he was making. She wasn't around any more.

"I'm sorry," she said, automatically, and realized half a second later that she should probably not even know who Peko is, let alone the fact that they were close. God. She'd never been good at being undercover.
