After a quick glance around just to make sure it isn't Squalo throwing his voice to troll him, the Cat's response is met with a bright smile. Vindication.

"I knew you could talk." But he isn't smug about it, just pleased that this means it'll be easier communicating going forward. Hopefully. And he doesn't neglect his play duties, yanking the bottlecap out of the Cat's reach at the last moment and sending it plink-plink-plinking in the opposite direction. "What should I call you, then?"
