At the admission that this robot apparently doesn't know who Porky even is, Lucas visibly relaxes considerably--as if that had been the biggest worry of them all, in this entire situation. (Which would be about right.) But there's not a lot of time to react, otherwise, because then the robot's diving right into an explanation on pop idols that leaves Lucas feeling...rather as if he now knows even less than he did to begin with.

Looking very faintly overwhelmed but not entirely put off (though maybe just a bit abashed--'beautiful'.......?), Lucas slowly begins making his way around the counter now, staring at Mettaton with increasing curiosity. "That's--a lot of things at once. A pop idol sounds...very time consuming." What's a choreographer, for that matter? Maybe he ought not ask. But the mention of cooking earns a small tilt of his head. "Oh...but is that why you came here? To cook?"
