...Well. Alright. The robot's made no move to attack just yet, so that's a very good sign already--in Lucas's experience, most robots that plan on attacking at all don't really waste any time doing it. The open-handed gesture is a nice touch too--this guy certainly does seem weapon-free...

Lucas relaxes marginally but visibly, at the words. Hesitates, and then draws forward just enough to set his squash platter safely onto the counter--though he still keeps said counter between the both of them. Mostly just to be on the safe side, but also...because he now has quite a few questions, if the way his expression closes with some faint confusion is anything to go by.

"...I'm Lucas." He pauses, rubbing one of his arms and eyeing Mettaton uncertainly. "What's...a 'pop idol'? --You're not one of Porky's robots, are you?"
