Mettaton's eyes are soft as Napstablook talks, going on and on about the poster and the best colors to match it. It's been too long since it was safe enough for them to hang out and just be. This is another notch in that time frame however. He has a job to do. So he'll do it.

His hands deftly and surreptitiously bring up another piece of paper to the table and adds it to the current pile that will go with this particular fan. It looks like a simple roster of tour dates; but with the right set of code breakers, it will reveal itself as coordinates and security schedules for some of Genosha's most heavily guarded government buildings.

Then his cousin asks for a hug and he knows exactly what his bodyguards will say if he lets them speak. We're sorry, but Mettaton isn't available for such things as this time. We hope you understand. So he doesn't let them. He's already standing before Napstablook can finish their sentence and before his people can put a hand on his shoulder to stop him.

"Of course! Anything for such a devoted fan!"

He wraps them in a tight hug, knowing that it can't last, but thankful that he can slip it in anyway.
