Oh hey, look at who it is! Mettaton listens to Papyrus, of course, but his eye also looks to be inspecting. Well well. Not a bad-looking specimen!! Oh, but anyway. He's not going to flirt with a candy bar in one hand and a pack of fish in the other.

"Are you now?" he hums, setting the package he was holding back on the shelf. "Wonderful then!! It just means I won't be needing to cook tonight, I could use the break~ But enough about that, it's wonderful to meet you in person, sweetheart! And a little more in-the-flesh than I remember Undyne's protege being!"

Still. The bone structure's there, though he doesn't say it for fear of sounding unnecessarily punny.

In addition, Papyrus' Pokémon were sufficiently distracting, because look at these precious fuzzballs!

"Aww, honey! You have the most darling babies!!" he exclaims, stooping down so as to offer the catlike creatures free pets.
