[Ha... there's a... soft sort of warm, thrumming low note in Mettaton's tone when he first patches in? Just like... not a mirthful one, no, but a conversational, confident "laugh".]

Mettaton, television host and superstar -- it is an absolute pleasure to make your acquaintance, dear Zelda!

As for the question!

[He swings a point into the air in a flourish!]

Well... [His -- smile drops for just a second. As if in a doubting, silent "hm?" But...! Back on, it is - eyebrows lifting...!] I did say "superstar", did I not?

[That warm note risin' higher with his tonal projection.]

I'm here on a detour off a thriving career! Away from legions and legions of adoring fans! It's a dull, dull world without a bit of MTT-brand glitz and charisma!! Why, you could say my planet NEEDS me!!

[A... little wistful slant to one o' those eyebrows.]

But...

[That look warming back over. Right along with his tone - starting lowwwww.]

Ooooooooh, that doesn't mean that I'll be stingy about sharing the same... spark with the people of this planet, now, does it?

[With a little shake of his head and light, slow brush of his bangs.

And, I mean... only you know the answer to that, friend.

Aaaand it's obvious the answer is "no".]
