There's a half-proud, half-hopeful smile that crawls up one side of her mouth, pleased at first, but waning worriedly as she listens to Mettaton explain a little further about his cousin.

"Oh..." It sounds like even her best efforts at 'cheering up' won't be a one-time-fix-all, or even guaranteed to make Napstablook happier. Being a ghost is probably an emotionally complicated business.

"Napstablook's been sad for a long time?" It's the first time she's really ever heard about depression as a chronic problem, and Coraline is young and compassionate- she seems a little crestfallen for their sake, upset welling up in her eyes, though she bravely blinks it away and tries to take it all in maturely. Even so, the thought of not even being able to help a gloomy friend sometimes is heartbreakingly frustrating.

"But, but the music playing at the party, and at your concert too!" She protests, wondering how and when and why these rough patches came about. "It was so... peppy!"

She places her hand over Mettaton's metal fingers on her shoulder, looking up at him concernedly.

"Are they lonely, being invisible when they aren't paying attention to not being see-through? I could try to help them meet more friends? Friends who aren't scared of ghosts? I think-" She glanced down at the recorder, lowered against her side, conidering Napstablook's bigger needs. "That might be more important than wind."
