[As much as Reira herself could put feeling to the word-specifically Napstablook's own-she's not familiar with most feelings in general to actually put a word to the feeling aloud...so she just sort of listens, tilting her head for a moment.

She won't press at least. She might not be the most tactful when it comes to people that would rather not be around but she can at least figure out where it's best not to pry much more.] Umnh....Napstablook? [She'd note that she knows of ghost monsters that have ghost in the name but.... ............she has a feeling saying anything contrary to Napstablook's words would make him feel quite a lot worse.]

Ok-!

...I'm Reira-umh...welcome to the Carnival, then..! [she adds, the welcome awkward, but at the very least not forced.] ...It's supposed to be fun, even though I don't know why.

[She calls it like she sees it!]
