[Don't worry Jaskier, all Sebastian wants to do is fill out forms and keep the books. He has a passion for paperwork. All the better, because Kazuki definitely doesn't.]

Oh-- Hi, Zuke! Wow, the gang's all here! [Kazuki is a the-more-the-merrier type, Jaskier could have come in with a whole troupe and he'd still be down for it.] It's great to see you guys again!

Yeah, jam is the right word! What'd'you got in there? [He turns his head curiously at the bag, it's not a shape he recognizes.] If you all want, I've got a soundproof room with a piano down the hall. We could check it out there!

[Just because he's running an inn doesn't mean he can't be a musician too! He teaches local kids out of that room. It's kind of his favorite place.]
