What a strange set of questions. How are they supposed to know?

" Iqg zir' azh. Qu quizh uzheqg fi alz. Eqh nireqh fi nirus alzilz. Zir' riruzh."
"Oh, um, they said they don't know, probably a year? And they said everyone should just leave! Um, and not linger?"

It's clear that Fen didn't match their tone at all. They didn't get all excited or question their statement but Fen sure did.
