... Is that just him, or is that pretty recent? Or recent-ish before Najaran boarded the train?

It's hard to tell what gives him that impression. The way her sentences were structured? Oh! Because she doesn't know the end of it? Or hasn't shared it, at least.

He pauses in his work, glancing at his young friend, before adding a soft "an' then what happened?" trying to get the full picture. He checks Goligan as well, just to see how the staff is faring-- while Najaran is more open on what she will say, Goligan has his share as well, and it was him who stopped Najaran when she was about to say too much. If he's prodding too far, he might get scolded for his nosiness.

... Well, it wouldn't be the first time, anyways.
