I'm sure whatever Josephine says to the Qunari will be simple, most likely, "Shanedan." It's respectful and pretty universal for any Qunari I would imagine. Regardless, I'm eager for the interaction because it's more of a testament to Josephine's considerate and diplomatic nature.
Not to mention it's pretty damn endearing to. 
As far as I've seen a lot of people really appreciated and liked that part of the stream.
I can't wait to see what other conversation topics we can have while speaking with her. The obvious things are probably about Antiva and her line of work. Anyone else have any ideas? I know they said something about our origin story being revealed throughout the game, rather than front-loaded. Think some of it will be revealed in conversations with our advisors and companions?
To be honest, talking with companions is one of my favorite things to do in BioWare games. Befriending them further cements my investment in the story.
