Sounds like a plan! Let's say they just talk about the Fold and a few creepy DA2 things (she'd be interested in apostates), and he could probably pick up she's got some weird magic background as well and then it was probably like: OK, let's get some sleep while we can. I'd say we could imagine some basic worldbuilding stuff got shared too, and just play it by ear when they're talking in game for if we wanna be like: oh, this is new or oh, I heard some of this, tell more?
