That's me exactly as well! I'm replaying Inquisition really slowly right now just for Varric and it's just not as good, damn it.

We can totally handwave and keep it for the game! Varric's pretty uneasy and freaked out himself and he's not going to notice Nina being uneasy for anything other than the same reason as him. He'll be happy to talk about whatever to keep her - and him! - sane for as long as she needs.
