Nona and Davrin asks be upon ye! Can I have 3, 7, and 8 please Mouse?
Hellooooo, you most definitely can!!!
3. How long does it take for them to officially get together? Did any of the other Lighthouse members have any suspicions beforehand?
OOOOH. It takes them a little while! Nona and Davrin do initiate a physical relationship before they formally get together, and there's plenty of flirting in-between-- Nona wants to be professional, she really does, but there's just something about Davrin, you know? But they tell themselves and each other that there's no strings, just blowing off steam, friends supporting each other. And then Weisshaupt happens. And everything changes. Their physical relationship actually stops for a time as they figure out this new dynamic, and start to approach each other with a very new point of view. SO. They don't formally get together as a proper couple until after Weisshaupt, and even then, it takes a bit of time.
7. Are they a physically affectionate couple? Are they fine displaying those affections in public or do they prefer to be in private? If they're not, how do they prefer to show their love instead?
8. What does their ideal date look like? Do they go on much?
A walk in the woods!! They pack up a picnic, wander off into Arlathan or the jungles around Rivain or even the pseudo-forests of the Fade, and walk for a while before settling in to eat and talk. If the setting is right, they don't pack -- they hunt and forage and make a campfire to cook what they've caught, and just talk for a while. Sometimes they camp out overnight, but not often, not while the Veilguard is needed.
