silly lute headcanons for the soul :)
How formal or casual she is with Adam depends on the situation, as well as her mood- she’ll be locked in her usual serious lieutenant mode in similarly serious situations, but when it’s public but not serious she’ll loosen up a little more and start acting slightly more casual with him, and in private settings (when she’s in a good mood) she’ll drop the formalities entirely and act almost as if their professional relationship doesn’t exist, a rare sight that Adam’s always grateful to see even if he doesn’t show it
She and Adam actually live together, and have been living together for a very long time- it started way back around the time they first met, when she was new in Heaven and didn’t really have a permanent place of residence, so he was just like “oh sure you can crash with me a few days, that’s fine” and then she just. Didn’t leave. (Not that he’s complaining though)
Likes spicy stuff. Like, really spicy stuff. She has an incredibly high tolerance for it, with spices having to measure like 2 million on the Scoville scale (for the record, that’s hotter than a Carolina Reaper) before she starts breaking even a little. For some reason, she seems to particularly enjoy casually drinking hot sauce out of the bottle- partly to intimidate people, partly out of a genuine love for the taste
Has Jessica Vosk’s impeccable pipes even in-universe, though only Adam ever really gets to hear her sing. He thinks she’s one of the greatest singers in all of Heaven (second only to him of course), wheras she insists that she’s only an amateur at best and is… kind of embarrassed by it
She and Adam preen each other’s wings! Well, usually she’s the one preening his wings, and then just does hers herself. Doesn’t want to waste her commander’s time, or give the impression that she needs help with it. Most of the time Adam insists that she let him preen them for her (since preening’s meant to be an intimate bonding activity and he is not passing up an opportunity to get intimate with her, even if it’s not intimate intimate) but she rarely does
Would never let anybody find out about this, but she likes touch. She loooves touching him, which is particularly noticeable when she’s in “casual roomie/best friend” mode and not lieutenant mode. It’s usually pretty small things, though, like just leaning next to him or wrapping an arm around him if she’s feeling particularly bold. This is why the preening is so important to her: she gets to both do a service to her beloved commander and quell her touch-starvation at the same time
I’ve talked about this before, but I’ll say it again: she actually has little tail feathers hidden under the uniform, black ones with white tips, which she goes out of her way to keep hidden no matter what she’s wearing, so only Adam knows about them. She’s embarrassed about them (though Adam insists that they’re cute, which just embarrasses her even more)
Also has black nails under the gloves! She likes the bird of prey aura they give her, she thinks they’re badass (same reason why she perches like a gargoyle)
