Only somewhat of note, I imagine blue-purple cyborgs are not the norm in Solvunn, so by that note alone her kind of sort of busybodiness was probably noticed in some form. As she hates idle hands, Nebula has been seen to keep very busy and assist in all kinds of matters around the Settlements (Primary, mainly). These include:

(Carnivale, so doesn't super count) She was present in Ikorr and while she did not vote one way or another did spend time learning about the locale and trying to help keep people from getting in various trouble. (TL
- Her first days included standing confused guard and threatening Eli the goat . Also an absurd amount of fishing, like someone stop her. For Himeka, but she'd have given extra away.(1)
- Helped Wanda (1) look after kids and teach them how to make colored eggs... No, she still doesn't get it.
- During the upheavel in Solvunn helped guide back lost children with Rocket while an animal pursued them in the woods; Sometimes you make kids cry accidentally while trying to do the right thing.
- When trapped by bad weather, helped Eddie watch over some kids and critiqued his story skills.
- Seen helping gather and chop downed trees/wood with Wanda
- By the end of event 18, it's become normal to see Nebula around the commune helping repair buildings and do heavy labor. As seen when Himeka finds her here (it's an entire TL).
- Her disdain of goats became more evident should anyone pass her by during the goat races where she'd tell them to go away... Also while helping keep an eye on them when their people walked away. She's very contradictory.
- As a new member of the Treehouse has become involved in the Welcoming committee alongside Himeka, Wanda, and Rocket. Begrudgingly or not she is trying to be more helpful (friendly)?
- She did join Aloy's hunting group after weeks of staying in the woods scaring off/taking care of threats even before her adventure with Rocket! While definitely a thing, short of a TL prompt not much has been done here yet.

I can try and find direct links but while the above gets the jist of it: Nebula comes across as a serious, no-nonsense hardworker. While she doesn't stand around for small talk and can come across as ornery, if it comes to someone's home needing upkeep or help procuring food she usually takes the time to help. Especially/during after the bad weather, Nebula made a concentrated effort to invest a lot of time in clearing up areas and repairing what needed to be done. She didn't often help look for lost goats - yes, it's personal - if some kid looked at her sadly she definitely did! And most notably, she kept an eye out and was softer with children than adults.
