Upon further reflection, I don't think Nori would get right back to being a weird pestering goblin after the final episode anymore. Think she'd try early on, but with everything that's weighing on her (almost twenty years of complete isolation, guilt and shame over misplaced blame for the core collapse and over ghosting her family, body horror, disgust and more shame from aforementioned body horror, losing Yeva and her family while she was gone) she'd almost immediately stop because she's not feeling it anymore, despite her unconvincing insistence that she's fine. Would spend a while being sad (or maybe "just" clingy with her family) and withdrawn outside her family and their associates. The other adult drones would feel slightly guilty over being relieved that Nori's too sad to resume bothering them with her autistic shenanigans.

>Lizzy's dad is horrified and practically shitting himself when he realizes Nori's in the vents and it's impossible to keep her out like he could before she was a headcrab... then she pokes out of the vent and sighs.
>"Hey Liam," she says, sounding distracted. Her eye isn't focused on anything in particular. "Wanna watch Lucky Star? I'm not in a good place right now."
