It’s the most obvious explanation, but I don’t think anyone expects that of Luna on a base level.
@PlotHole
Or maybe Luna in the past used to be busy
Adopted niece is a thing that can happen (I have one), but it implies a sibling’s adopted daughter (in my case) or an adopted sibling’s daughter, which is why Luna is giving Celly that look. And at least in my case, I never mention the adopted part, or that technically she’s my half niece, because her adoptive father is my half-brother (our family tree is a bush :-).
It’s likely an honorary title, much like Blueblood has ‘nephew’.
Maybe it’s another Celestia quirk where she’d feel old if she called her “adopted daughter” same as with calling herself “Princess”
