Props to MC for at least thinking about all the stuff that doesn't add up here regarding Little Girl's Age. And I actually like that he hasn't immediately arrived at the obviously correct answer of "She's a Vampire". That combination helps the mystery actually feel like a mystery while not making him feel like a Dumbass.
That said I'm disappointed that the massive hoard of Magic Items is just in a pile on the ground and not organized like Hanger 51 like damn bitch you live like this? Oh well, at least she's apparently trying to tidy up a bit.
