I'm starting to wonder, are the three blonde nuns somehow related? It seems to be the older one tends to be pretty bias/good relationship to the main girl, as well as they seem to have the same color eyes. Makes me wonder a bit.
Of course, I doubt she is her mother or anything like that(since nuns) but perhaps like a cousin or actual sister? We also don't see the original strict nun anymore that took care of the older one and freckles, plus the others one.
Wonder what happened. So many questions, so much mystery. What is the lore to the world of these little nuns? What kind of world do they live in?
*Edit: Quick fun trivia, it seems that certain nuns CAN technically get married, or that a married women could become a nun, although there might some difficulty(i.e having to leave their spouse or something). I'm assuming they also might be able to have kids too, but that seems to be pretty iffy.
Although I guess it depends on the specific types of religion they're in. We don't really know if the nuns here are actual Catholics due to...well, not knowing if their world is the same as the real world or in fact an alternate or fantasy world nor which type of Catholic they are, or how strict their swore of oaths are. We also don't know, even though they have crosses, if it is the same meaning or if they have their own Jesus or a different messiah altogether.
