Nia is fond of Montréal and they seem to like her too, so she's studying French and has collected a stack of library books to do it with and staked out an unclaimed carrel in the section that appears to be devoted to books about the Cote d'Ivoire, which speaks French. However, she doesn't want to overstay her welcome; better to keep an eye on Montréal from a polite distance, bounce in when they want help, accumulate favors owed, make sure no one dreads her approach, and have them to turn to when she really needs something. Besides, one does not want to have all one's eggs in one basket, when one lives in a school full of basket-rupturing monsters who love eating eggs. Montréal is a great prospect! But she should have more friends and now is when to make them, when she's gotten all her Friday homework done acceptably and done her maintenance shift of clearing away some broken chairs in a classroom and replacing them with more chairs from a chair supply cupboard. (She got to keep the broken chairs and is not sure what she'll do with them but wood is wood.)
So, after a hop (literally, on one foot, it's good for mana) through the Cote d'Ivoire section to see what's there, she ventures into the more densely populated areas of the library to meet more people.
