I think(hope!) she does. Otherwise, Frank will be dating(or married to!) a kid for the rest of his life(unless he becomes a god).

BTW, if she does, that means she was about fourteen, 'coz she was thirteen and it was September when she was resu'd and her birthday is in December.

P.S. If the year SoN/Moa and probably HoH along with Book Five happens in 2010, that means Nico is probably fifteen(I can hear the teenage girls who have a crush on him saying "Woohoo!" knowing he's about their age now and not too young for them. Not that they minded before).
