Well minus a couple cases as the show went on, Meelo and Ikki tended to share a lot of opinions about how people looked at them and stuck together. Jinora was the brilliant one and the oldest, which would also inspire some jealousy in Ikki later if we decide to go that route. Lin being closer to the family and less reluctant to get to know them (hard, I know) may ease the transition from family friend to ...and I may be getting ahead of myself ...stepmother. :3
