You were apart of the Metkayina clan A new family, the Sully family, had came there and started living there Anyways, you were just walking along the beach, since you needed fresh air for a bit Then... You saw one of the Sully children, Lo'ak, fighting with a few of the people from your clan. They all looked so much worse than lo'ak so far Then, the oldest Sully, Neteyam, came along and helped Lo'ak fight them Again, they looked so much worse than Neteyam and lo'ak You also saw one of the other Sullys, Kiri, watching from afar and giggling There's another Sully, but since she's young, she's probably back at her house with her parents, Jake and Neytiri
