I loved relationship between Avatar Roku and Monk Gyatso. Having grown up and trained together, then Roku moving on and later dying. Gyatso must have been devastated at the loss of his friend but, hopeful knowing he would come back as and Air Nomad. Then Gyatso as the guardian of Aang and teaching and hanging out with Aang (Roku) again. Then blatantly defying the monks' orders to separate from Aang. He just wanted to be with his friend. Then Aang finds his body in the cave, cycle of pain again.
oh my god… just… wow ;_;
