After Wolf had originally returned from Edward's Flying Eagle tribe, he had quickly acted to secure his position and finally getting rid of his worries.
He had become the leader of the Cloud tribe through the deer that was given to him by Edward as compensation. At the same time, he learned from the injured Titan about the bow and arrow Edward had made, on his way back to the Cloud tribe.
This secret had immediately helped him land in the position of the leader of the Cloud tribe along with the deer he brought back.
But there is no impenetrable wall. His original competitor, Leopard, did not know from where Wolf had learned all this. Leopard was going strong head to head against Wolf and everyone in the tribe assumed it would be a close call.
