Where does ranofer get his plan from

In chapter four, Ranofer wakes, convinced that noises he heard in the night were the sounds of his father's spirit come to guide him. Ranofer gathers the small breakfast Gebu has left for him and visits his father's tomb, leaving half the meal as a gift. At Rekh's shop, Ranofer helps Heqet make solder for one of the craftsmen. As they work, Ranofer tells Heqet about Ibni, Gebu, and the stolen gold. Ranofer asks Heqet if he would tell Rekh the story, leaving out the part about Ranofer taking the wineskins to Gebu. Heqet quickly agrees, but they both decide it might be better to wait a few days until Ibni is able to fill a new wineskin with gold. That night Ranofer takes home the wineskin and is rewarded with money to buy himself some bread. Ranofer also overhears Gebu tell his friend that soon these wineskins will be insignificant to him.
