Did Ezinma actually bury the pebble or is it just a coincidence that it was found?

Ezinma's pebble is her iyi-uwa. This smooth pebble is wrapped in a rag and buried to signify a bond with the world of the ogbanje. It was originally buried so that it could be dug up later and destroyed. After leading the villagers on a chase around the village (thanks to the medicine man) she pointed out the pebble's location to Okagbue and Okonkwo, who dug it up. It’s not a coincidence.
