On An Island with Consequences Dire - Part 6

On the island, Georgia meets Boo Te Pa again. He asks her what she 'and the other girl' did with Bridey girl. This is not good news as it confirms that Boo knows their secret. Meanwhile Kate, who has been digging a dam on the farm, has unearthed two skeletons but reburies them so the dam will not be delayed. Could this be connected to her mother's disappearance?
