Where No Whale Swims - S2.E2

Neri makes her first visit to ORCA since her return, and tells her friends that she wants to discover who ""her people"" were. Jason, Brett and Neri go to her island to look for clues to her identity. Brett gives Neri the pendant he found in the flower, and Neri tells him it was her fathers and is a map of the island. Following clues found on the island, a large object is discovered under the island–from what they have learned so far, Jason suspects it to be a spacecraft. Mick locks Rocky in the recompression chamber.
