After Adam returned, flanked by Ash and his friends, with his latest find, Evelyn revealed that the necklace was actually made of less valuable Green Shards and not emeralds. This disappointed Adam for a moment, but he then deduced that the shards were from the King Neptune, a sunken ship. Evelyn suggested the Relicanth could lead them to the King Neptune, and so the group set out to find the sunken ship in Adam's submarine.
Evelyn drove the group out to the middle of the ocean in a large boat, so that Adam and Ash's group could go exploring in the submarine, keeping communication via radio. Adam and Evelyn continued to keep contact until Team Rocket suddenly appeared and fired underwater missiles, and radio communication was finally cut off when Adam pursued a Relicanth through a riptide.
After an hour, a relieved Evelyn got a radio response from Adam to say he was returning to the surface. Once aboard the ship, Evelyn scolded Adam for losing contact. She then explained that she had been tracking Team Rocket on radar since they escaped the Relicanth cave with the treasure, and brought the ship to Team Rocket. After Team Rocket was sent blasting off, Adam opened the chest to find a bounty of Green Shards. Evelyn admitted that could make their own jewelry from the Shards to sell to customers, and promised to give May the first necklace they made.
