As the water rose, due to the storm, the channel deepened, allowing the Basilosaurus to swim through the gap in the coral, into the bay. Perhaps they had been here before; maybe this was an annual thing. The terrified Dorudon bunched closer together, attempting to protect their young from the larger predators. The Basilosaurus, paying them no heed, swam, slowly, but remorselessly towards the Dorudon pod. Drew turned to Alice, "Get the Dorudon through the portal! I'll keep these guys occupied!" Alice turned to him and said, confused, "What are you going to do, poke them?!" Drew smiled, "I got an idea."

At this statement, Alice smiled and nodded, before saying, "I knew you would", before she turned and swam towards the Dorudon. The terrified whales bunched closer together as she approached. As Alice got closer, she said, trying to sound as soothing as she could, "Don't worry, don't worry, we're here to help you. My friend is going to scare off the Basilosaurus, whilst I get you somewhere safe. She lifted the portal remote, pressed a button and the portal whirred into life. The Dorudon approached hesitantly, as if uncertain about whether or not to approach this strange new object. As if to give some further encouragement, Alice grabbed the bait bag and emptied it through the portal. With this, the Dorudon did not need much encouragement. They swam through the portal, after the bait and into the present.

Meanwhile, as Drew swam towards the Basilosaurus, he activated his in-suit communicator and said, "Leon! I need you to transfer the Basilosaurus calls we recorded to my handheld." Leon's voice rang in from the other end, perplexed, "Why?" Drew smirked, "A distraction." Leon mumbled over the communicator, "Okay…" After a minute or so, Leon said, "It's been transferred." Drew smiled, lifted his handheld, pressed a button and a long, low, mournful-sounding call echoed through the water. The Basilosaurus stopped in their advance and turned around, almost in unison; there was another apex predator here, but where was it? Slowly, remorselessly, they began to advance towards the source of the sound.

Once they had gotten close enough, Drew took off, swimming as fast as his legs could carry him. The Basilosaurus followed him, their prey drives activated. As the Basilosaurus pursued him, Drew smirked; this was just what he needed. Escaping some prehistoric predator armed with nothing but his wits. He was starting to feel like his old self again.

If he had been in any serious danger, he would not have attempted this plan. The bay was too shallow for the Basilosaurus; they were too cumbersome in the bay. Their great size was turning from an advantage, into a handicap. And, besides, they were focused on the recordings indicating there was another Basilosaurus on their turf, not the strange little creature that was swimming in front of them.

Suddenly, Alice's voice rang in from the in-suit communicator, "The Dorudon have gone through; it's done." Drew smiled, "Perfect. You get back to the boat; I'll get these guys through the portal." Alice's voice was tinged with worry, "But what are you going to do?" Drew smiled, "Don't worry; I know what to do." There was a brief pause and then Alice replied, "Fine." Drew looked to see Alice swimming away in the distance, towards the boat. Once she was gone, Drew lifted the remote, activated the portal and flung the communicator in.

Unchanging their trajectory, the Basilosaurus followed the communicator, still emitting the call, through the portal, moving as if a single entity. Drew sighed; the adventure was over. Alice's voice crackled over the radio, "We're sending down the shark cage to pick you. After that, I think it's time we all went home." As she said this, the shark cage was lowered into the water, and Drew swam into it. Once he was in and he closed the door, the shark cage was lifted above water and it returned to the Mariner. Drew sighed, "Good plan." Leon smiled, "Think nothing of it, Drew. You know, after six months, you sound like yourself again." Smiling, Drew said, "I feel like myself again". He activated the portal and the Mariner sailed through to the present.

After they disembarked the Mariner, they were met by Jack, who said, "Hi, guys! You are not gonna believe the trip we had", before he trailed off, looking at their stony faces, "You too, huh?"

After that, all the Late Eocene creatures were being transported to their new homes. The Andrewsarchus, Embolotherium, Moeritherium and Arsinoitherium were all transferred to paddocks in a new area called the Mammal Trail. It was decided that the Moeritherium and Arsinoitherium could share a paddock, since they were both herbivores and unlikely to harm each other. They were all either feeding or swimming in the large pool of water that the paddock had.

Meanwhile, the Embolotherium, in a large paddock of their own, were either lying in the shade or browsing on the plants in the exhibit, whilst the Andrewsarchus, who had been given a large paddock near that of the Embolotherium, were all napping in the shade, waiting for their next meal to arrive. The Apidium had been placed in a new exhibit called Family Tree, which would chronicle the evolution of humanity. They were all clambering through the branches, searching for fruit. The Physogaleus had been placed in a large tank in the Aquarium; they were currently swimming around their tank, waiting to be fed.

And the Basilosaurus and Dorudon had been placed in large tanks in a new section called Whale Cove, which would house the many prehistoric cetaceans the team would bring back. Whale Cove consisted of a series of four large seapens, each separated by large glass walls, made out of a large coastal bay on the island, with a wall separating the entrance of the bay from the sea and a series of pumps along the sea wall that pumped water in from the ocean to replenish the seapens. An underwater walkway had been built, which would allow visitors to see the cetaceans when the park opened, whilst a boat tour allowed for surface observation.

The Dorudon were swimming around and exploring their new home, whilst the six Basilosaurus, having divided their new tank up into territories, were swimming around their new home, waiting to be fed. Linda had informed Drew that one of the females, the one they had encountered in the swamp, was pregnant and would give birth soon; the Basilosaurus at the park would soon number seven, rather than six.

All was well at Prehistoric Earth… until the next mission, that was.
