"Darwin good hunter," the dolphin chirped.
"Yes, I'm sure that's true, Darwin," Lucas answered, "but right now we have to work on your vocabulary,"
"Darwin hunt fish," Darwin tried again.
"Fine, let me ask the Captain if we are high enough in the water, and staying still enough for you to go out and hunt," Lucas spoke into the yellow vocorder. Then he reached for one of the ship's communicators. "Lucas to Captain," he asked.
"Lucas, what is it? I've just gone to bed," came the reply.
"Sorry, sir, I'll ask commander Ford," Lucas said trying again, "Lucas to Commander Ford?"
"Ford here," came the immediate answer.
"Commander, Darwin is insisting on going outside to hunt. Can I send him out?"
"Yes, I'll open the sea doors for him now," the commander answered, and the door to the moon pool began to shut. Darwin swam off. An hour later he returned with a still-living octopus. He brought it into the moon pool, and let it go, chasing it as it tried to swim away from him. He caught it, then let it go again.
"Darwin, don't play with your food," Lucas admonished.
"Darwin hunt," the dolphin said prodding the octopus with his rostrum
"Are you hunting for food, or because you want to hunt?" Lucas asked him as the octopus swam away as quickly as it could.
"Darwin hunt," the dolphin said again, chasing after the octopus. This time, he finally ate it.
