He finds Joe, and they come back to save the rest of the group, who found the Digi-Egg of Reliability, Cody's second Digi-Egg. Cody can't accept the egg because he lied to his grandfather. But thanks to a pep talk from Joe about some lies that can be helpful, Cody overcomes his self doubt and ends up using the Egg. At the end, Submarimon gives Cody a tour of the sea.
