In the end, they returned to the new training involving the Coast Guard. Jason is chosen to wear blacked out swim goggles because Sean finds him to self-reliant. He then gets placed on a cliff without knowing where he is. By accident, Sean, who's hiding close to Jason to make sure that he's safe, gets a rock in his head and needs a Coast Guard rescue.
