Craig just tells him that everything is fine. Mitch and April decide that he needs to talk to Craig. Therefore he plans on taking him paddle boarding.
Just before they are about to go out on their boards, Craig tells Mitch that he has lymphoma. The doctors discovered it early and Craig might live for another ten years. When they have paddled out, they are caught in a fog. While they are waiting for the fog to disappear, Craig starts eating a candy bar that he had stored in a compartment of his wet suit. Of course Mitch wants some and they end up losing it in the ocean. Craig tells Mitch that he is going to break up with April. He does not want her to end up without a boyfriend when he dies. Mitch talks him out of it.
