Jessie was so intent on looking at the ship that she did not notice the water was getting darker. She did not notice until Nate grabbed her arm and pointed up. The others were already swimming up, but he had returned for his distracted sister.

Jessie's eyes widened when she saw the change and she nodded her head to show she understood Nate. There was a storm coming and they had to get back to shore! She turned to follow him, leaving the old ship behind. However, she did not make it far when her tank caught on a piece of metal that was jutting out. Taken off guard, Jessie wrenched around, and did more harm then good.

One of the straps that held the tank to her shoulders, snapped. The heavy tank fell sideways and pulled her down. Jessie fought to rise, and in the process the other strap broke. The tank slid of Jessie's back, yanking her mask with it. Jessie clapped her mouth shut and swam upward.

Nate had not been idle during the whole thing. Seeing she was caught he had turned back to help her, but by then the tank had already fallen from her back. Bubbles filled the water, and Nate swam back to his sister. He grabbed her arm, tore his own mask from his face, and placed it over hers. Jessie breathed deeply.

Nate jabbed his finger back down at the tank, and then slowly swam down. He and Jessie took turns using his mask as they went. The tank had fallen in the door of a partly opened hatch. It was now caught fast. Nate made hand motions to Jessie to tell her he was going to pull it out. Jessie took a deep breath, then handed the mask back to Nate.

Nate tried to work quickly. He grabbed the tank and tried to pull it free, but it was much harder then he thought it would be. The tank was stuck, and he could not get good leverage to pull. Annoyed he let go and removed the mask so Jessie could breath again. While she was using it he thought. By the time she handed it back to him he had a plan.
