If Jack survived Titanic

Swim!

The water was ice cold, but neither Jack or Rose could feel that at this point. They were so focused to not lost their grip. But even though they tried their very best, they couldn't keep it. Rose managed swim up to the surface, but Jack was dragged deeper down into the ocian with the ship.

Rose was thrown into panic. After taking a deep breath, she started calling out Jack's name. She realised how many people there were in the water. She got mute for some seconds because of the shock. Than, she started looking after Jack. She started to feel how freezing cold the water was, but she kept fighting, as she had promised herself to do. She kept calling for Jack.
"Jack!!!"
She became scared and extremely worried. Were was he??? She couldn't dare to think about where he could be if not somewhere on the surface.
Suddenly, she went under water. She had a lifebelt, so she fluted better that them who had not, and someone thought it was a good idea to use Rose to flote on. Rose fought to get some air in her lungs, but it was hard.
"No!" she screamed.
She tried her best to keep calling for Jack
"Jack!!!"
"Rose!!!"
It was him.
"Get off her!!!" he shouted.
It's hard to describe how satisfying it was for Rose hearing his voice at the time, because it meant that he was still alive.
Now, Rose could swim and breath normally.
"Rose!"
"Jack!"
"Swim Rose, I need you to swim!"
Now, they were on their way from the crowd. Rose started to feel once again how cold the water actually was. She found it very hard to move fast, but Jack pushed her to do her best.
