"HURRICANE COMING! STAND FAST, SECURE THE -RIGGING!" A crewman shouted causing the entire crew to panic as the wind picked up and the rain began to pelt the ship. Castiel looked around him, gripping onto the side of the ship with all his strength, preying that he could hold on. The rain came down harder and harder, and the wind was blowing faster and faster. This caused Castiel's grip to weaken, throwing him from the side of the ship and back into the water. Dean struggled to get the ship under control, but failed miserably and the ship headed straight for an oncoming rock.
"LOOK OUT!" Dean shouted. The moment the ship hit the rock, the entire crew was hurled off the deck and into the water. Sam was silently thanking god that one of the crewmen had already released a rowboat so everyone climbed inside. What happened next was completely unexpected; A lightning bolt struck the sail, setting the entire ship on fire. The whole crew, as well as Castiel, watched horrified.
But Dean quickly realized someone was missing... And he realized this when he heard the barking from aboard the ship.
"IMPALA!" Dean screamed, diving out of the rowboat and swimming back onto the ship. He held out his arms desperately, trying to avoid any flaming debris headed his way. "Jump Impala! C'mon baby jump, you can do it Impala!" Dean shouted to his dog who finally jumped into his arms. Dean ran haphazardly along the deck of the ship with Impala in his arms, headed for the ladder once more. But then, Dean's foot broke through one of the weak boards in the ship's deck, the force causing Dean to throw Impala over the side. Dean pulled and pulled at his own boot furiously, but it wouldn't come loose.
"DEAN!" Sam shouted to his brother, but Dean knew what was about to happen. The ship had been carrying gunpowder for the fireworks for Dean's birthday party, and a flaming piece of the ship's mast had broken through to the barrels of gunpowder. Dean closed his eyes and tensed when he felt the explosion start.
KABOOM!
The entire ship exploded, pieces of debris scattering the dark ocean. Castiel and the other crewmembers watched helpless and horrified. Castiel's eyes widened before he quickly dove under the water, searching relentlessly for Dean. Searching among a pile of debris, Castiel finally spotted him just before he fell under the watery surface. Castiel dove underwater, swimming fast enough and grabbed Dean's shoulder, gripping him tight as he pulled him up to the surface. Castiel made sure he kept Dean's head above the water so he could breathe, which was a fairly difficult task. Swimming and swimming all night, Castiel finally found a patch of land where he laid Dean onto the sand.
"Is he... Dead?" Castiel asked Adam nervously, who was flying around them.
"It's hard to say." Adam whispered then taking Dean's foot and putting it to his head. "oh... I cant make out a heartbeat." But Castiel stopped Adam abruptly when he noticed something.
"NO LOOK! He's breathing!" Castiel sighed loudly, putting his hand on Dean's face, "He's so beautiful.." And then, the merman began to sing.
"What would I give to live where you are? What would I pay to stay here beside you? What would I do to see you smiling at me? Where would we walk? Where would we run? If we could stay all day in the sun, just you and me, and I could be, part of your world!" Castiel sang lightly, and Dean's eyes fluttered open, catching a very brief glimpse of Castiel, his hand touching Castiel's hand.
"DEAN!" A voice called out, startling Castiel enough to cause him to dive back into the water. The sound of a dog barking quickly joined the voice. "DEAN! Oh my god, you must really enjoy giving me fucking heart attacks don't you?" Sam groaned loudly, picking up his waterlogged brother.
"A-a boy, rescued me! He was... singing! He had the most beautiful voice!" Dean exclaimed before growing faint and falling back into Sam's arms.
"Seriously Dean, I thing you've swallowed a bit too much seawater... C'mon." He helped his brother up off the sand and towards the castle, unaware that Castiel was still watching them from being a rock. At this point, Gabriel and Bobby had joined him, unfortunately seeing the entire scene unfold before their eyes. Gabriel wanted to pinch Castiel's arm off for what he had done, but he tried hard to remain calm.
"We just oughta forget this whole thing ever happened! The sea king will never know! You wont tell him?" He asked Bobby who shook his head, "Good, I wont tell him! I will stay in one piece!" Gabriel prayed. But as usual, Castiel was paying no attention to him when he started to sing again.
"I don't know when... I don't know how... but I know something's starting right now! Watch and you'll see... someday I'll be... PART OF YOUR WORLD!" Castiel sang out to the prince, wishing he could hear him... But at the moment, it seemed someone else was listening.. Someone who most likely shouldn't have.
