Sophie didn't have time to whisper the incantation that would allow her to breathe underwater. The fall from Jack's porthole to sea level was much shorter than she had anticipated. Frustrated with herself and now rather wet, she floated lazily to the surface and took a breath before ripping her dress off. The snake had returned to her wrist as soon as she hit the water. Soon, she was completely naked, in all of her tattooed glory.
She spit out the cold water in her mouth and gasped "Volos Pullus!" Then she turned her body over so her back was revealed to the air and her face was underwater.
To an on-looker, it would appear that black wings were growing from the water. In fact, that's exactly what Aidan saw, after he had ran to the deck and looked over the edge of the Black Pearl in search of the girl. Needless to say, the already shaken pirate was near fainting.
Meanwhile, Sophie felt the raven wings grow to their full potential and she stretched them before bringing them down swiftly, almost to the water, to lift herself. Once free of the waves, she flapped the wings harder and gained altitude.
The day was clear, and the shores of France and Britain were out of sight now, so Sophie allowed herself the pleasure of a short flight. The wings, which were roughly five feet in length each, propelled her to the light, fluffy clouds. She let the sunlight wash over her and relieve her of the cold, cold water that she had just plunged into. While the day was cool, Sophie didn't notice.
Aidan had fainted when he saw Sophie, naked, with large black wings protruding from her back, launch into the clear sky and circle around. Now a crowd of crewmembers were gathering around him. The commotion roused Jack, and he came to the deck. After taking a brief look at Aidan, Jack had walked to the helm. Leaning on it lovingly, he looked to the horizon.
Suddenly, a large black thing swooped down, skimming the water, coming towards the Pearl. Its wings were humongous, feathered objects that blocked the view of the body of the creature. Only momentarily, though. And when Jack saw its body, he could not believe his eyes.
There was Sophie, in her birthday suit, a large set of wings behind her, swooping up towards the sun. For a moment all was frozen in Jack's mind. He didn't ponder his sanity. He didn't question how cold she must have been. He didn't even wonder how Sophie had hidden wings from him.
The only thought that came to his mind was, "Bloody hell, she'd be a riot in bed."
Sophie, unaware that Jack was watching, landed carefully on the quarterdeck at the bow of the Black Pearl, where her wings retreated. Content that the crew was busy with Aidan, who was just waking up, she tiptoed, covering herself, down the stairs to the lower deck, then down to the Captain's quarters.
Jack, still at the helm, smirked. "That's very interesting."
