DarkAngel1994's Disney Princess Challenge, with a twist!

"Mom!" Caspian called out.

"I see you brought your wife," Morgana said and gave them a mocking bow. "A pleasure to meet the royalties."

"Enough of the chit-chat, sea snake," Erika growled. "Unhand our son and get out!"

"Not a chance!" Morgana giggled and pulled Caspian against her side. "Your baby boy's all mine. We made a deal."

Caspian hung his head in despair, avoiding his parents' glance. "I'm sorry..."

Aurora was in tears at the sight of her son.

"It's going to be alright, Cas," Erika said softly. "We'll find a way to free you from this bargain."

"I'm afraid it's impossible," the sea witch said. "In order to set free your son, there's going to be an exchange to be made."

"What kind of exchange are you talking about?" Erika asked.

"A soul for a soul. You give me your soul, and lil' Cas goes free."

"Erika..." Aurora whimpered.

The blond woman looked at her wife and son, then at the sea witch, and sighed heavily. "Alright."

Morgana smirked and snapped her fingers, causing Erika to stiffen. A dim glow surrounded her body and left Erika, leaving only a hollow shell as she collapsed with a heavy thud.

"MOM!" Caspian cried as he watched Aurora kneel down beside her wife, tears running down her face.

"I would do the same to you, Mrs. Lothario," Moragana said. "But where's the fun when you get to witness me taking out your son."

Meanwhile, Makoa and Natsumi were dealing their own problem. Morgana's daughters broke into the house and attacked him and the Yoshidas.
They managed to knock the sisters out and threw them in the bathroom until the bigger problem was taken care of.

"You said you would set him free!" Aurora shouted.

"Must've slipped my mind," the sea witch giggled and used her power to freeze Aurora before walking over to the frightened merman. He wasn't fast enough, due to the lack of legs, and was pinned to the ground when the sea witch grabbed his throat.

At that moment, Ren stirred awake and sat up, clutching his head. He looked over to his right to see his uncle helping Lilo up and spotted Caspian gasping for air in the sea witch's grip.

"Any last words?" Morgana asked.

"Drop...dead..." Caspian rasped as he tried to push the woman off of him.

"Good enough."

With that, Morgana raised her clawed hand and was about to land a fatal strike on the merman...when she jolted at the sudden pain on her back. She looked over her shoulder to see an enraged Ren and smiled softly.

"Ren, my love..." she said and let go of the now unconscious merman. "Why would you do this to your own wife...?"

"You are not my wife, and you will never be!" Ren growled, causing the woman to flinch. "Not only have you hurt my love, but also our friends and family. You will no longer harm anyone."

Morgana felt her life drain rapidly as Ren took the dagger he found out of her back and collapsed on the ground. Her body withered, then melted into a puddle before being absorbed into the grass.

Makoa and Natsumi jumped when they heard splatters behind the closed door. He took a peek inside and closed the door instantly, feeling sick in the stomach.

Aurora leaned back as her wife's body glowed and watched as Erika let out a loud gasp and sat up, breathing heavily. The brunette woman knocked her wife down, wrapping her arms around Erika's shoulders, and cried.

Erika smiled as she held her weeping wife and spotted Ren checking over Caspian. She noticed her son's merman tail and remembered what Morgana said about the deal he made.
