Imagine: Castiel falls in love with a mermaid. (I kinda tweeked it)

Summary: Lynne use to be a zanna, but is now is a human, but she still has her zanna form. Will a certain blue eyed-angel return the same feelings for her when he finds out?

Lynne had been with team free will since they discovered her passed out cold in the forest. She didn't hunt with them. She mainly just lived in the bunker with them. She, of course, didn't tell them everything about her. She was afraid they would think she was a monster which she wasn't at all. She is or was a zanna or better known as an imaginary friend. She remembered her last child Amelia. She had the curliest red hair and freckled face. She was reaching the age where most kids started to not believe in her kind. Lynne remembered the day fondly.

"I wish you real Lynne," the little girl said her sad smile not reaching her light green eyes, "that way we wouldn't have to say goodbye,"

"Me too Amelia," Lynne said.

The next thing Lynne knew she was waking up in the middle of the forest when Dean, Sam, and Castiel found her. Embarrassingly she was not clothed. She had acted like she couldn't remember much. She surely couldn't tell them she use to be a creature only seen by kids who was a mermaid with wings. She had become very fond of her new family quickly. She loved teasing Dean about eating better since being a mermaid she only ate vegetables and fruits. Her favorite was kelp. She was always daring Dean to try it. He, of course, would roll his eyes and walk away.

Sam was always a good listener. If she needed to vent or a good hug he was the one she ran to. He was the one that had gotten her into books. She had read books before, but they were mainly kids books. Ones that taught you your ABCs and stuff like that. He had shown her books of so many different genres from lore to fairy tales. She was amazed after reading The Wizard of Oz and finding out that Oz was a real place their sister Charlie had traveled to before she had sadly been killed.

Then there was Castiel. An angel in every good sense of the word. She smiled at the thought of him. His beautiful, deep, blue eyes. His little smile when he showed it. The adorable way he would talk. His cute little confused face he would make when he didn't understand something. She was crushing on him. Being around the angel always brought her happiness. She wanted so much to tell the angel how she felt but didn't know if he would accept the love of a Zanna turned humanish. She still turned into a winged mermaid when she was in the water. It was one of the reasons she only showered when everyone was gone. "How could I get Castiel to understand?" she asked herself.

"What do you need me to understand Lynne?" the angel asked appearing from nowhere. Making that adorable confused face. She didn't mean for him to hear her thought.

"It's nothing Castiel, sorry," she said hoping the angel would let it go. He smiled a little and sat beside her.

"Lynne," he said, "if you need to tell me something you can. I will always be here to listen,". She sighed.

"I do have something I've been keeping from you," she said, "I've….developed feelings for you Castiel,". He made his confused face again. She swore it was one of the many reasons she was falling for him.

"What do you mean?" he asked.

"I'm starting to," she said thinking for a minute, "fall in love with you,".

"Oh," he said, "I understand,".

"It's ok if you don't feel the same," she said, "we'll still be friends,". He smiled a little more as he took her hand in his and brushed his lips softly against it. The feeling caused a small shiver to run through her.

"Lynne, I feel the same way," he said a small blush forming on his cheeks, "I wasn't sure how to bring it up to you,".

"Really Castiel?" she asked. He looked into her light green eyes as he tucked a lock of her light blonde hair behind her ear. His deep blue eyes sparkling. He leaned in and gave her a soft kiss on the cheek.

"Really," he said. She could feel her cheeks warming. She didn't expect another sweet, little kiss.

"Before I get my hopes up Castiel," she said standing up, "there is something else I need to tell you and then something I should show you,".

"What is it Lynne?" he asked standing up too.

"Can you zap us to a secluded beach please?" she asked, "it'll be easier to explain,". He nodded as he hugged her to him tight and soon they found themselves on a quiet beach. The waves of water making the only sound around.

"What do you need to tell me Lynne?" he asked, "are you ok?". She took a deep breath and explained to him how she use to be a Zanna until her last child's wish somehow come true.

"So you use to be a Zanna?" he asked and she nodded, "but your human now?".

"That's the part you need to see," she said, "just watch,". She headed into the water. When she got deep enough she dove down and when she did Castiel noticed a mermaid tail shimmering with different shades of green and purple. When she came back up she flew out of the water. Castiel's eyes widened a bit at what he saw. Not only did Lynne have a mermaid fin, but she had a set of wings. They were smaller than angel wings but fluffy. They started off light green and faded into a light purple at the feather tips and they sparkled. "I still have my Zanna form," she stated. Castiel noticed a sad look on her face. He spread his wings and flew up to her.

"You're beautiful Lynne," he said taking her hands in his, "why do you look sad?".

"I'm a monster now," she said, "if the boys find out they'll kill me,".

"You are not a monster Lynne," Castiel stated, "You are not like the mermaids they've dealt with. You would never hurt anyone. Your wings are unique, but you're not any type of angel. I will talk to them and I will let no harm come to you,". She smiled as Castiel pulled her close and there above the sparkling beach water they shared their first kiss.
