________________________________________________________________

You were covered in darkness, but you were adjusted to the darkness, you lived in the dark with your clan who usually swims in the parts of the ocean where the light just barely touched your skin. 

However instead of the comforting warmth and assurance, you had when you were a woman swimming with your clan, your family, it was a lingering warmth and a reassurance that had made you realize you were dreaming and not of your memories. 

“(Y/N) you have met an interesting fate having fallen for Lucifer,” a voice echoed around you. You looked around in the dark space to search for the voice but found no answer to that.

“I would not have known of your existence if you hadn’t gone out of that water, it’s strange what this world has created once I left it.”

“Are you the moon? What do you mean by that? All I know is what I have been taught and seen when I was in the ocean”

“You could say I am the moon, but I am more than that and also less than that at the same time. I affect the world around me indirectly but you have caused quite a stir where I am at with your involvement with Lucifer, I wish you the best of luck and the best of health.”

With that, you were startled from your sleep by pressure on your shoulder, and you opened your eyes to see Lucifer smiling at you. Once he saw you were awake he went to say, “Good morning my dear, have a good dream?”

“Funny you should mention that, I heard a voice say that they were the moon, I think anyway. I don’t quite remember what they said but I remember your name,” you say as you start sitting up from the bed.

Lucifer sat down next to you as he took in what you said, humming in thought, he turned to you and patted your shoulder.

“Well the only one I know that could do that, would be my Dad, but I don’t know why he would want to talk to you.”

After a couple of days, you have gotten well versed with different aspects of human life and culture, mainly you are not allowed to eat spaghetti with your hands. You also have gotten interested in the tv that had got you basically hooked on the subtleties of different subsets of human culture, one being that if bad men are about to hurt you you can beat them up.

“Anyway, darling remember when I was talking to you about my consulting job for the police?”

You nodded remembering the different stories of his workplace along with his partner, Chloe. She seemed weird but nice from what you heard from him. 

“Well, I have to go in today there is a case that the police department says they need my help with,” Lucifer continued, “and I want you to come with me.”

“I would like to, is it going to be like what I saw on tv with how they deal with violence?” you asked.

“Kind of, it depends, now love let’s get you ready for the day and we can get going.”

--------------------------------------------------

You and Lucifer walked into a one-story house it looks plain and forgettable with its beige outside paint and white shingled roof. There were also some beautiful hydrangea bushes in the front, and you noticed them because they were the only splash of color in the whole property. There were police officers around the property and you saw one documenting the bushes. You tilt your head as you were stalling to enter the house and saw footprints underneath the bushes. 

“(Y/N) are you okay? Come on,” Lucifer urged on. He leads you into the home, and you immediately see the crime scene.

 It was an execution. Plain and simple. The victim was a young woman from what you saw, and she was shot point-blank in the back of the head as she was sitting on her couch, she probably knew the killer, since the tv was still on. 

The aquarium was direct across from the living room, and you saw the fish in there was trying to get your attention. You can hear the voices of the fish repeatedly crying out, “He hurt her! Help her! He was her friend” You looked at the aquarium and the fishes seem to surround you as they try to talk to you through the glass. ‘Can you show me what he looked like,’ you broadcasted to the fish. 

Lucifer was looking at you confused at what you were doing and was about to talk to you when he got interrupted.

“Oh no, you did not bring a civilian to a crime scene” you hear a voice coming towards you. 

“Ah detective, how good to see you again, and this is (Y/N) she is my assistant and friend,” Lucifer says. 

You turn your head away from the aquarium and saw a stressed blonde woman coming towards you, and you realized that this must be Chloe Decker. She tilted her head with furrowed brows and a hand to her hip as she eyes you. 

“Why would you need an assistant?” Decker questioned.

“You know there are always things that I could miss out on while we’re out here and plus don’t you want someone who can put me in line and in order for once?” Lucifer replied.

“That’ll be the day,” Decker snorted.

You tugged on the jacket sleeve on Lucifer to get his attention to you, and he leaned for you to whisper to tell him the thoughts and profile the fish given to you about the person who committed the murder.

“Oh that’s brilliant, darling, see Detective my assistant just gave us a solid lead to go off of. We have a suspect!” Lucifer exclaimed as he grabs your hand and leads you out of the crime scene.

“Wait a minute can you tell me what means?” Decker ran off to you two.

---------------------------------------------

So the three of you ended up at an apartment building on the opposite side of Los Angeles waiting to interview the suspect that the fish had identified to you at the victim’s home. 

Lucifer ended up filling into Decker that you had deduced based on the footprints outside the house and the way she was killed, it was someone she knew intimately enough to let the person in without a second glance. You just confirmed that for him with the description of the man the fish saw kill their owner, Blaire Wright. He also found that there was a single picture of him and the victim together faced down so he connected the dots to realize that the relationship must’ve turned to an obsession for the man and had gone possessive over the woman. The old “if I can’t have her nobody can” cliche, which made Lucifer quite bored about that trope but you can’t always choose what happens in your cases. 

You all made your way to the apartment building, Decker went to find out from the landlord about the suspect and you and Lucifer were ordered to stay out in the parking lot. You spotted the man that matched the description the fish gave you and the picture Lucifer showed to verify it. His name was Oscar Grant, and he’s suspected to have developed an obsessive behavior over Ns. Wright … and he was heading your way.

Lucifer seemed to be aware of it as he straightened himself and walked over to where the man was walking into the parking lot. 

You felt a strange sensation of being submerged in the water again, you felt heavy and light all at the same time. You couldn’t hear what the two were saying, but you felt the danger and sensation of a cornered animal, and that’s when you felt that you had to move. So you did. Grant pulled a gun but as soon as he did you grabbed his forearm and threw him towards the dumpsters that were ten feet away from him. You may have used a bit too much of your strength. There was now a new dent behind Grant that there wasn’t there before and a shocked looking Lucifer next to you and staring at the gun in between you and the culprit.

You heard Decker walking behind you and you heard her go with a bewildered voice, “How in the-?”

When he came to a few seconds later, he was given his rights by Decker and placed in the back of her car off the police department. While you were walking up to you and Lucifer’s ride you felt a lingering gaze on your back throughout that entire encounter. You just shook your head in an attempt to get rid of that feeling. 

Later on, Oscar Grant ended up confessing to both the attempted murder of you and Lucifer and the murder of Blaire Wright. Decker relented upon the idea of Lucifer bringing you to cases because you ended up being a pretty good asset. 

------------------------------------

Now you were back at Lucifer’s penthouse and you were in pajamas lounging around the bar area in his place. Lucifer was down at the LUX club area taking care of some business that he needed to get done as he told you. 

There was a small pool that he had in his apartment which you found, and you can hear the call of the water no matter its state. So you took off your clothes and went in the pool, your tail and scales came as soon as you were submerged and your whole body was singing with happiness as it felt alive again. 

The more you spend on land without the return of the love that you came out of the water for, your heart will stop beating unless you step back in the ocean. You forgot to tell Lucifer about that specific part of the deal of you coming on land because you didn’t want him to feel the pressure of returning a love that might not be real, to begin with. 

You begin to worry about what might happen if he found out you didn’t tell him the whole truth of your situation to him. You didn’t want him to concerned for your fate, because you never know what might happen there might be a happy ending for you both.

As you were swimming in the small pool brooding in your thoughts you heard the elevator ping, so you peaked your head over the corner of the pool. When you just saw it was Lucifer and no one else you let yourself be seen by him.

“Well hello there, I see you have found my pool then?” Lucifer greeted you. You beamed at him and nodded fervently at that.

“Y’know I never actually saw you as your original mermaid self? Is it alright if I watch you swim?”

“Um sure if you want to, I’m not the most beautiful, there are others in just my clan that have amazing scales and tail fin,” you state.

“Let me be the judge of that, love-” he cut himself off with a mouth agape look as he marveled at your full beauty.

Your tail was massive and the scales decorating and protecting your body were glittering with a rainbow of colors complementing your skin tone. It made you look heavenly and the flowing tail at the end made you look that way even more so.

You became self-conscious at the way Lucifer was just staring at you, so became to fidget under his heavy gaze in the water.

Then he spoke gently, “You are beautiful, absolutely gorgeous. Thank you for letting me see your true self like this.”

“Thank you Lucifer, that means a lot to me.”

The brooding can wait, you have time to be hopeful and to think about that happy ending.
