They knew or rather, they must have known. It was idiotic to think heaven and hell would never interrupt their fragile existence…again. That was not how it worked. It had never worked like that; however, heaven and hell could never take away what they experienced during their blissful escape.

For once, Crowley had no intention of driving fast, the slower he drove, the slower their fairytale would end. "Are you sure it's not a trap?" The demon spoke through gritted teeth.

Aziraphale reread the postcard he had received from Muriel urging him to return to the bookshop as soon as possible. "They wouldn't dare be that conniving. I trust them."

"Right, well, we can trust them but I'm not, nor will I ever, trust your lot upstairs." The demon spat. "So what? They suddenly realized their supreme Archangel is missing…after three months? Please. It's a trap."

Cassi leaned over and read the postcard over Aziraphale's shoulder. "If you have to go back to heaven, papa, may I have your bookshop?"

Aziraphale grunted. "I'm not going anywhere; I believe they just want to have a talk. Probably wondering where I have been."

"Oh, yes, a talk!" Crowley elaborated on the k. "Because heaven is so very understanding when it comes to things not going how they want them to go, puh-lease. Don't ever trust and angel, Cassi, don't you dare. Think they are the good guys when in reality, they are just as crazy as demons…sometimes even worse." He grumbled.

"I rather you not insult angels at the moment."

"Right, right I apologize. What I meant to say, Cassi, is… trust no angel except for your father here."

"Crowley!" Aziraphale eyed him.

"No no, don't give that they are holier than thou look. You know I'm right or should I remind you about how you were almost casted into a blasted hell fire!" The Bentley's tires screeched as Crowley pressed down hard on the brake pedal. Angel and demon existed in the car, taking in their beloved bookshop. It was a sight for sore eyes although both wished they had come back on a better occasion. "So, what? You're just going to march in there and talk your way into their good graces?" Crowley's body moved without thinking, following Aziraphale into the bookshop. Aziraphale stepped inside first, seeing no sign of Muriel. "Probably leaving again because heaven always comes first, doesn't it?" The door shut behind them.

"That's quite enough of that!" Aziraphale's face was red in both anger and annoyance. "I get it, you hate heaven! You hate angels! You hate everything but don't throw me leaving us back in my face."

Crowley huffed and felt angry at himself. Those hurtful words did not mean anything as he had fully forgiven his lover. He knew he was angry at the possibility that Aziraphale might be going back to heaven but deep down, he knew it wasn't the angel's fault. It was that damn society he was from. He could not help that he belonged to heaven. They were a family that had become quite close during the last three months with Crowley's and Aziraphale's relationship blossoming into something incredibly and truly magical. It was beyond what either of them could have imagined it would be. They communicated now, they shared their most intimate thoughts, they got to know each other better, and most importantly they were finally together after millennia. Crowley did not want to live in a reality where all this might be a dream and he was actually sleeping the days away in his bed and the year was 1863.

Crowley stepped forward and sharply exhaled as he placed his hand gently on Aziraphale's neck and pressed his forehead on his. "I'm sorry." His voice was soft. "You know I don't…don't mean it."

"I know you don't." Aziraphale caressed Crowley's cheek. "You know I won't ever leave you again. Why would I leave you and…Cassi?" He looked around frantically until the bell to the shop rang and Muriel walked in.

"Ah, Muriel." Aziraphale greeted as Crowley backed away. "I received your postcard."

"I'll go look for her." Crowley mumbled.

"Mr. Supreme Archangel, sir and Mr. Crowley." They grinned all too happily. "Yes! The Metatron came by and asked about your whereabouts. He did not seem pleased, and he said I better get you here as soon as possible or I will not hear the end of it, whatever that means. He's waiting in the coffee shop."

Crowley halted and exchanged a look with Aziraphale. A second later they were bolting out the door. To their horror, the Metatron stood in front of the coffee shop talking to their daughter as she stood near the Bentley, Hex in hand. "That is an unusual name." The Metatron could be heard as the couple approached. "Some say it's bad luck to even mention the word."

"I did not name him." Cassi smiled as she bounced the Persian in her arms. "His owner passed away and I promised to look after him for her." Cassi looked beyond the Metatron's shoulder and stepped away from him as she noticed her parents come close, Crowley waving his hand to back away from the stranger.

Crowley placed his arms around Cassi's shoulder, protective dad mode on. "Ah, if it isn't our long-lost supreme Archangel." The Metatron raised an eyebrow as Aziraphale placed himself before the celestial being and his family. "How was your little vacation?"

Aziraphale smiled nervously. "Ah, yes, well…" He took a breath and raised his head. "It was jolly good…quite eventful and I - I realized that I do-"

"If you needed a break from the job, all you needed to do was ask. Not disappear for months without any notice." The Metatron eyed Crowley. "I know it's hard to leave something you knew for millennia but the supreme Archangel of heaven can't just leave when they want to." He tilted his head to the side, trying to get a better look at Cassi. "A beautiful nephalem you two created." Aziraphale glanced back at Crowley and Cassi then back to the Metatron. "While nephilims are part angels or demons and part humans, they are relatively mild compared to an offspring of an angel and demon, also known as a nephalem. More powerful than their creators and any other celestial or occult being." The Metatron's eyes were on Cassi. "Depending on which parent has the stronger feelings while creating the offspring, that's how the nephalem will view the world." He smiled. "I see in this case you, Aziraphale, had the stronger feelings and therefore this child knows not about hate, only love. She emits it like a shining star blinding the night sky."

"Yo-you knew about her?" Crowley questioned in anger.

The Metatron shrugged. "It's my job to know the existence of all angels, even if they are half angel."

Crowley eyed him carefully. "There's another one." He stated blankly. Aziraphale turned to him.

"Always keen, that one." The old man chuckled. "The other one was not as fortunate to be more angel than demon, I'm afraid. Positively engulfs one with hatred."

Aziraphale's eyes widen, meeting Crowley's once more. They had come close to him, Cassi had come close to him, the other nephalem in existence. The boy in the shop and judging by how casual he was with Cassi; he knew exactly what she was. "What do you want?" Aziraphale spoke up.

The Metatron shrugged once more. "The other one is pure evil, even for this world. We have been looking for all halflings in trying to find him. We have also been tracking your little one over here because we believe she can eradicate him."

Crowley blew air through his nose. "Get in the car, Cassi." He opened the Bentley's door. "Now. Cassiopeia." He commanded sharply when the girl did not move. He slammed the door behind her, waiting for Aziraphale to get in afterwards as well. Crowley could see Aziraphale's mind turning behind his eyes. He knew the angel had come to the same conclusion; heaven wanted to use their daughter as a weapon against the evil entity. In heaven's eyes, in all angel's eyes, they were required to do the right thing. Even if the right thing meant destroying lives as if they were nothing. They were the "good guys" after all, meaning heaven's plan had to make sense. Meanwhile, Aziraphale was his lover, Cassi's other father but his identity was also that of an angel.

Aziraphale shook his head slowly and sighed. "I rather you look for another supreme Archangel." He began his steps towards the passenger side of the Bentley and opened the door. His whole demeanor changed as if he was ready to battle. "And don't you dare approach my daughter again." He slammed the car door shut.

Crowley grinned ear to ear and sucked air through his teeth. "Erm…what can I say, being a parent changes you."

St. James' Park and a familiar bench was the perfect breather to take in new information. The park had become the place where many memories were created. Even the current one where a demon and angel discussed what to do next as they watched their daughter a few feet away take selfies with her cat and some ducks. "There's some evil in her, at least a little bit." Aziraphale began. "Sometimes she can be cunning and vengeful but…"

"Nah, her evil is that of a naughty toddler or child." Crowley sighed. "We have been with her for months and she's literally the epitome of good…of light…" he turned to his lover, "of love."

"We created an entity more powerful than an average angel and demon, more powerful than us. To think someone else had done so as well. You don't think it was Gabriel and…"

"Of course not, Cassi was created almost a hundred years ago, Gabriel and Beelzebub's relationship is new."

"Dad?" Cassi called as she came towards them. "Do you have peas? I want to feed the ducks." Crowley sat up slightly and miracled a small bag of frozen peas. She placed Hex in Aziraphale arms, taking the small bag. "I could have done that."

Crowley smiled politely. "Really? I don't recall revoking the no miracle rule."

"But heaven already knows about me, and that I am with you, surely I can go back to using miracles."

"We rather you didn't, darling, better safe than sorry."

Cassi exhaled sharply. "You guys are no fun." She grumbled as she walked back towards the pond. "Making me exert myself like a human."

"You know," Crowley tapped Aziraphale's shoulder, "maybe she does have wings."

"Hmm?"

The demon leaned into his angel lover and sniffed. "The old bloke suggested she is our biological offspring, not just another miracle. Basic genetics, angel, er, she has my hair, your lovely features, except for my nose and all that." He shook Aziraphale slightly as the angel pursed his lips. "Ngh…I swear, angel, you are so clever but when it comes to basic things…we both have wings…so…"

"So…?"

"Exactly, so, meaning, it's likely she has them as well…we might have even passed down some of our own abilities onto her, not just capability of performing miracles."

Aziraphale looked upon the girl. "Do you think she can stop time like you?"

"Eh…probably." Crowley inspected her thoroughly from afar. "I'm not quite sure how to even teach her to take them out…the wings, I mean. Hmm…wings are just there, you know? They have always been there…it-it's a natural thing. Is it, um, something we can teach her to do? Like reading…can't recall how I managed to learn that…it just was…is?"

Aziraphale stood up and handed Hex to Crowley. "You're rambling, dearest." He smiled and kissed the demon's forehead before he met Cassi down by the pond. "Don't give them too much or you'll spoil them." He placed his hand behind his back.

Cassi threw another handful of peas into the pond. "From what I've gathered, you two have been spoiling them for years."

Aziraphale looked back at Crowley and then back at Cassi. "Ah, I cannot deny it."

The girl was silent for a moment as she watched the ducks dip their beaks into the water, chasing the round veggie. "Papa?"

"Hm?"

Cassi's voice was low. "If I was created more demon than angel, making me full of hatred like that other nephalem, wou-would you and dad still want me?"

Aziraphale's pleasant expression changed to a serious one. "Why, my darling girl, of course we would! We will always want you, will always love you no matter if you were a demon, an angel, or even human. You're our daughter no matter what you are or choose to be."

Cassi turned to face Aziraphale. "Then why does heaven want that nephalem dead? Did he do something wrong? It's not his fault he was created the way he was."

Aziraphale's expression softened as he looked at his daughter. "No one is to blame, Cassi. Heaven is…like dad said, it's complicated. They," he sighed, "believe they are the righteous ones out of all beings created. They do not see the…the bad they have done to earth, especially to humans. Who's to say this boy is as evil as they infer and even if he is, well, there's no reason why he should be, as the Metatron suggested, eradicated. Perhaps talking to him first? No one should be eliminated because of who and what they are."

"Dad said you were like them not too long ago. You would have eliminated the other nephalem without question."

"Uh, well, I was indeed. Took me a long time to realize not everything is black and white, shades of gray will always be in between. But if it wasn't for dad, I do believe I would still be in that sort of mentality. What we have gone through and the love I have for him made me realize heaven can also be the bad guys."

"Demons can definitely be good guys."

Aziraphale cupped his chin and raised an eyebrow. "That, I'm not quite sure. Apart from dad, I have yet to meet one who is not all that bad."

"Dad doesn't really count. He only pretends to be a demon."

Aziraphale chuckled. "Don't let him hear you say that, or he'll rant nonstop on how positively evil he is. Although, even if he was, I wouldn't stop loving him and I do lo-," he looked over at Crowley who had Hex in midair, the cat hissing while Crowley hissed back, "um, hm, love him very much. Now," he turned back to the girl, "shall we get on? It's getting rather late and we did say dinner at the Ritz while we are here."

"Da-damn, angel…" Crowley grunted as continued to move his hips, "who knew…argh…yo-you had…hah…it in you to tell…tell…fuuuuuck…" The demon was close and he could feel Aziraphale's ending coming along as well. "The old…ngh…bastard t-to…fuck off…" The angel's hand pumped the demon's desire one last time, making him spill the warm liquid onto the angel's stomach. Crowley shook as his orgasm continued while Aziraphale's thrusts became erratic until he too spilled inside of his demon lover. Panting, Crowley leaned down as he sought Aziraphale's lips. "Fuck, how I love you." He kissed his lover full of hunger until he could feel the angel become hard again. "I swear, your unmatched appetite…" With that said, Crowley gave his lover one last gentle kiss before he sat back up to his straddling position and began to slowly rock his hips once again.

Aziraphale brought out his sticky hand from between them and, without a second thought, Crowley began to lick his angel's hand clean. "I'm not sure what came over me." He looked up at Crowley. "He made me so mad."

A popping sound echoed as Crowley removed Aziraphale's digit from his mouth. "It's about time someone told him to fuck off." The angel placed his soft hands on Crowley's hips, guiding his movements. "Losing two supreme Archangels to demon temptations can't be good for his reputation."

"I don't suppose it can."

Crowley, noticing Aziraphale's worried expression, halted his moments. "What's wrong, angel?"

"I'm worried."

"About?"

"What…what if they take her from us? By force, somehow or…he knew about her and didn't say anything. When he offered me the position, he knew about her."

Crowley leaned down and cupped Aziraphale's cheek. "Yes, he knew about her, but it solidifies the undeniable fact that he is a bastard. No one is taking anyone anywhere, angel. I'll make sure of it." He kissed the corner of Aziraphale's mouth. "I promise."

"Really?" Aziraphale asked with eager eyes.

"Would I lie to you?" Crowley smirked and kissed Aziraphale's nose.

Aziraphale traced Crowley's lower lip. "To this day I have not the slightest idea if you have ever lied to me."

"Really?" Crowley chuckled. "Between you and I, demon and angel, who was the one who lied about not knowing where the antichrist was? You hurt my feelings, angel." Aziraphale rolled his eyes, making Crowley smirk. "Right, now, turn around…it's my turn."

Somewhere else inside the cottage, technically outside in the gardens, Cassi inspected the page in front of her. According to her dad's The Extremely Big Book of Astronomy book, one of Saturn's moons, Titan, could be becoming another earth. Definitely not soon, but maybe in a million years. The young girl had set up her telescope just right to inspect the odd moon further.

"I simply can't understand why you don't just go visit if you're that curious." A familiar voice sounded from one of Crowley's apple trees. "Visit all of the Milky Way and beyond for all that matter." The visitor took notice on how Cassi shuddered as if she was suppressing a stabbing sensation within her. "Sorry."

"No need." Cassi spoke, letting out a small breath. After she willed herself to get used to the intruding sensation, she smiled at her visitor. "You're late, Elliot."

The nephalem came from within the dark garden, holding an apple in hand. "Ah, I'm sorry again." He took a small bite from the apple and offered a taste to the redhead. Cassi took the offer and bit into the red fruit. "Won't happen again."

Cassi squinted her eyes playfully. "Now, that's a lie." She scoffed.

A wicked smile spread across Elliot's face. "Obviously."

A/N: The way I described nephalems is depicted from the game Diablo. They have a whole lore of it, quite an interesting and fun game. Meanwhile, I did manage to write the full-on spicy scene of their first time however, this fic if rated T so decided to keep it T. I will most likely post it in a new fic, like an additional chapter or something like that. Please let me know if anyone is interested.
