Your little devil

Family Man

YES I DID USE A PICTURE OF AN ANTICHRIST. It was the only picture of a kid I had... Sorry.

"MICHAEL!" You shouted, "CALM DOWN!" The young boy instantly calmed down. Lucifer hated naming his only son after his brother, but it had been your brother's name, so you had to insist. Technically his full name was Mihael Castiel Winchester. You had retired your old last name when you fell in with the Winchesters, and it seemed appropriate. You had named Gabriel the godparent, but it felt unfair to not add Cas in somewhere. So he became his middle name.
"How was he?" Lucifer asked, entering the door. You were only 25, but felt thirty with a seven year old child. Technically, he was one. But by the end of this year, Michael would be the same age as you. Then his aging would stay there.
"Daddy!" He ran to hug his father. You smiled and joined them, giving your husband a kiss on the cheek. Lucifer had a lot to keep up with, running hell, being evil, but never letting his child see that side of him. He still became ready eyed when he saw the handprint scar on your neck. It hurt him in every possible way.
"Daddy can we go play with the puppies?" Your son bounced up and down, excited. The 'puppies' he was referring to were the hell hounds. You hated him going down there, but Lucifer had reassured you it was alright.
"Of course Michael! Hey, give mommy a kiss, okay?" You smiled and bent down. Michael hugged you and kissed your cheek. You stood up. Lucifer wrapped an arm around your waist tenderly, then pecked you on the lips. It was December, and you planned on bringing Michael to the bunker for Christmas. Lucifer hated the holiday, so you usually didn't celebrate. He typically didn't even leave hell.
"Hurry back. You still need to pack your bags to visit Uncle Sammy, and Uncle Dean!" Michael's face lit up. He ran out the front door, and Lucifer trailed him.
"Be careful with him. Love you!" You said as Lucifer exited the door.
"Love you, too!" He shouted, closing the door shut behind him. You became worried. You knew something had been off with Michael recently. You searched threw lore books, but nephilim were so uncommon that you didn't find much. Lucifer only knew part of the story. Michael hadn't grown in the last seven months. The first year he was alive he should've grown to his mid twenties already. But there were... other things. Things you hadn't told him, because you were afraid of how he'd react. You didn't realize how long you'd been researching until you heard Michael laugh, Lucifer was carrying him, and they seemed like a normal father and son for a few minutes. You laughed, setting your book down. Lucifer set Michael down to greet you.
"Go grab your things, we need to get going." You said to your son, and he ran to his room. Your eyes followed him. Lucifer snaked his arms around you from behind.
"Are you sure you want to leave?" You looked at him.
"It's just for the holiday, but I'll be back after Christmas while Michael is staying for a few extra days. Gabe wants to spend time with his god-son," You turned to Lucifer, displeased with his recent behavior, "Which you've really been denying him lately." Your eyes softened with his, and he dropped his head.
"I know, I know, I'm just worried." You nodded understanding. You wanted to cheer him up.
"On the bright side, that means we have a few days to ourselves." You purred, he put his forehead to yours. You wrapped your arms around is neck, and kissed him. He smiled as you pulled away.
"Just be careful, alright?" He instructed, concern being the only thing in his voice. You smiled.
"Always." You promised. You pulled away and went to grab Michael. He was placing clothes in his suitcase one by one.
"Michael? What're you doing?" You asked, but you knew this would happen!
"Snapping wasn't working. So I started packing like you do, mommy!" He smiled. You faked a smile back, but you were now officially terrified. You helped Michael finish up with his suitcase. Zepar, who had now become a very high ranking demon for helping you, brought you to the bunker. Michael ran to the door, but before he could knock, Castiel zapped behind him.
"CASSIE!" Michael called, hugging Castiel. You laughed as the Angel somewhat awkwardly hugged him back. Castiel opened the door, and led Michael to his room. You shut the door behind them. You hugged Sam and Dean. They laughed. Sam noticed your lack of response. You always laughed when Castiel raced Michael to his room. It was the sweetest thing ever.
"You okay?" Sam asked. You nodded.
"Just tired." You insisted. He nodded, unsure of whether to believe you. The boys had a tree set up, and Gabriel had proofed in a fire place. Well, one to hang stockings on at least. It was Christmas Eve, so you had insisted Michael go to bed early. You laughed and joked with the guys, and caught up. You went to bed around midnight. You woke up to a quite disappointed Michael, saying Santa never came. You knew you put the gifts under the tree, what could've happened? You followed Michael to the tree, as Gabriel came down the chimney, in full Santa get-up. Michael's eyes went wide, and Gabriel spilt gifts in front of him, more than you had brought. You laughed, quite surprised at the amount.
"HO, HO, HO! MERRY CHRISTMAS!" Gabriel said, you laughed at the silly archangel. He climbed back up the chimney. He zapped next to Michael.
"Hey, kiddo! What did I miss?" He asked.
"YOU MISSED SANTA!" Michael exclaimed. Gabriel played it off as if he were upset. You smiled. Later, as Michael opened loads of presents, Gabriel joined you.
"What's wrong?" He asked, as both of you watched Michael.
"Something's wrong with Michael." You explained.
"Why do you say that? Seems fine to me!" Gabriel attempted.
"He isn't aging properly for a nephilim, Gabe. He couldn't even use his powers to pack his suit case yesterday!" You tried. Gabriel shrugged.
"If he's been under stress, he won't age!  The rest was probably just a power surge! Gabriel insisted." You tried to believe him.
"That's not all, Gabriel." He snapped his head to you, he was confused.
"He cut his hand on a glass the other day."
"So?" He shrugged it off.
"Michael honey, can you come here. He rushed to you. You opened up his hand to show Gabriel. His eyes widened as he realized the cut was still there. You sent Michael back to his presents.
"Now do you believe me?" Gabriel nodded.
"Do you know what can do this?" You asked him. He shook his head.
"But I'll ask Dad." He sighed.
"Maybe I should call Chuck. Lucifer has refused to let me this far, but he doesn't know about the cut." Gabriel nodded.
"Good idea." You pulled out your phone, and dialed Chuck's number.
"Hey Chuck! How've you been?" You asked in a worried tone.
Hi y/n. I've been fine, is something wrong?
You fought back tears.
"Actually, yes. There is. You see, uh, how do I put this..."
If it helps the explanation, I know I have a grandson. Gabriel told me.
You nodded. That helped. A lot.
"Yes well, it does. But, um, somethings been happening, and I was hoping you could help me out." Chuck zapped beside you, hanging up the phone. He hugged you, and you hugged back. He pulled away.
"What's up, y/n?" He asked. He looked away from you, and at Michael. You thought he'd see Michael was an abomination. His face grew very confused.
"Wait, I thought it was you and Lucifer's kid?" He asked cautiously. You matched his confusion.
"He is." You confirmed. Chuck thought about it, and looked at you.
"Then how is he human?" Your eyes went wide.
"Human?" You questioned. Chuck nodded, confirming that's what he said.
"That's not possible. He was born last year!" This got more shock out of Chuck.
"Is there anything that could've turned him human?" You begged, hoping for an answer.
"I mean, I could have, but I just found out a couple days ago." He was missing the obvious.
"What about Amara?" You asked. He thought about it for a bit.
"I'm sure she could've, but why would she?" Chuck finally said. This was all too confusing.
"D-Do you want me to change him back?" You thought about it. You'd always wanted Michael to live a normal life, Lucifer had pushed that thought out of your head.
"I don't know. I need to talk this over."
The words he's human echoed in your mind.
