"Y/N, you can't stay here in New York. It's too dangerous." Your husband, Stephen Strange said. "And I don't want to risk losing you, or one of our kids" he said.

You embraced him. "Alright then, sorcerer supreme. Where will we go?" You asked him.

" Well...when I became sorcerer supreme, I built a house out in the country, away from everything and everyone. I call it our 'safehouse' " he said.

You smiled. "Of course. When will we move in?" You asked.

" ASAP. " he said. "And the kids? How do we tell them?" . He thought for a moment. "Tell them it's an adventure" he said.

You nodded. "Alright then. But be careful, Mr. Doctor" you teased. He laughed and then kissed you softly.

"Tony...I'm s-sorry. It was the only way..." Stephen said as he approached the once happy man.

" But...why? Why Strange? Why a boy? " he asked, shaking as sobs wracked his body. "Why my son?" He whispered .

Stephen shook his head and placed a hand on the broken man's shoulder. "I don't know, Tony. But right now, I think we have to get going" he said.

Stephen opened a portal in Wakanda and found another group of people huddling together.

Both groups stared at each other in shock. It has been three years since they had had any contact, and now, they were reunited.

Everyone felt the tension as Tony and Steve stepped forward. They held their breaths, but were surprised when they embraced.

Soon, they were all talking silently as they thought of what to do next.

Stephen stood in silence as he debated if he should mention the safe house or not. The whole point of building it had been to protect you and your children, not put you in immediate danger.

He rubbed his temples and then took out a picture of the family. It was you, him, your oldest son Samuel, your second son Andrew, your daughter Sarah, and your youngest, Bethany.

He smiled as he looked at the picture, then looked up. He sighed and walked up to the group.

"I have an idea. I know a place...a safe house we can go to" he said as he approached them. Everyone stood in silence.

"Are you sure that's it safe?" Tony asked. Stephen nodded "I made sure that it was" Stephen said.

They all nodded. "Alright then. What are we waiting for?" Steve asked.

" Follow me" Stephen said as he opened a portal. He waited until everyone went through and then looked up.

They were in the country, on a ranch. The huge house standing before them was beautiful, and it seemed more like a dream mansion than a house on a ranch.

"Wow" Tony said as he looked at his surroundings. "Who built it?" He asked. "I did, with the help of some friends" Stephen said, looking at Bruce and Natasha.

Tony nodded as they followed Stephen in. You heard the door open and you looked up from your cooking.

"Babe? I'm home!" You heard Stephen say, and you walked out. Your relieved smile turned into awe as you saw all the heroes that were standing in your living room.

They all looked at you a bit strangely as you and Stephen embraced. He kissed you long and deep, your pregnant belly between you.

As he was kissing you, you felt the baby stir and Stephen smiled. He placed his hands on your stomach and said "It appears that you're not the only happy one" he joked.

Then, he turned to the rest of the heroes. "Guys, and girls, I want you to meet my beautiful wife, Y/N" he said.

They all waved awkwardly. Suddenly, footsteps could be heard, and three children ran in.

"Papa!" They yelled, hugging Stephen. " Oh, my children! Look how you've grown! " he said as he hugged each of them. Suddenly, his smile faded.

"Wait, where's your brother?" He asked. Suddenly, a boy using crutches entered the room. "Dad!" He said. "Andrew!" He said, his shaking hands picking him up with ease.

Everyone stared at your happy family, not believing their eyes. Steve was the first to talk "Well...Um, we are sorry to intrude, and I want to thank you for letting us stay here" he said.

At the sound of his voice, your kids all turned and looked at the heroes in awe. "Y-you're the Avengers?" Samuel asked, barely containing his excitement .

Steve nodded and your kids smiled wide. "Dad, did you bring Uncle Bruce?" Andrew asked. "And Auntie Nat?" Sarah and Bethany asked.

Both Bruce and Natasha walked forward and said "Why don't you come hug us and see?" . Stephen handed Andrew over to Bruce while Natasha picked up Bethany and hugged Sarah. Samuel went over and hugged Bruce.

"You two knew about this?" Tony asked. Before they could respond, Stephen interjected. " They did, but promised to keep it a secret" he said, giving no further explanation.

Tony nodded, not pressing the matter further, which was new for him.

"Well, if you don't mind, I'm going to step outside for a while" Tony said. "Me too" Steve said. Soon, most of the heroes had gone outside.

Stephen walked up the stairs to your bedroom. He began to change, and you walked in as he was going to put on his shirt.

"Stephen, wait" you said. He put the shirt down and asked "What's wrong?" . You touched his side, and he winced. "That looks pretty bad" you said. "It's nothing" he answered.

"Are you sure?" You asked. He nodded. " I'm fine. Don't worry. " he said.

" Stephen, I love you" you said as you hugged him. He hugged you back, then tilted your head up and kissed you softly. "Oh, Y/N, you're so beautiful" he said. You blushed.

"I'll go finish dinner" you said as you pulled away from him. He nodded, looking a bit disappointed, but instead opened a portal.

"Stephen, I can walk, you know?" You said. He laughed " I know, but I still care about you and your health" he said.

You shook your head "Go on outside, Samuel is waiting for you" you said.

He walked outside and you looked out the window. He and your son Samuel started to pass a soccer ball around, and soon Cap and Thor had joined in.

"How do we do this again?" Thor asked. "You just kick it" Samuel said. "Ah" Thor said.

Andrew was sitting on the porch, his crutches leaning on the wall behind him. He was working on some sort of gadget, and was getting frustrated over it, something your little boy rarely did.

"Need some help kiddo?" Bruce asked, walking over and sitting next to him. Andrew nodded. " I don't know how to get this to work, and it's really annoying " he said.

Bruce picked up the gadget and began to fiddle with it. "Hmmm" he said as he moved wires and unscrewed things.

Tony walked by, and noticing the pair struggling, headed towards them.

"Need help fixing your toy?" Tony asked. Andrew turned to him "    It's not a toy, but yeah. We need help" he said.

"Let me see" Tony said as he took the gadget from Bruce. "Where did you get this?" Tony asked as he began to fiddle with it. " I...I made it" Andrew answered.

Tony froze. "You made this?" He asked in disbelief. Andrew nodded sheepishly. "Yeah" he said.

"Jesus, boy! How can someone your age know what even a part of this is? Much less make this!" Tony exclaimed. "You're a genius!" He said.

Andrew smiled from ear to ear. "No I'm not..." He began. " Yes you are son, don't let anyone tell you otherwise" Tony said.

"But, what about..." He said, his voice trailing off as he motioned to his legs and crutches.

"People think you're not smart because you have a disability?" Tony asked.

"Yeah. I tell them that I have Spastic Cerebral Palsy, they search it up, and then they treat me like I'm retarded" Andrew said bitterly.

"Listen to me, Andrew. You are not retarded. Your disability is nothing to be ashamed of. And don't let people tell you that you're not a genius, because you have a very brilliant mind" Tony said.

"It's true, Andrew. Be yourself, and don't let those bullies bring you down, alright son?" Said Bruce.

Andrew nodded. "Thank you" he said. "Both of you"

Both men nodded. "Now, let's see how we can fix this, shall we?" Tony said as all three of them began to work on the gadget.

During dinner, the weight that had been floating around them seemed to lift.

The table was full of laughter, and their worries were temporarily forgotten.

When the time came to go to bed, you and Stephen retired to your bedroom.
You lay in bed, Stephen holding you in his arms.

"I'm worried, Stephen. What if you get  killed this time?" You said, looking into his eyes.

"Hey, listen. Everything's going to be alright, ok? No one's going to get hurt" he said, kissing your forehead.

You smiled. "Ok" you said, as he leaned down and kissed you.

That night, you fell asleep in your husband's arms, feeling safe in his embrace.

Two years later

"Dada!" Your youngest son, Zachary said as he outstretched his tiny hands towards Stephen.

He picked Zach up with a smile as you bounced Zachary's twin, Andrea.

Everything had turned out alright, just like Stephen had said.

Tonight was Christmas Eve, and everyone was at your house, now known as "the safehouse".

As everyone laughed at the Christmas stories around the fireplace and the snow fell outside, you smiled.

It had been a good idea to build the safehouse, and now, here you were, together, as a family. 

Stephen kissed you softly as both of you sat down with the rest around the family.

Andrew came running in, no longer needing his crutches. He had been a miracle case, and he could walk like a normal boy.

He smiled wide and said "Merry Christmas! And blessings to all!"

And everyone cheered as smiles lit up their faces, for peace had come at last.
