Reader POV

I hear Mycroft and I's son crying, so I flop out of bed and rush into his room. He is 3 years old, and a hug Mama's boy.

"Hey, baby. What's wrong?" I ask, sitting on his bed, pulling him into my lap. "I want Daddy!" He cries. "Daddy is sleeping. Can you tell me?" I ask, not wanting to wake up Mycroft.

"It's about something only Daddy knows!" William cries. "Okay, Will. I'll go get Daddy." I say, putting him back on his bed.

I walk into Mycroft and I's room and sigh. "Mycroft." I whisper, shaking him slightly. "Hm?" He grumbles. "Will needs you. He refused to talk to me. He said it's only something you know." I say, tears in my eyes. I am scared for my little boy.

Mycroft gets up and rushes into Will's room, shutting Will's door. I wait for about half an hour to go in and see what is wrong. When I walk in. Mycroft is laying in Will's bed, Will cuddled up to him, both of them asleep.

"My Holmes boys." I whisper, covering them with a blanket. Will stirs a bit, but then he stops moving and relaxes. I walk back into my room, and see a man. "Who are you?"  I ask, my voice trembling.

"The name is Sherlock Holmes." He says. "Sherlock! What the hell are you doing here!" I whisper yell. "Well, what your son knows is something very very serious and I think it requires you and your son to leave this house and Mycroft." He says, smirking.

"What is wrong? Why do I need to leave my husband?" I ask, tears streaming down my face. "Mycroft is having an affair." Sherlock bluntly says. He hands me Mycroft's phone and I see the messages. They are awful and so dirty. 

I rush to Will's room and quietly pack him a bag. I remove my son from his bed carefully, not wanting to wake him up. I go back into my room and see Sherlock already has a bag for me. I write a note to Mycroft saying,

'Whoever the other person is, I hope it was worth loosing your son and your wife.

                                                         Y/N Moriarty '

I walk out with Sherlock, my son sleeping on my shoulder. We walk to my car and I strap my son into his seat. He wakes up and looks around, smiling.

"Mama, you found out?" He asks, smiling. "Yes, why are you smiling, love?" I ask, confused. "Daddy yelled at me when I found them kissing and I realized Daddy is mean and I want Mama happy." He says.

Sherlock smirks as we drive away from Mycroft and his lies.

=============================11 months later======================================

Will and I have been living happily with John Watson, my fiance. Mycroft and I are completely divorced, with me getting full custody. Mycroft can only see his son on Easter and his birthday. Mycroft has apologized about 500 times, and each time I say no.

Will hates Easter because he has to spend a full week with Mycroft. I tell Will that if his father yells or hurts him in any way, to tell me immediately.

On Will's fourth birthday, Mycroft came to Sherlock's flat and just dropped off a gift for his son. His birthday was months ago and none of us has opened it. 

Today is my 28th birthday and I couldn't be happier. I have my little boy in my lap, and John at my side. Will loves John and John loves Will. Will started calling John, Dad, which has to be the cutest thing ever.

John has his daughter, Rosie, who is 2 now. Mary passed away, which was hard for John, but he fell in love again.

Rosie has called Mama more than I can count, mainly because she wasn't old enough to remember Mary. We hear a knock at the door, and there stand Mycroft. Rosie walks over and smiles. I pick her up and place her in my chair.

I walk back up to the door and shut it behind me, so I can talk to Mycroft. "What the hell do you want?" I ask, annoyed.

"You and William back. I really really messed up and I cannot live without you two. You two are my life. I love you, Y/N. I love Will too. I want you both back." He says,crying.

" I'm sorry Mycroft, but no. John gives me everything I have ever wanted. I have more than one child now. I have a daughter who needs me." I say, sighing.

"Rosie is not your daughter." He says, scoffing. I walk in and grab the adoption paper, that John and I framed. I walk back out and show him.

"She is my daughter. Now if you'll excuse me, I have to go tell my family the good news. Good day, Mycroft Holmes." I say, slamming the door shut.

I walk into the flat and smile.

"John, it's happening." I say, smiling. John looks at me, his eyes wide. "What is happening?" He asks, confused.

"We are completing our family with two more little ones." I say, grabbing my purse and handing John the ultrasound photos. "12 weeks?" He says, crying.

Will and Rosie walk up to us. "Mama, Daddy, what's wrong?" Will asks. John picks up Will and I pick up Rosie. "Honey, we are having twin babies! In about 7 months, you will be a big brother, Will. And Rosie, you'll be a big sister!"

Will hugs John and Rosie hugs me. Then, we all get in for a group hug.

Our little family of 4 is becoming a family of 6!
