Sherlock walked in to see Eurus sitting on the other side of her glass. She looked up when she heard the door open, a huge smile spreading across her face once she saw Sherlock. "Sherlock! Wonderful to see you again." She said, getting up and hurrying over to the glass. She put her hand against the glass, wishing she could hug her older brother, but sadly not yet. Mycroft said maybe eventually she would be able to, but he doubted it. She didn't blame anyone anyway. If she was in their shoes, she wouldn't let her out either. She only wished to take it all back, and have a few days in the outside world. She was different now, and vowed to never cause harm to anyone ever again, but nobody, except Sherlock apparently, was quick to believe her.

"Hello Eurus. It's good to see you too."

"How is Molly? Is she well? I loved it when you brought her here. I got to apologize in person, and that actually meant a lot to me, so thank you." It took Eurus a while to start talking again, but now that she did; she seemed to be like a child again. She would speak with excitement, and ask several questions at once.

"Molly is well. She actually told me to thank you. If it weren't for you we would have never have actually... gotten together I guess you would say," Sherlock told her.

Eurus smiled, sitting on the floor where she was. "When's the wedding?"

Sherlock's eyes widened slightly at her question. "How did you?"

Eurus giggled. "When I asked about her, you smiled wider than you normally do. Plus, Mummy told me. She didn't mean to naturally, she just couldn't hold in her excitement. All of her children aren't exactly normal, so she was excited that one of her children was doing a normal thing."

Sherlock smirked. "Normal is overrated."

Eurus smiled, but then her face turned more serious. "Will I be invited to the wedding? And do you think they will let me go?"

Sherlock squatted down to be eye level with his sister. "Yes you will be invited, and I'll make sure they let you come. You might have to stay by Mycroft the whole time, but you will come."

Eurus smiled like a child who had been told they were going to Disney World. "Oh thank you Sherlock!" She clasped her hands together with joy, but then, yet again, went serious. "I would like to apologize to John too. I know you told him I was sorry for me, but I would like to tell him myself."

"Maybe I can get him to come here, but I can't promise anything. He doesn't exactly like this place."

"I don't blame him."

.

Sherlock walked into 221B, being greeted by a now four year old Rosie hugging his legs. "Hello Rose," Sherlock said as he picked her up and kissed her cheek. "Where's your daddy?"

"Store," Rosie simply said. "Aunt Molly is cooking!" she said as she pointed to Molly.

Sherlock smiled, going over to her and kissing her. "Eurus said hello," Sherlock told her, putting Rosie down so she could go play. "She wants to apologize to John in person."

Molly looked to Sherlock as if she was uncertain. "Good luck with that Darling. I seriously doubt he will go back to that place."

"Yea, well just in case he doesn't I invited her to the wedding... I hope that was okay."

Molly smiled to him and nodded. "Of course. She's your sister, and honestly the person who got us together... Could have done it in a better way, but she's fine now."

"Daddy!" they heard Rosie shout. Sherlock looked back to see his goddaughter running to her father, and John happily picking her up.

"Hello angel, have you been good today?" John asked, kissing his daughter's forehead.

"Yeth! Aunt Molly and I made wedding invitwations for Nanny, Me-Me Holmes, and Paw-Paw Holmes!" Rosie pointed to where the cards made of different colored paper lay with crayon scribbles on them.

John smiled to the cards. "That's wonderful Rose. I know Aunt Molly and Uncle Sherlock appreciated the help."

"And!" Rosie continued. "Aunt Molly said I can be the fwower girl!"

John chuckled, looking over to the couple whom stood in the kitchen. "That's amazing Rose. Why don't you go ahead and give Nanny her invitation, okay?"

Rosie got excited and clapped her hands in glee. "Otay!" Rosie wiggled out of John's arms, going over to the coffee table and grabbing the purple card.

Sherlock looked to Molly, silently signalling to her that he wished to talk to John alone. "Um, I'll go with her," Molly said and went with Rosie downstairs to Ms. Hudson.

"So," Sherlock said and then cleared his throat. He racked his brain, trying to think of the right way to approach this conversation. "John you are my best friend as you know, and I've asked you to be my best man," he started.

John nodded, sitting down at one of the stools by the kitchen island. "Yes, and?"

Sherlock cleared his throat. "Um, for your wedding gift I got you a new doctor's set if you remember." John nodded, waiting for Sherlock to continue. "And I don't ask much from you when it comes to this, but I have a wedding gift that I wish to have from you."

"Of course Sherlock, anything."

Sherlock took in a deep breath, then let it out. "I want you to come to Sherrinford with me the next time I go."

"Except that," John said and got up, not knowing what to do with himself. "I'm sorry Sherlock, but I will not go back to that place. I'll do anything for you, except that."

"Eurus wishes to apologize to you," Sherlock told.

"No!" John wasn't getting angry, surprisingly. Rather, he seemed frightened by the idea of going back, but refused to show it. "I.. I can't Sherlock. That's like asking me to go back on the battlefield of Afghanistan to remembrance where I got shot."

Sherlock sighed. "John, it's fine now. She's fine now, and she vowed to never do any harm again."

"The woman put me down a well! Better yet chained me to the bottom of a well!"

"I know," Sherlock said. "And that is why she wants to apologize, and for more. Won't you give her the chance?"

John sighed, pinching the bridge of his nose. "I... I finally got over nightmares last year Sherlock... It took me nearly two years to have a proper sleep, and you want me to go back."

Sherlock stood there for a moment before shifting on his feet. "She's coming to the wedding John," Sherlock told him. "I would imagine that she would want to have peace with you before her brother's wedding."

"She will never..." John started but trailed off. "Her brother's wedding..." John gave a long, heavy sigh. "I... You did anything and everything to prevent any chaos at my wedding, even discreetly solved a possible murder... I suppose I should do the same for your wedding."

Sherlock gave a small smile. "Thank you John."

"But," John continued. "We won't stay that long, and this is a one time only thing."

Sherlock nodded. "I wouldn't expect any more."

.

When Sherlock entered into Eurus' room at Sherrinford, just as always, she was ecstatic. "Sherlock!" She said as she practically leaped off her bed. She stopped once she saw John come in behind him. John kept his hands in his pockets, and looked as if he was ready for the ground to swallow him up. "Dr. Watson..." She said, walking the rest of the way to the glass. She smiled to him. "Thank you for coming."

John just nodded. "I'm only here for Sherlock..." he told her.

She nodded. "Thank you... I want to apologize for... everything, especially on the fact of almost taking you away from my brother and your daughter. I've already explained this to Sherlock, but... I was jealous that he had you and I had no one, but that doesn't justify my actions. I don't know what is wrong with me, but I think I am finally over it. I hate everything I did in the past, and if I could I would take it all back, but I sadly can't. I was the woman you texted when your wife was alive, and that alone was very wrong."

John's face dropped at her statement. "You aren't the only one to blame for that one... I was just being a shitty husband." John started to tear up, and he hated that he was. "I loved my wife, and I'm the only one to blame for my actions on that part. I would take it back, naturally, if I could."

Eurus smiled to him. "I'm the one who tempted you, so you are not all to blame. But, the past is the past and we cannot change it. Believe me, I want to go back to when Sherlock and I were children and have a family as I grew up rather than being stuck here. But, the past is how it is for a reason. If I wouldn't have done what I did in the past then Sherlock may have never become a detective. He would have never met you, you would have probably never met Mary... And you wouldn't have Rosie, or anyone else whom you know in your life. Now my actions from three years ago, I couldn't come up with any good from that except the fact that it healed me. It still caused pain on you and others.

"You got me and Molly to realize our feelings for each other," Sherlock commented.

"Okay, so two good things came out of it," Eurus added. "I killed a little boy when I was young and caused so much pain to a family that now it eats me up with gilt... But you are Sherlock's best friend now, and if I can give Sherlock anything, I want to show how sorry I am to you Dr. Watson. I don't expect you to forgive me, I wouldn't. I simply wanted to apologize."

John sighed, finally taking his hands out of his pockets. "You are right, I don't forgive you... But who knows, maybe in time I will." John had no emotion on his, and even Sherlock couldn't guess what he was thinking. "See you at the wedding," John said, turning on his heels and leaving.

. (The wedding is just extra for you all)

The wedding was beautiful, naturally with Molly planning it. Weddings were never Sherlock's thing, but being his own he didn't seem to mind. Eurus had to sit by Mycroft along with two security guards, but they were just happy that she could be there. She was all dressed up, wearing a little white sundress, and having her hair done. Mummy Holmes did her hair, and even John had to admit that she looked lovely.

"Eurus," Molly said as her and Sherlock went to hug her. "You look beautiful."

Eurus smiled. "You can't say that. You are supposed to be the most beautiful here, which you are." Molly had a Cinderella wedding dress, which Eurus thought was the best fitting for her. Eurus then saw John sitting with Rosie. "May I go speak to him?" She asked, pointing to John.

She looked to Mycroft. He sighed, but nodded. "Yes." He looked to the security guards. "She's fine to go on her own, but keep an eye on her."

Eurus smiled to her brother, hugging him. Mycroft was shocked by her affection, but hesitantly hugged her back. She's already hugged Sherlock about twenty time now, it being the first time she could hug him in three years.

She took a deep breath and made her way over to John, sitting next to him before he even saw her. "John..." Eurus said, and John immediately moved to protect Rosie. Not in an alarming way, but in a fatherly way. Eurus nodded in understanding, but smiled to Rosie. "Hello. You are a very pretty girl. You look just like your mother," Eurus told her.

Rosie smiled. "Thank you! But, who are you?"

"I'm your Uncle Sherlock's sister."

Rosie tilted her head, but then her face lit up in realization. "Oh! you must be Euwus!" She said. "Uncle Lock always go see you! You are very pretty like Aunt Molly!"

Eurus smiled more and nodded. "Thank you, and yes he does."

"Rose, why don't you go talk with Me-Me and Paw-Paw," John said.

"Otay Daddy," Rosie said, leaning up and kissing his cheek before going over to Sherlock's parents.

Eurus smiled as she watched her. "She calls my parents Me-Me and Paw-Paw?"

John straightened up, not taking his guard down, but acting more calm. "Yes. She doesn't have grandparents on my nor Mary's side, so they sort of adopted her, as did Ms. Hudson. Though, now they will have an actual grandchild of their own soon."

"Yes, I will actually be an aunt... I just wish I could see him or her on a normal basis..." Eurus sighed, tucking a stray hair behind her ear. "They said maybe in another two years I could actually live in civilization, under surveillance." John slightly frowned at this. "Don't worry, that's all behind me now. I promise I'm not violent anymore and that I am good... Since my brother is practically the British government, they are giving me a chance... I just have to wait two years. Today is sort of a test run to prove that I'm fine." John nodded, not knowing what else to say. "I have to live with someone to guard me though. Sherlock offered for me to take your old room, or if they move to live with them... Molly doesn't mind."

John took in a deep breath. "Eurus..." he was going to say something along the scale of 'maybe we can be friends down the road' to 'piss off', but decided against both, wanting to be civil for Sherlock and actually give her a chance. He gave out a puff of air before speaking. "You look lovely."
