Author's Note: I'm not entirely sure if I like this chapter, but I hope somebody does lol

A chill crawled up Molly's spine as she followed Sherlock through the halls of Sherrinford. It was a dismal place that would cause anyone of perfect sanity to go crazy. She thought of how lonely Eurus must have felt when their Uncle Rudy placed her here as a little girl. Having been told that the youngest Holmes did not exhibit emotions, Molly still wondered if she had cried herself to sleep on some nights.

"Let me go in first and prepare her for your visit," Sherlock instructed her. He noted a look of uncertainty on her face. "Are you still positive you want to do this?" Molly nodded, giving him a small smile. He pressed his lips to her forehead and stepped inside. She waited patiently, listening intently to the melodic sound of the Holmes's violins. It wasn't long before Sherlock came back for her, guiding her inside, finally coming face to face with Eurus Holmes.

"Oh, she's lovely," Molly remarked quietly. "The two of you look so alike." One corner of his lips tugged into a half smile at his fiancée's comment. "Does she mind if I speak to her?"

"No, it's alright. She doesn't talk at all anymore, but she'll listen to you," Sherlock replied.

"Hello Eurus," Molly smiled, attempting a cheerful approach. "I'm Molly. I brought you a gift." For once, Eurus's stare wasn't vacant, but her eyes hinted at curiosity. He took the small box from her hands and placed it in the airlock for her. Eurus hesitantly lifted the box out and opened it. They watched as she lifted the necklace out by its chain, inspecting it every which way. It was a silver outline of a heart with the words 'big sis' engraved on it.

"Sister?" Eurus asked, leaving them to be shocked at her voice sounding out for the first time in months.

"Sister," Molly confirmed, lifting up her own matching necklace. Hers was a smaller heart that had 'little sis' engraved on it. The size of hers was meant to fit right in the empty space of Eurus's. She pointed at Molly's left hand, the ring glittering where the lights hit it. If they blinked, they would've missed it, but a ghost of smile appeared on her face for just a split second.

"Sisters," Sherlock smiled at them both.

When New Year's Eve arrived, Molly had 221B decorated in shades of black, silver and gold. She hadn't planned on hosting a party, but Sherlock knew she wanted to and told her he would be fine with it, her argument being that it would make him feel uncomfortable. After his obvious enjoyment of Christmas, she supposed he was more comfortable with this than she assumed.

John, Mary, Rosie, Mrs. Hudson, Meena and Greg were all in attendance. Molly wanted to take the opportunity to introduce the latter two to each other in hopes something good would come out of it for both of them. She looked around for Sherlock, wondering where he had gone off to now. Their bedroom door was cracked open and she approached it, hearing him talk on the phone.

"Mycroft, where are you?" Sherlock asked. "Molly really wanted you to be here tonight. Do not break her heart." With that, he hung up and tossed his phone onto the bed.

"Sherlock?" Molly called to him, entering their room. "Everything okay?"

"I'm sorry, darling, but it seems that my brother may not show up," he told her, running a hand through his hair.

"It's alright; he doesn't have to come," she assured him. "It's probably too overwhelming for him." Sherlock pressed his lips to hers tenderly. He knew that Molly wanted him to have the same sense of family that she had before her parents passed away, but there was nothing he could do to make Mycroft cooperate. After all, his brother was her family too and he felt that she still held a deep sadness over the fact she didn't have hers anymore.

"You'll always have me," he whispered without realizing he had spoken out loud. She only held onto him tighter before letting go and stepping back out into the sitting room with him. They mingled with their friends and were dancing when the door to 221B opened.

"I hope we aren't late," Mycroft announced, Anthea by his side. "I heard there'd be biscuits." This received a laugh from them all. Sherlock watched as Molly instantly went into hostess mode.

"There's chocolate chip, snickerdoodles and ginger nuts," she told him, leading him into the kitchen happily. Mycroft had to admit, the party wasn't as bad as he expected it to be. He did know everyone there and even the teasing from Sherlock was down to a minimum. In fact, they were actually getting along. Molly had a knack for bringing people together in unimaginable ways.

Ten, nine, eight, seven, six, five, four, three, two, one, Happy New Year! Sherlock snogged her thoroughly not caring at all that they were in the presence of others who were doing the same with their loved ones. Everyone took turns, peppering Rosie's face with kisses, making her giggle. It was definitely the best New Year's Molly ever had.
