Hello all! Finally updated. I hope to have more up soon but Saturday is my birthday (turning 25! ahh!) and I have a busy weekend so it may not be right away. This chapter has Mycroft in it, for the guest who requested more Mycroft. I am planning on working him in more because who doesn't want Mycroft with an adorable baby sister? Thanks, as always, for the reviews/favs/follows! You guys really make my day! Here's chapter 13!

Chapter 13

There was a loud 'bang' as the door to 221B was flung open. Hasty footsteps were heard racing up the stairs and soon Mycroft Holmes stood in the doorway out of breath, his eyes wide and panicked. His head flew from side to side as he frantically searched the room. His eyes landed on his two siblings resting in Sherlock's armchair, the younger one clutching Sherlock's scarf in one hand and her thumb stuck securely in her mouth.

She looked absolutely terrified but relatively unharmed. Mycroft let out a huge sigh and sank onto the couch. He closed his eyes and put his head in his hands, not yet ready to speak.

"You ran up those stairs pretty fast, brother. I assume your diet plan is paying off?" Sherlock said.

Mycroft didn't dignify his question with an answer. He was still staring at Addie as if she was going to disappear right on the spot.

"She hasn't sucked her thumb in years. Well, I mean, at this age she hadn't," Mycroft observed.

"Yes, well I tried to remove it many times and all I got were tears and frowns. I've just let it go. Plus she has been through a rather terrifying experience, so I think we can let it slide this time," Sherlock said.

Mycroft nodded. He scooted closer to them and leaned in a bit to face them. He held out his hands tentatively, not sure how Addie would react.

"Can I…?" he asked, gesturing to her.

"You can try, but she hasn't let go of me for over an hour and a half," Sherlock said as he fondly ran his hand up and down her back. "But if you could get her to let go, that would be great. I could really use a break."

Mycroft approached carefully and reached for her as Sherlock gently extracted her hand from his scarf and started to transfer her to Mycroft's waiting arms.

Addie let out a small whimper and a panicked, "NO!" She clutched to the end of Sherlock's coat and held it tightly like a lifeline.

"Addie, I need you to let got for a bit. Mycroft's here and he's going to stay with you. I'll be right back. I'm just going to the loo."

Addie's eyes welled up and she looked at him with imploring eyes. "Mykie?" she asked shyly.

"Yes, Mykie's here. He's right here so you can let go and sit with him for a few, alright?" Sherlock asked.

"Kay," she said as she allowed herself to be transferred from one brother to the other and Sherlock left the room.

Once she was in Mycroft's arms she squeezed him tight and burrowed into his chest. Her thumb found its way back into her mouth and she closed her eyes, resting against her oldest brother. Mycroft clutched her just as tightly and buried his face in her hair as if needing reassurance that she was really there. He saw the story on the news, a horrible way to find out anything, and he rushed over immediately. He was frustrated that he wasn't informed sooner, but he reasoned that Addie was the first priority and informing him wasn't exactly everyone's first thought.

"Mykie….I'm scared," she murmured quietly.

"I know, love, but you're alright now. You're safe and nothing bad is going to happen to you," He whispered in her ear before giving her a kiss on her bruised forehead.

"My head hurts. Real bad," she told him, rubbing her head and grimacing.

"We'll be sure to get you some pain relievers. Maybe John can run to the local market and pick some up," Mycroft suggested. "Where is John anyways?" he asked, noticing the absence of the doctor.

"He went to the hospital to talk to Mr. An'erson and see if his 'cussion is better," she said.

"Mr. Anderson?" Mycroft asked.

"Detective Anderson," Sherlock said, entering the room. "He's the one that saved her. Got himself a nasty blow to the head."

"Detective Anderson? As in the one who's always giving you sh-, uh, trouble?" Mycroft asked, shocked.

"That would be the one. The one and only," Sherlock said with a curl of his lip.

"Well then, I shall have to go and give him my thanks and appreciation," Mycroft said.

Sherlock looked away and gave a long-suffering sigh.

"You should do the same Sherlock," Mycroft told him. He gave him his signature raised eyebrow and "big brother look."

"Yes, Yes, I know. Can't I just get a day or two? I need to process everything! My mind is going crazy!" he answered.

Mycroft looked sympathetic and nodded in understanding.

"I'll text John to tell him you're coming over. And to pick up some kids pain reliever for Addie," said Sherlock. "Shall I tell him you're on your way?"

"No. No rush. I think I'll sit here for a bit longer if you don't mind," he said as he rested his chin on Addie's head.

Sherlock almost smiled at his horribly sentimental brother, but instead rose to walk to the kitchen.

"Tea?" he asked.

"Please. Something strong to calm the nerves," Mycroft added.

Sherlock now allowed a small smile to grace his lips as he made himself and Mycroft the strongest tea in his kitchen.

John came home a half hour later and Mycroft took his leave to go see Anderson at the hospital. Addie was clingy with Mycroft and was unwilling to let him leave. They finally convinced her to let him go and he parted with a kiss on her cheek and a promise to come by later in the week.

John made Addie lunch and gave her the medicine he picked up from the market. Addie took it without fuss, which was testament to how much her head was hurting her. She continued to attach herself to Sherlock's hip and followed him everywhere. When he checked his website, she was sitting at his feet and clinging to his leg. When he was experimenting she was right by his side watching him work. When he was laying on the couch thinking, she was curled up next to him resting her head on his chest.

This went on for a few days and eventually Sherlock had to leave for a bit to go down to Scotland Yard and talk to Lestrade about a case. Addie then attached herself to John. He didn't mind her acting as his shadow. John was frankly quite glad to have her in sight. The bus incident had shaken him up as well. He was sitting in his armchair reading the paper and Addie was on his lap "reading" it too. She started to rub her head and squint. John noticed this and gave her more pain reliever. When she was finally feeling better, Addie got off his lap and started drawing in her journal.

"How do you spell grateful, Mr. John?"

"G-R-A-T-E-F-U-L," John answered.

"How do you spell sakerfice?"

"Sacrifice," he corrected, "and it's spelled S-A-C-R-I-F-I-C-E."

"Thanks."

"Addie, what are you doing?" John asked curiously.

"I'm writing a note to Mr. An'erson to say thank you for saving me from the bus. Sherlock said we're gonna go see him when he gets back," she told him.

"That's very thoughtful of you Addie," John said with a smile.

"Mr. John, is his 'cussion better?" Addie asked with genuine concern.

"His concussion is much better Addie. He's not in the hospital anymore either, he got to go home a few days ago. He should be back at work by now," John said.

"That's good, right?" she asked

"Yes, very good," John answered.

Sherlock came through the door then and started getting Addie ready to go. Addie had John pull her paper out of the notebook so it wouldn't tear and she slipped on her boots.

"Sherlock, Mr. John said Mr. An'erson is back at work. Are we gonna go see him at Cotton Yard?"

John chuckled and even Sherlock couldn't hide a smile. "Yes, Addie. We're going to go visit Scotland Yard. Let's go get a cab."

"Ok. Is Mr. John coming?"

"No, Mr. John's going to stay here. We won't be long."

Addie waved goodbye to John and followed Sherlock out to the cab.
