A/N GIF above is how I imagine Sherlock looks when he sees Macy for the first time.

Macy knocked sternly on the door and waited impatiently the 54 seconds it took for it to open and reveal a short woman.

Macy's look ran up and down her legs, noticing every part worth seeing.

She'd only just gotten home. A light lipgloss and a piece of white fur from a cat that most certainly didn't belong to her, along with the obvious folds from her having worn a coat not long ago.

"You're here for Sherlock Holmes and John Watson?" She asked. I nodded while scanning my mind for information on this 'John Watson'.

I remembered his name being on an article about my dad. That's where I recognised the name from, he worked with my father!

"They're right up here," she said while leading the way up a worn out staircase.

"Sherlock!" she yelled as she opened the door, allowing Macy to enter behind her.

"Not now, mrs Hudson," Sherlock complained as she entered.

Macy quickly scanned the people in there.

Man number 1: tall, long nose, dark, curly hair, grey eyes like her own. She looked at his features and realised that this man was Sherlock Holmes; her father.

She lost interest for the other two men in the room and studied the man before her.

"Sherlock, it's a client," Mrs. Hudson, as her name was, told.

"Actually, I'm not a client," Macy corrected; "I'm Macy." Sherlock's entire body stiffened for a second before turning slowly around. His eyes ran over her face quickly, desperate for answers.

"Penrose?" he asked baffled.

"Hello, dad."

"DAD?" the two men yelled in unison.

"Sherlock, what the hell does 'dad' mean?" the man, who clearly showed some kind of affection towards Sherlock asked.

"What are you doing here, Penrose?" he asked annoyed.

"Mother send me," she explained.

"Why?"

"She needed someone to take care of me," Macy replied.

"I clearly stated I had no interest in you being part of my life," Sherlock informed.

"I know. Mother's dead." Sherlock's eyes sought his daughters to look for signs.

"I'm not lying," Macy stated; "I can see it. You're trying to deduce me. Go ahead. Look at my eyes. Flickering? Any reaction from the pupil? Body language. Look at my arms. Look at my stand." Sherlock followed the girls orders.

"I'm not lying, and you know it. But you are. What are you lying about?" she asked and took a step closer, getting caught up in her deductions.

"Oh! It's something about John Watson! No no, that's not it, you're not lying. Look me in the eyes!" she ordered.

"Oh. It's me. I'm the secret," she realised.

"STOP DEDUCTING ME!" Sherlock yelled, both hands flying towards his head where they covered his ears. He removed them slowly, looking at his daughter with rising interest.

"You thought that would impress me," he stated; "Well, it didn't. I want you out of here. Leave."

"Sherlock," John intervened.

Sherlock Holmes looked at his best friend.

"John, she's-""She's your daughter, that's it. If nothing else, you can at least let her stay the night," John interrupted.

"She can't stay the night!" Sherlock complained.

"She's staying, and that's that!"

"Anyone care to explain what the hell is going on?" the third man asked frustrated.

"So oblivious," Sherlock cried as he let his body fall into the old-looking chair.

"He's my father," Macy stated.

"No, she's my daughter!" Sherlock corrected.

"What difference does that make?" John asked and sighed deeply.

"He's trying to show dominance. Not very well, considering his current state," Macy explained.

"And what state would that be?" Sherlock asked unimpressed.

"I know something you don't. And, it's obvious that Johnny Boy wo-""Don't call him that," Sherlock warned. Macy rolled her eyes.

"It's obvious that John is going to let me stay the night, so thank you for castrating him," Macy said, turned to John.

"John doesn't make my decisions," Sherlock argued offended. Macy gritted her teeth; "Doesn't he?"

"Besides, based on your pupil dilation an-""STOP DEDUCING ME!" Sherlock yelled. He turned to John, who hadn't seen his best friend like this before.

"Have her gone before I'm back," he warned before storming out the door.

"Sherlock!" John yelled annoyed after him.

"I'm sorry," Macy apologised looking to her feet.

"Sit down," John ordered. Macy sat down in what she would later find out was her fathers chair.

"So, who are you?" the third (well, by then second) guy asked.

"Macy. Macy," she repeated.

"Nice to meet you, Macy. I'm inspector Greg Lestrade, a... Colleague, of your fathers," Mr Lestrade decided.

"And what Sherlock, what your... Father, called you..?" mr Watson asked.

"Penrose is a middle name. Just like Sherlock. Uncle says it's a family thing, going by your middle name," she explained politely.

"Sherlock's his middle name?" Greg asked surprised.

"Yeah. I did some research, his first name is William. William Sherlock Scott Holmes. I figured you'd know that. You're friends," Macy stated.

"William," mr Lestrade said with a short laugh.

"And your full name?" John asked and sat down in the chair across from Sherlocks.

"Macy Penrose West Holmes," Macy replied obediently.

"And you're Sherlock's daughter?" mr. Lestrade checked again.

"Yes. I really am sorry if I intruded, mr. Watson," Macy apologised again.

"It's quite alright, Penrose," mr Watson promised.

"Macy. It's Macy, actually, mr Watson," she replied quickly. John smiled.

"Call me John, Macy."

"No way, the wife obviously did it!" Macy argued with a laugh.

"Obviously!? It took us three days to figure that out!" Greg told her.

"Oh come on, that's just bloody pathetic!" Macy cried out. Greg shrugged.

"Can't all be the daughters of geniuses."

"I'm not," she quickly replied. John looked confused at her.

"I just mean, there's no technical definition of a 'genius' so it goes by personal definition, meaning that... Doesn't matter," she decided and waved it off.

"What happened to your mother?" John asked suddenly.

"She died," Macy stated.

"When?" John asked. Macy looked at her wristwatch.

"I'm guessing a couple of hours," she shrugged it of.

"How can you not know?" Greg questioned.

"I left last night. Uncle promised he'd let me know after it happened, so I'm guessing he'll come by eventually to inform me of the news," she guessed.

"Your mum's brother?" John asked from his seat on the dining chair he'd moved to the living room so he could sit next to Greg and Macy.

"No, my mother had no siblings. My father has a brother, however," she explained. John narrowed his eyebrows; "Wait, Mycroft? Mycroft knew about you?"

"Yes, Uncle knew," Macy replied.

"Anyway, it's getting late and I should get going," Greg decided after a minutes awkward silence.

"If you ever need a job or commit a murder, you just call me," Greg mentioned to Macy, who grinned thankfully.

"Thanks Greg, I'll remember to mention your name when I commit to my murders," she promised. He looked up.

"Maybe just don't get caught!" he decided; "See ya John!"

Macy's smile faded as she watched Greg, the guy who without doubt had been the nicest to her so far, walked out the door. Shortly after she could hear the front door smack behind him.

"I should get going as well," she mentioned and stood up before brushing off her shirt.

"Where are you staying?" John asked before getting up himself.

"I'm, um, not quite sure yet," Macy admitted embarrassed.

"Right, you're staying here," he stated.

"Oh, no, I don't wanna cause any more problems, I can figure something out," she assured him.

"How old are you, Macy?" John questioned.

"18... In a year... And three months. Listen, all I need is for my dad to sign some papers so I can get an apartment for myself. As soon as I turn legal he won't have to hear from me ever again," she promised; "I already have the papers, I just need the signature."

Macy stuck her hand into her pocket and pulled out a folded piece of paper.

"Let me see that," John asked. He received the papers handed from Macy and looked through them.

"You need to be 17 for this to even be an option. You're only 16, where will you stay until then?" he asked and handed back the papers.

"Oh don't worry, Uncle promised I could store my things at his for the three months, I'll just live on the streets, it's not a problem," she assured him, brushing the entire thing away.

"What? That's your plan? Staying on the street? Wouldn't Mycroft let you stay with him?" John suggested, barely listening to Macy's explanation as to why that wasn't possible.

"I'll talk to Sher-your father. But you're staying for the night at least, you can take my room," John offered.

"Bu-""No buts!"

John had shown Macy to his room, and after having sighed of her thoughtlessness of not having brought anything, borrowed her a shirt and some sweatpants that was too small for him, but would hopefully fit her better.

He'd allowed her to get changed and into bed in privacy while preparing the couch for himself, but hadn't been able to resist the urge to check in on her, making sure she wasn't taking too much after her father, who'd ran out on John plenty on times.

But after having ensured Macy was still there and asleep, he could let himself fall asleep on the couch.

"JOHN, SHE IS NOT STAYING HERE!"

"SHE IS YOUR DAUGHTER!"

Macy rubbed her eyes.

"NO, SHE'S NOT. SHE'S HER DAUGHTER."

She was used to birds screaming in the morning. Not the father who abandoned her as a child and the man she was fairly certain he was being gay with.

"HER MUM'S DEAD AND SHE'S ABOUT TO END UP ON THE STREETS! YOU'RE HER FATHER, SHERLOCK! GET YOUR ACT TOGETHER."

Macy slowly crawled out of bed and neared the door in her borrowed bedroom.

"Sherlock, you can't possibly be serious," she heard John argue through the door.

"She looks like her! I can't have her walking around in my flat while I'm working," Sherlock's voice complained.

"Sherlock she looks exactly like a female you," John pointed out.

"Fine. She can stay. For now," he added.

"It's only three months. Cheer up," John said cheerfully.

"THREE MONTHS? Oh no, she's got a week. That should be enough time to figure out somewhere to stay."

The voices lowered, and Macy realised she'd been eavesdropping. She rubbed her eyes a second time before slowly opening the door, which led straight to the living room.

"Morning, Macy," John greeted calmly.

"Goodmorning, John. Goodmorning, Sherlock," Macy replied politely.

"Sherlock, do you have anything to say back?" John asked from the kitchen. Macy looked at Sherlock who was sitting, already in suit, in his chair, and had a newspaper in front of his face. He sighed deeply before letting it down.

"Good morni-Oh, you have got to be kidding me!" he cried out.

"What's wrong?" John asked, his head appearing above a flower patterned apron in the living room.

"She's wearing your - you're wearing his clothes!" Sherlock complained to her. Macy looked down herself. She was still covered by the t-shirt and sweatpants she'd borrowed.

"Take that off! Right now!" he ordered.

"What? Why?" John asked offended.

"She's wearing! It's! That's yours! She can't wear that!" he complained, disgust clearly shown on his face.

"Fine. Macy, maybe you should just go get dressed," John suggested before sending her an apologising look.
