When Sherlock was 13, he became fully independent from needing anyone's permission or approval. He left the house when he wanted or needed, he got home when he wanted or needed. He had access to the cars and was fully capable of walking himself to town. He didn't need help or anything; he lost his lisp so he was more confident in what he did. By now, Sherlock became happier.

Then, he became invisible. Partly or purpose, partly on accident. The purpose part was at school. He didn't like to be noticed. He had no friends, he didn't then have any enemies. With that, he was fine.

On accident he became invisible to his mother and Mycroft. Mycroft was almost 20 by now, long time moved out of the house and on his own. Sherlock didn't see him much. But his mother, she didn't show him as much attention as she used to. He wasn't a baby anymore, she knew that. She couldn't baby or smother him. She let him do as he pleased and didn't stop him.

For the most part, Sherlock liked that.

Then, he wanted to conduct a small experiment to see just how invisible he really was. He began at school. Until now, Sherlock wasn't into fashion at all. He always wore regular, long sleeve t-shirts, jeans, and scarves. He didn't care all that much, with his disheveled hair he usually looked like a kid that didn't live in a giant house in the richer parts of town.

His first experiment was a clothing test. He pulled out the shirt his mother got him to wear for Christmas last year that he refused to wear. It was a deep purple button up that was probably 10,000 thread cotton. He thought it was ill fitting, a little too tight, but there was a man in a magazine he found in his mother's room that was wearing a shirt just like it and that ill fitting. So he slipped it over his shoulders and slowly buttoned it.

"This is absurd," he muttered to himself, "I look ridiculous." He buttoned his shirt to his neck, then unbuttoned the top two. "Really? My neck exposed for attack?" he nodded at himself in the mirror and brushed his hair down. He put his coat on and left.

Multiple kids at school noticed, mostly girls. A few girls stared at him and his exposed neck all day. One girl, at the end of the day, told him he looked very nice and she liked she change. Sherlock half smiled at himself, but what really got his blood pumping and his forehead glistening with nervous sweat was when a boy from the grade above him, named Jack, shoved him into the lockers and kissed him. The boy quickly left, obviously embarrassed, but Sherlock stood catching his breath and smiling wide.

Obviously a good change. Sherlock had a new love for soft button ups.

The next experiment he decided to conduct was at home. It was a bigger, more drastic change, so Sherlock let it slide in gradually. It was light at first, he left the bleach in his hair for only a few minutes. It was an obvious lighter brown to him, but someone would have to be really be staring at him to notice.

One person noticed: Jack.

"What'd you do to your hair?"

"Bleached it for experimental purposes."

"Pity. I liked the black."

Three days later he bleached it again, this time making it a red-ish color, close to Mycroft's. Everyone noticed this, except his mother. He hadn't even seen her that day, she suddenly became busy with business things Sherlock didn't care for.

Their maid noticed, though. He was standing in the kitchen, his back turned to her when she came in. She dropped the tray she was holding and gasped, startling Sherlock and making him turn around.

"M-mister Sherlock? What in God's name have you done to your hair?"

"I dyed it, experimental purposes."

"Your mother's going to kill you!"

"She won't notice."

"She pays more attention to you than you think, dear boy."

"Yeah, I'm sure."

"Besides, your brother will certainly notice."

"Ha!" Sherlock laughed as he washed his hands, "Right."

The maid just sighed and left Sherlock in the kitchen.

His mother didn't notice. In her defense, she only saw him three times in four days. On the fourth day, he came out of his room with very, very blonde hair, wearing a black button up and blue jeans.

"Oh my goodness, Mister Sherlock!" his maid yelled at him from down the hall. He grinned and went downstairs, where Mycroft was waiting to take him to school.

When Mycroft took sight of him, he spit the juice he was holding in his mouth onto the floor. "What the hell did you do to your head?"

"I dyed it for experimental purposes."

"What? Why? Mother!" Mycroft called for their mother.

"No use, she's not here."

"Where is she?" Sherlock shrugged. "Well, come on. You're going to be late, which means I'm going to be late." Sherlock picked up his bag and followed Mycroft. "And I'm taking you to the barber shop later. Or the salon, whichever will change your hair back to normal."

"Why? Now I match you."

Mycroft stopped, turned around, and looked at Sherlock. "Please, Sherlock. That's not the reason you did this. Mother's just very busy right now, ok? You don't need her watching your every move and she knows that."

At school, everyone stared at Sherlock. If they didn't already think he was a freak, they did now. He did look ridiculous, but he was willing to do anything for the sake of proving his hypothesis correct, his hypothesis being he is invisible. So far, he was only invisible to the one person he didn't want to be invisible to: his mother.

Sherlock heard a deep voice behind him. "Pretty little blonde boy," he said, "Are you going to keep getting more and more blonde?"

"No, I don't think so. I think this is it."

Jack pushed Sherlock against the locker again.

"You know, you don't have to push me," Sherlock said, struggling against Jack's grip, "I'm perfectly capable and willing to do anything on my own."

"Habit, I guess."

"Habit? It's happened twice."

"I can make it a habit." Jack brushed his lips against Sherlock's. "But I can tell you like it."

"No, I'm just willing, and-" Jack cut him off by kissing him again.

They made out against the locker until a teacher came and told them to stop. The entire time, Jack's hands were in Sherlock's hair. Part of him regretted turning it blonde, but at the same time he remembered that nothing and nobody can get in the way of his experiments.
