John and Sherlock had one class together. As it turns out, it was the class taught by Sherlock's brother Mycroft. Although this wasn't done on purpose, they both got a good laugh whenever they went to class together.

Usually, Sherlock would wait for John in the room and they would walk to that class together. Today was no different. They smirked while they were walking to the classroom. John always looked forward to whatever Sherlock had planned for his brother.

"I don't think I'm going to do anything to Mycroft today." Sherlock said as they reached the room.

They stopped outside the door before they went inside.

"That's new for you. Why the sudden change of heart?"

"I figured just letting him think I'm up to something is stressful enough."

They both laughed a bit more before heading inside. Sherlock gave Mycroft a devious smile as he and John walked to their table.

"Hello, brother dear."

"Sherlock, for the hundredth time, you are to refer to me as Professor Holmes while you are in my class."

Sherlock and John snickered a bit and took their seat. They were a few minutes early, so class hadn't started yet.

While Sherlock was looking down at his biology notes, he heard a soft voice in front of him.

"Hello."

He looked up to see a small, young, woman, clearly also a freshman. She had her brown hair back in a ponytail and stood nervously with her hands together at her stomach.

"Hello."

As John was sitting next to Sherlock, he listened to the conversation as well, but decided not to speak.

"Um, my name is Molly Hooper. What's yours?"

Sherlock look confused at first, but gave a slight smile and answered her anyway.

"Sherlock Holmes. Pleasure to meet you."

"I'm majoring in biology, what about you?"

"Same, and also forensic chemistry."

"Oh, so maybe we'll be seeing a lot of each other." Molly said with a smile. When she was met with a weird look from Sherlock, she appeared to become very flustered and tried to find the right words. "Oh! I'm sorry, I didn't mean to imply…no, what I'm saying is..."

"Molly, it's okay. Of course we'll be seeing each other." Sherlock said, interrupting her. She took this opportunity to apologize again and take her seat.

When she sat down, John leaned over and whispered to Sherlock.

"Is it obvious that she has a crush on you?"

"Crush? What are we in primary school?"

"Don't be modest, Sherlock."

"Well, she is rather cute, isn't she?"

Before John could answer, Mycroft started the class.

He taught for a little while and as he was just starting out, he would sometimes get distracted by Sherlock making strange faces, but he would quickly regain his senses.

John feverishly took notes while Sherlock focused more on irritating his brother, though occasionally he would jot things down if he felt they were important.

After about an hour and a half of class, Sherlock decided he had to use the restroom. He simply got up, walked out, and headed in that direction.

xXx

Once Sherlock was out of the restroom, he figured that Mycroft wouldn't miss him very much, so he decided to go outside for a quick cigarette.

He opened the doors to the building and stepped outside, smelling the fresh air and lighting the cigarette in his hand. He didn't get very far, maybe two or three drags, before he heard a somewhat familiar voice shouting his name a few feet away.

"Get Sherlock!"

Suddenly, Jim Moriarty and a few others sprung out from the side of the building and from some of the nearby shrubbery. Armed with water balloons, they threw all of their supply at Sherlock.

People around him ran from the commotion and watched from afar. Sherlock put his arms up to shield himself, but got soaked nonetheless. Jim gave him a devious smile before running away with his friends.

Sherlock wanted to chase after him desperately, but he chose to go back to the classroom first. He marched onward, ignoring the stares from those around him and walked into the classroom, stopping a few feet from the door.

"Mycroft, I have to go. I've been attacked."

John looked up from his notes and gave Sherlock a confused look, as did the rest of the class. Mycroft simply looked annoyed.

"Sherlock, this better not be one of your tricks."

Sherlock walked over to his table and grabbed his books, giving John a determined look. John could tell something was wrong.

"Not at all, I just have to go. Call me later."

Sherlock ran out of the room without giving him a chance to respond. Mycroft looked at John, indicating that he can go.

"You may want to make sure he doesn't get himself into trouble."

John thanked Mycroft and apologized for interrupting class. Mycroft assured him that he would not be marked absent, and John left to find Sherlock.
