Y/N Holmes stood at the window of his office, his gaze distant as he sipped a slowly cooling cup of coffee. A bored expression painted his face, though the thoughts swirling in his mind were anything but idle.
The Moriarty brothers again... he mused, brushing a hand through his dark blue hair. "I've met two of them. I wonder what the third brother is like."
A knock interrupted his thoughts. A journalist co-worker peeked in, letter in hand.
"Apologies for the interruption, Mr. Holmes. This came for you."
Y/N took it with mild curiosity. "Thank you."
The door clicked shut behind the departing co-worker as Y/N slit open the envelope and unfolded the letter.
"Miss Hudson," he murmured after reading. "Of course she's worried about Sherly."
He sighed, glancing at the clock. "I guess it can't be helped. I'll head to York Station now."
***
The hum of the train station buzzed around Y/N as he made his way through the crowds. His eyes caught two familiar figures locked in an argument-John Watson and his older brother, Sherlock Holmes.
Y/N watched with a resigned sigh as John tossed a train ticket to the floor and stormed off.
"Sherly," he called out. Sherlock's head snapped toward him.
"Y/N?" Sherlock narrowed his eyes. "What are you doing here?"
"Miss Hudson sent me. She's worried about you."
Sherlock mumbled something unintelligible under his breath.
Y/N crossed his arms. "You've upset your companion. You should apologize."
"Whatever," Sherlock muttered.
"TO LONDON, PLEASE BOARD! THE TRAIN WILL BE DEPARTING SHORTLY!" came the conductor's announcement.
Y/N offered his brother a small smile. "Let's go, Sherly."
Sherlock scoffed, but followed him onto the train.
***
Once aboard, Sherlock stormed toward John's compartment, only to find it locked.
"Tch!"
"You must've really angered him," Y/N remarked, noting the doctor inside, hidden beneath his hat.
Sherlock grumbled something as he stalked toward the dining car. Y/N followed.
"Why does it feel like I'm the older one?" Y/N muttered as they sat down.
A waiter arrived with menus.
Sherlock glanced briefly before ordering. "Cold beef, mashed potatoes, and a beer."
"And you, sir?"
"I'll ha-" Y/N began, but Sherlock suddenly stood and sped off toward another table.
"Sherly!" Y/N exclaimed, sighing when he recognized the table's occupants.
"I apologize for my brother's behavior," he told the waiter. "Seems I'll be switching seats too."
He approached the table and offered a polite bow. "My name is Y/N Holmes. Apologies for the intrusion."
"It's quite alright. Please join us," the gentleman said with a gentle smile.
Y/N sat beside a familiar blonde man-Louis James Moriarty.
"Thank you," he said, then turned toward the bespectacled man beside Sherlock. His eyes widened.
