John Watson didn’t stop to think. The fact that he and Sherlock were already late to meet Lestrade at a fresh, new, and conveniently nearby crime scene completely left his mind. He saw a man get blindsided by some punk kid on a skateboard and fall hard on the ground while the assailant rode on. John immediately rushed to his side.
He shoved his way through the small crowd gathering to gawk at the man with morbid curiosity. It was easy to see why; on top of the spectacle, the man was rather odd-looking in general. Mid-thirties, early forties but with a forward-sweeping spike to his hair, a brown pinstriped suit paired with white Converse of all things, and a long, tan overcoat to put it all together. It was a wonder how this strange person had escaped the skater’s notice. Luckily the chap didn’t seem too badly hurt, but he was groaning something terrible and clutching his head.
“Steady on, mate. I’m a doctor, and you’ve been hit hard.” John spoke evenly and kindly as he knelt by the man and moved his hands away from his face so he could check for signs of concussion. “Do you remember what happened?”
The chocolate-brown eye John was holding open zeroed in on him, and the brow above it furrowed. Then his hand shot to his right shoulder and scrambled around, as though he were looking for something.
He started to sit up quickly, but John stopped him with a hand to the chest.
“No, no, don’t get up too fast–”
The man shoved John roughly away, knocking him on his arse. Then he got on his hands and knees, calling out some strange word that John didn’t recognize. It almost sounded like a rejected spell from Harry Potter.
Regardless, John stood and made one last attempt to calm the man down.
“Sir, you need medical attention,” John insisted.
The man shook off the hand John laid on his shoulder, then jumped up to his full height. John blinked as the man loomed over him, despite only being about half a foot taller than him. His eyes, while clear, were crazed and deadly.
“I don’t need a doctor. I am the Doctor. Now go. Away.”
John stared as the man went back to searching the ground. By then the thin crowd had been scared off by the man’s apparent madness. “Alright, man, suit yourself,” the doctor muttered as he backed off. Clearly the matter was out of his hands, and he was on his way to see Lestrade anyhow. Perhaps he could tip the detective inspector off, and send someone over to deal with the situation.
“Well, I tried,” sighed John as he approached Sherlock, who had waited for him. “Let’s go, I guess.”
“Actually, John, you go on ahead,” said Sherlock.
John frowned. “But Lestrade–”
“Something’s come up. Besides, I highly doubt he has anything you can’t handle on your own. Meet back at the flat.”
And that was it. Sherlock walked off without another word, leaving John confused and more than a little annoyed.
