In this story you'll find some reference of the "event" in the story "No Sincerer Love". It will make sense without having read it but no harm knowing what's going on in that story. Naturally The Enhancement of John Watson takes place after "No Sincerer Love" - about a couple of weeks later.
Yes, I could have drawn out the events of this story but I think it makes a nice read as it is. Since it is almost finished, updates will be quite frequently.
John didn't make a sound while the paramedic dabbed the wound at his knuckles with antiseptic. He was still way too agitated to notice the stinging.
"I don't think you need stitches," the woman told him. "I dressed the bruise and your hand should be as good as new within a few days."
He could have told her that himself but John only nodded and let her do her work.
"There," she said, and gave her patient a pat on the shoulder.
"Thanks," John said and left the ambulance to come face to face with Greg Lestrade who had waited for him. The DI stood with his arms crossed in front of his chest and for a moment John wondered if he would punch him in the face or arrest him.
Instead, the grey-haired man surprised John. "You need a lift home?"
For a moment John was speechless but then he nodded and climbed into the car. They drove for several minutes without speaking. Finally Greg spoke up.
"When I heard what he did, I was pretty angry too."
Not certain how to reply, John made a non-committal sound that could be translated into almost anything. 'Punch me in the face' seemed to be the subtext in the normal speech pattern of both Holmes brothers and the doctor for once had acted upon it and punched Mycroft.
"Mycroft is going to be a pain in the arse for the next two weeks. A piece of one of his incisors was broken off when you hit him," Greg added.
John already knew because said tooth had broken the skin of his knuckle.
"Not the pain in the arse you would enjoy, I presume," John dead-panned.
"Arsehole!" Greg replied, the following chuckle ruining the curse. "Did Mycroft explain why he sent Sherlock to Springfield? The last I heard on the news half the town is burning from the riots, at least eight people were killed and the state of emergency was declared."
"Actually he did. A favour for the PM and I'm damn sure he could have refused. That's the reason why I punched Mycroft and why I need to be at the airport no later than 7:30 to catch a flight to New York."
Greg's eyebrow's shot up. "Mate, I don't want to sound pessimistic but I don't think you'll get a flight to New York without prior booking these days."
"Not if you fly first class," John replied, waving Mycroft's credit card in front of Greg's face. The good doctor apparently had taken a leaf out of Sherlock's book.
"Definitely a pain in the arse." Having stopped at a red light, the DI banged his head against the steering wheel. "I hope Mycroft is not going to start a war."
"Perhaps you could, uhm, distract him so I'm not getting arrested the moment I arrive at JFK."
Greg studied John from the corner of his eyes. "You do know that I love that man?"
"That's exactly why I'm asking you and not his secretary."
John produced a satisfying "oof", when the DI's elbow connected not too gently with the doctor's ribcage.
"All right, I'll try. But if he finds out about the credit card, you're on your own."
