Doctor John H Watson has been fighting for longer than he could remember. He fought the doctors who helped his mother while she was in labor as John fisted his tiny hands around his cord and refused to budge. He fought his big sister Harry when she tried to dress him up like a doll. He fought his fellow preschoolers when they teased him for being so tiny. He fought his peers in elementary school when they teased him for being so tiny. He fought older, larger boys in high school when they taunted him about his (lack of) height. He even fought his father's rules and snuck out of the house. So it was to the surprise of no one that John eventually went and joined the military later in his life.

John's fighting spirit could be blamed on his father, Ian, who was a warrior in his own right, a hunter that could rival the Winchester and Campbell name. Or the fact that the Watsons have been fighting for longer than they had been called Watsons. Or, it could be blamed on Leah and Daniel Watson, John's mother and younger brother, on the way that John, at the tender age of seven, had to watch helplessly as his mother was murdered by his own father and his brother devoured by their mother. Some may even say that John's fighting spirit comes from the hatred he held for the demon, Choronzon, that had initiated his mother's change.

Ian Watson stopped hunting after his wife's passing, heart-stricken with the pain of having to off his own wife, and he banned hunting for his remaining two children. When he wasn't working as a moving real estate agent, he was home wallowing in sorrow. Harry Watson avoided her father and remaining brother like the plague, staying late at friends houses and going to parties just for an excuse to stay out of their quiet, too large empty house. When she wasn't partying or drinking, Harry hunted, defying her father. Searching the woods at night and hiking the mountains with a set of knives and a loaded gun in her backpack. Countless times, John had packed his own bags, ready to set out with her. But Ian always caught him by the scruff of his neck, tossing him back into his room with a rough hand. Years went by like this and the home grew darker as time went on.

Around the middle of high school, John finally managed to break away from his father, away, even, from his sister. With only the vaguest idea of what he was doing, John caught a bus that carried him miles away from the familiar scenery of his home, and he followed a trail of gruesome, unsolved crimes through a distant countryside.

He thought he was ready, after all, he'd been preparing, training his whole life, it seemed. But he wasn't, nothing could have prepared him for the smell, for the sight, for the sound of bodies at varying states of decay, being torn into by jagged fangs. He managed but escaped by luck alone. John spent a good portion of that night retching into a bush, and sewing up gashes on his arms, legs, and chest. When he finally returned home, he was scolded nonstop by his father and nursed back to health by a disgruntled Harry.

Not long after John turned 17, he and his classmates were invited on a field trip to a local museum, which had been known for electrifying deaths in the basement. No one knew how the victims keep dying so they ensured the basement was blocked off at all times. It was this day that John met Sam and Dean Winchester, who were 10 and 14 respectively. Sam and Dean were spending their free time trying to sneak into the basement to hunt the ghost when John caught them.

John easily figured out they were hunter kids and decided to go along with them on a hunt just to make sure they didn't hurt themselves. To say Dean was annoyed with Sam and John by the end was an understatement. Then the trio wasn't busy dodging a ghost, Dean would be busy trying to end another sass battle between John and Sam. Of course, they almost regretted messing around when John died for a minute when the ghost electrocuted him.

Over the next two weeks, the trio would get to know each other and quickly become friends. They exchanged numbers so they could still contact each other when the Winchesters finally went back to even managed to send a few letters to each other and would help each other out when they needed it. The trio continued hunting in their separate countries over the many years that the boys knew each other.

During one of John's hunts, he ends up meeting a colony of vampires. It was half a year after John met the Winchesters and he was taking a summer trip alone before he started his senior year of high school. John traveled away from London and headed for Nottingham, defeating any monsters he came across along the way. The Alpha, Martin Nassir, managed to pull John to the side and explain that his family feed off of the blood back and wild animals. John did stay skeptical until he met the other hunters that were in town. Once he learned more about the hunters he decided to help save the vampires, who thanked him by adopting him into their family. They even decided to help support John through college as he started working to a medical degree a year later.

On his way back to London, John ends up meeting a cult of witches. This was the hunt that would change his life forever. The witches ended up hurting a lot of people and John was forced to kill all of them except one. One got away. She was a young brunette, not much younger than John at the time, and went by the name Ursula. Before she vanished, she cast a spell on John.

"Foeda omnia velis curam rerum articulo mortis passuri. Qui curat nisi pariter possit resistere morte solvatur maledictio."

At the time, John was unable to translate what she had said. By the time he could, he could no longer remember the full incantation. However, John looked himself over and he appeared to be fine so he thought the spell didn't work. What he doesn't know was that it had worked. The spell said: All those you wish to care for shall suffer horrible events to the point of death. Only if the one who cares for you equally can defy death, shall the curse be broken. Of course, Ursula didn't think it was possible for anyone to defy death and she had no way of reversing the spell.

When John finally returned home, a month before his senior year was to start, he was shocked by home much had changed in a short time. His father had become an abusive drunk and died a week later from alcohol poisoning, Harry and John were sent to live with their angry abusive aunt from their mother's side, and Harry quit hunting to hang out with the kids from the wrong side of the tracks. All of this happened within a month. At first, John thought it was just a string of bad luck.

As time went on, John's family wasn't the only one affected. John found out that his girlfriend of one and a half years moved across seas and could no longer stay in contact with John. Then his next girlfriend turned out to be psychotic and murdered any girl she saw as a threat. Thankfully she was placed in an asylum shortly after John broke up with her. When the young soon-to-be doctor started his years at Bart's University, he realized that he was bisexual and started going out with guys as well as girls. However, his luck with relationships seemed to stick with him.

His first boyfriend nearly committed suicide because of failing grades before John talked it over with him and decided they needed time apart. John's next girlfriend cheated on him for money. Then John and his first boyfriend got back together and John was too late to save him from suicide. John's next relationship was with a girl who ended up being addicted to drugs and was later expelled when a teacher overheard her trying to get John to try drugs. Then there was the boyfriend who got cancer and died after. To finish off his University years, John dated a girl who cut everyone out of her life shortly after her parents died.

Other than that, John excelled in school and found an informant named Philip that John would go to during hunts for information. Philip, or Phil, and John never physically met or give each other their last names but they did talk over the phone regularly and soon became friends. John made sure he was always at the top of his class and decided to go into the Military with his medical degree. Thus meeting his next boyfriend, a fellow Sargent who went insane during training one day. At this point, John decided to wait on finding a relationship until he returned home. That lasted shortly before he was promoted Captain and he met Sholto. Then Sholto's accident happened and John could no longer have him.

During his time as an army doctor, John would help war ghosts move on while also fighting off the enemy and patching up his comrades. He was a very busy doctor. There was one ghost that refused to move on and helped John get other ghosts to move on. The two were fast friends and even told John that one time the good doctor accidentally, miraculously, killed a reaper that was going after one of his mates while John was busy patching up another soldier. It scared the reaper's student half to death and he fled. This friendly ghost even knew a little bit of Latin and helped Watson carry out longer conversations, although he was still very shaky when he talked.

It wasn't long after that when John was shot and died for a minute before one of his war brothers managed to revive him. With his psychosomatic limp, John could longer hunt when he returned home. He did visit Harry and found out that her wife, Clara, died in a car crash shortly before John had returned home. John took notice that Harry was trying to drink her sorrows away, reverting back to the way she was before Clara became a part of her life. Not wanting any reminders of her dead lover, Harry gave John her phone.

A week later, John bumped into Mike Stanford, who was an old hunting and college buddy that was able to get out of the hunting life. Through Mike, John met Sherlock and their adventures began while John slowly fell hopelessly in love with the consulting detective. Over the next few weeks, John finds out a lot about Sherlock, including when the consulting detective gets too deep in thought to notice a language change. This is how John continues to practice his Latin.

Of course, it wasn't long before someone overheard John speaking in Latin. The first to find out was, unsurprisingly, Mycroft, who had placed cameras in the flat to keep an eye on his brother. The government man kidnapped John (again) and the two talked in Latin as Mycroft tried to figure out where John learned the language. John found it amusing that Mycroft was having difficulties trying to figure John out. The good doctor decided not to tell the government man that he was a hunter and that learning different languages was key to several hunts.

The next to find out was Mrs. Hudson, who John found out is a witch who specializes in healing remedies. John and Mrs. Hudson decided to keep each other's secret pasts from the rest of London, including Sherlock. Mrs. Hudson knew John would know Latin but she never knew how much he knew until she walked in on her boys talking to each other in Latin. Sherlock was completely focused on a particularly difficult case when Mrs. Hudson walked in with tea. John got up from his chair to allow their landlady to sit comfortably. Sherlock was muttering to himself and not paying any attention when John gave Mrs. Hudson a mischievous look, holding a figure to his lips. John started talking to Sherlock in Latin, telling the consulting detective to take a break and drink some tea. Mrs. Hudson had to hold back her giggles as Sherlock was oblivious to the exchange. She loved listening to her boys speak Latin, even if she doesn't hear it often.

The last to find out was Detective Inspector Greg Lestrade. The DI had come to the flat to get the information Sherlock was gathering while the consulting detective was being a prat. Sherlock was completely focused on the case and John was getting annoyed with Sherlock and Greg's bickering. So John took Lestrade's side and told Sherlock to stop being annoying. Surprising Greg when he heard another language come out of John's mouth. Later, Lestrade pulled John aside and asked where he had learned that from.

"I don't know what you mean, Greg," John would say, a far too sweet smile on his face.

John would tell the Winchester brothers and his Vampire family about the times when Sherlock and he would talk in Latin and each one found it funny that the consulting detective had yet to notice the language change. Harry even laughed, her day brightening just a little bit thanks to her little brother.

One day, Sherlock was being especially annoying and John was venting about it to Phil. Soon enough, John found out that Phil knows a similar person who sounded just as bad as his flatmate.

"He's a consulting detective who is amazing with his deductions but so rude to everyone except his flatmate," Phil told John. "I would definitely want to be friends with the bloke if it weren't for all his rude comments." John froze, not sure how to respond. How would Philip know his flatmate? It didn't make sense.

"Phil, there is only one consulting detective in the world. How do you know my flatmate?" John asked, hoping Phil isn't possessed by a demon. Philip was quiet for a long time before he finally spoke.

"John Watson?"

"Yeah?"

"It's Anderson." The two just sit in complete silence before laughing at the awkwardness of their situation. Anderson then explained to John that he is purposely mean to Sherlock so that the consulting detective will focus more on the case and not on the fact that he is a hunter informant.

After the Black Lotus incident, John was fired from the clinic and decided to get back into hunting. He was very careful of Sherlock, making sure to take every precaution to hide the hunting world from his friend and crush. John looked at no other person for romance, although he did say he was going on dates to hide the fact that he was hunting. The times he would 'stay over at his date's house' John was really just outside the city on an overnight hunt. During one of these overnight hunts, John bumped into Ursula again. She managed to escape a second time but not before informing John about the curse, refusing to tell him that there is a way to break the curse. John spent the rest of the night in his hotel room, gathering his emotions so that Sherlock wouldn't find out. From then on, John kept an emotional distance from Sherlock, not wanting his friend to get hurt because of the curse. His feelings for Sherlock only grew.

A couple weeks later, John was visited by one of Choronzon's lackeys while Sherlock and Mrs. Hudson was away. The demon offered to break the curse on John in exchange for his soul. The good doctor hesitated for a moment before refusing wholeheartedly. He refused to allow a demon to help him break an unbreakable curse. Mrs. Hudson later comforted the poor doctor.
