Reincarnated in a supernatural universe * Dropped*

Waking up with a headache after hearing someone scream, "Mary, no!" he looked around his room, having a weird sense of déjà vu, as if he had seen it before but could not remember it at the same time.

Bam! The door was kicked hard, and a man quickly came in, picked him up from the bed, and ran downstairs. While this was going on, he felt very disoriented, as if he hadn't completely woken up, but he could feel heat and smell smoke in the air, and he thought maybe the house had caught on fire.

They went outside and ran toward a kid holding a baby in his arms. The man shifted him to his right hand, picked up the other kid holding the baby with his left, and ran toward the road.

His head started to clear a bit, and he began to panic as to why he was in the body of a young child. He quickly turned his head to see the house engulfed in flames. As they arrived at a safe distance on the other side of the road, the man put them down.

A bit later, after they were checked for injuries by the medical staff of an ambulance that came fairly quickly and answered some quick questions from the police, they went to the nearest motel.

The man left, telling them he would be back in the morning, putting him in charge of watching over the other two. It boggled his mind how he thought this was a good idea; in what world was leaving three kids, the oldest not even seven, alone in a crappy motel something an adult should do?

"At least they fell asleep quickly... whatever, now I have some time alone with my thoughts."

Having somewhat of a clear mind now, a few memories came flashing into his head that he hadn't had before, and he began to realize where he was. He remembered that his name was William Winchester, the oldest child of the family born December 1977, his brothers being Dean, born on January 1979, and Sam, born May 1983, his mom Mary, and his father John.

He began panicking again, thinking, "I reincarnated in Supernatural, FUCK!"

In his previous life, he was what some might consider an otaku, with a love for watching and reading any story he could get his hands on. One day, he discovered fanfics, and he instantly loved them more than any stories out there. One might think that he was happy with being reincarnated, but that was not the case because of the world he woke up in—a world with gods, angels, demons, and a lot of fucking monsters, a world where one could find himself dead very easily if some supernatural entity came anywhere near him.

And with the family he was reincarnated into, coming across the supernatural was a daily occurrence. In this life so far, before this event, he lived it like a robot, with no emotion, as if he had not been all there before and just now woke up. So he thought, "Maybe I didn't take over this child's body, thank God... wait, THE GOD of this world goes crazy at the end of the show... I have to start planning and take advantage of my future knowledge so that maybe I can survive what's coming."

His mind was still a mess, so he lay down and started sorting through his old and new memories. The first thing he noticed was the lack of his personal memories, like his old family and friends and the circumstances of his death. Oddly, the feelings of sadness that he was not going to see them again were still there, even though he could not remember them.

From all the things he could remember perfectly, he realized that his memory was a lot better. It wasn't a photographic memory as he saw in some movies, but it was very close to it, he also thought that his brain was now that of a child, so it should get better as his body matured.

After a few minutes of sorting through the memories of his old life, he then started to go through the new, very confusing memories of the world he woke up in. He was confused because him being born into the Winchester family was not the only difference in this world.

Some of the differences were that people who should be dead weren't, like the grandparents from his mother's side. So he concluded that this was an AU Supernatural, and that wasn't a good sign for multiple reasons. The biggest advantage he had of knowing future events couldn't be heavily relied on anymore.

Broken from his thoughts by a strong feeling that three people were going to come through the door, he realized that he had spent the rest of the night organizing his memories. Quickly, he woke up Dean, gently grabbed the still-sleeping Sam, and hid under one of the beds in the room because it should only be his father.

A few seconds later, he heard the door open and his father's voice, "Boys, where are you?"

Releasing the breath he didn't realize he was holding, they came from under the bed. You could tell John was relieved to see them, and he was not the only one. The two other adults in the room smiled as soon as they saw them, and Will immediately recognized them as his grandparents, Samuel and Deanna Campbell, from the show and his memories as a child when they came to visit.

"John Winchester, you are lucky my grandsons are okay, or else... how could you leave them alone after ... what happened, Come, kids, give your grandma a hug."

After they gave both grandparents a hug, John cleared his throat to get everyone's attention. "Kids, from now on you are going to live with your grandparents." Immediately, Dean wanted to say something, but his father interrupted him. "Dean, I'm going to be on the road, and your grandma is right when she said that's no place to raise three young children, so I'll need you to watch over little Sammy and keep him safe in my place."

John hugged Dean. "I promise to come visit you boys when I can."

After a while, John gathered his things, said goodbye to the rest of them, and then left.

"Dear, take little Sammy, and let's get out of this shithole," Deanna immediately turned to her husband. "You will learn to control your language now that we have children around, or I'm going to wash your mouth with soap." "Yes, ma'am, I'm sorry."

After chiding him a bit longer, she took Sam in her arms, then guided the other two boys out of the room.
