This story is dedicated to our family friend,

"Big" John Gallagher

"Ohhh...god damn." Jacob groaned. 'Where am I? Shouldn't I be in my bed?'

As he slowly pushed himself up, he opened his eyes to an odd and horrifying sight.

Looking around, he saw buildings, smoking or crumbled to dust. The reason it was horrifying was obvious. The reason it was odd? Well, multiple reasons really. The buildings looked midevel, there was a wall surrounding the place, and a bunch more. The biggest reason though?

He was the biggest thing there.

Looking himself over, he saw that he was still in the clothes he went to sleep in. His camoflauge jacket, black t-shirt, his denim blue jeans, and his favorite brown steel-toed cowboy boots.

Deciding he would find help, he turned and started to walk. While looking, many questions went through his head.

'Where am I? Why am I here? Is there a reason? Was it a coincidence?' All these and many more ran through his head as he walked. Little did he know, he was being watched.

xXxXxXxXxXxX

"Dammit! How did an abnormal get through the wall?!" Mikasa screamed in frustration. They plugged the hole, and one still gets through?

"What?!" Armin yelled, turning his attention from the fight between Eren and Annie, to see what Mikasa was looking at.

There, standing about a mile away, was a fully clothed titan. It had dark brown hair, and was wandering around.

"Impossible! Other than a Colossus, no titan can get through the walls!" Hange screamed as she too, turned her attention to the titan.

"Hange, Armin! Stay and make sure that Eren and Annie don't get someone killed! I'm gonna deal with the abnormal! We have two titans fighting it out here. We don't need a third!" Before anyone could protest, Mikasa took off towards the abnormal titan, unaware of what help it will bring.

xXxXxXxXxXxX

Jacob hadn't looked long, when he felt a sharp pain on his nape.

"YEOWWWW!" He screamed in agony as he dropped to his knees and gripped the wound with one hand while supporting himself with the other. "WHAT THE FUCK WAS THAT?!" He yelled as he looked around to see what could've gave him the wound when he spotted a girl, Asian maybe, staring at him with a look of shock. She was quite small compared to him. She came up past the rubber under his boots. She had a white shirt, some black boots, brown pants, and two odd looking devices attached to her thighs. She also held two swords with a string attaching them to said devices. The swords were covered in blood.

His blood.

"It...It speaks..." She muttered, her eyes wide, before full out yelling. "A titan spoke!"

xXxXxXxXxXxX

Mikasa was shocked. A speaking titan? Its definitly an abnormal. And it didn't die, even after she cut its nape!

It lowered its head to her, causing her to take a defensive position.

The titan rose up and waved its hand in front of it

"Woah! Wait! I didn't mean to offend you! I just asked what a titan was." It quickly said. Mikasa thought about what it had just said, and then froze. It didn't even know what a titan was? How? He is a titan after all. How could it not know what it was?

Thinking over this, she realized that despite its-no. Despite HIS size, he may not actually be a titan. Then again, he may just be playing her. Thinking over these possibilities, she decided what she would do.

Sheathing here blades, she finally spoke to him.

xXxXxXxXxXxX

"Back up to that wall over there." The girl ordered, while pointing behind him and to the building he was sitting in front of. Puzzled, Jacob did as he was told, backing up till his back was touching the building. "Do you have a name?" She asked. While he may have been bigger, he was taught to respect adults and elders. The girl looked to be in her early twenties. He was only 9.

"My name is John. John Gallagher. People normally call me Jacob. Whats your name?" He asked politly, spreading his legs and resting his arms on his knees.

"My name is Mikasa Ackerman. I'm an officer of the Survey Corps. How did you get in here, John?" She responded.

"Thats...a good question actually." He answered. "I go to bed as a normal sized 9-year-old human, and wake up in the road and find that I'm pretty much a kaiju now. Heh. The way things can work." He leand his head on the wall with a slight smile on his face, as if remembering something. Then his face turned to a look of horror. "Wait. What is this place?!" He questioned, turning his gaze onto Mikasa again. She backed up in slight fear before composing herself and calmly answering.

"Your in Stohess, behind Wall Sina. Why?" She was curious. Why would he ask that.

"No, I mean what continent!" Jacob corrected. She didnt know how to answer. What was a continent?

"Uh...what's a...conetinet?" She asked as she tensed.

Jacob felt his heart sank. She didn't know what a continent was? Then that meant-

"What year is it?" He asked her urgently. She relaxed. A question she could answer.

"It's 850. Does that help?" She asked, hoping to cheer him up. Unfortunatly, it did the exact opposite.

He covered his face with his hands. "8-800-50?" he stuttered. "No, no, no, no, no!" He rmoved his hands, allowing Mikasa to see the tears flowing freely from his eyes. If it were anyone else, she'd scod them for being so immature. However, it sounds as though he wasn't this size before, and he was only nine years old. He had made it sound like titans didn't exist where he came from.

"What's wrong?" She asked as she approached him.

"I...I've...appearantly, I've traveled to the past." He said slowly as he wiped the tears off his face. Now Mikasa knew something wasn't right. Not with the oversized boy in front of her, but with something else. This boy had no reason to lie to her, and she had know reason to believe he was. So this boy is from the future?

"What year are you from?" She asked as she was right under Jacob's face.

"2016." Now she was blown away. This 9-year-old boy was ripped from his family, not just a few, but over 1000 years into the future? And woke up the size of a titan. That must make it even worse.

"Hey, you always have a friend in me." She said in a motherly way as she reached up and touched Jacob's cheek.

A smile made its way on his face as he responded. "Thanks."

xXxXxXxXxX

It had been 7 minutes since Mikasa left to deal with that titan, and Armin was starting to get worried.

"She's taking too long! I'm going after her!" Armin yelled. Activating his Manuveur Gear, he took off in the direction that Mikasa went, hoping against hope that she was okay.

xXxXxXxXxX

Noticing movement out of the corner of her eye, Mikasa looked up to see Armin being reeled in with his maneuver gear, about to slice Jacob's nape. One may not have done it, but two will surely kill him.

"Armin! NO!" Too late. By the time she had finished, Armin was already on the ground with bloody blades, and Jacob was screaming in pure agony.

"Mikasa! Are you ok?" Armin asked he ran up too her. instead of recieving gratitude like he expected, He got a hard slap to his cheek.

"What's wrong with you?! Did I LOOK like I was in trouble?! JOHN WASN'T DOING ANYTHING WRONG!" She screamed at him as he held his cheek in shock.

"I'm...sorry. I just thought you needed help. Its been seven minutes. You hadn't come back." He said quietly as tears welled up in his eyes.

Realizing her mistake, she quickly calmed herself. Before she could say anything though, a voice familiar to her interupted.

"WHY DO PEOPLE KEEP DOING THAT?!" Jacob screamed as he stood to his full height. Now that Mikasa got a good look at it, she realized that whatever happened to must have changed him in more ways than just size. Whenever she first saw him, he was about a few meters smaller than Eren's titan, which was 15 meters. Now he was about 25 meters tall! And he was bigger. Now that she thought about it, the same thing happened when she first attacked him. And he slowly got smaller.

So whenever he feels pain, he gets bigger by 13 meters, and slowly gets smaller, until he is back to the size he was when they first saw him. If it did that to him, who knows what else it did?

Looking around, Jacob finally spotted Armin, and noticed something that he just had to ask about.

"...is that a girl with a boys voice?" He asked while pointing at Armin. They both had different reactions at this.

Armin's face turned redder than a tomato with anger and embarresment. Mikasa, after thinking about how he did kinda look like a girl, dropped to the floor laughing her heart out while holding her ribs.

"Mikasa!" Armin groaned, face still red.

"I'm sorry! But when he said that, I just couldn't hold it!." She apologized between laughs. She slowly got up off the ground. "I didn't mean to make you mad."

Looking up, they saw Jacob's attention was on something else. And based on the look of horror on his face, it was pretty. Using there 3D Maneuver Gear, they reeled up to a roof and saw something that made there hearts sank.

xXxXxXxXxX

Having finally risen to his full height, Mikasa and Armin's little squabble had lost his attention to the horrifying site ahead.

A quickly decaying body, 13 or so meters smaller than him, sat in a large crater in the side of a building as a brown haired girl with glasses cradled a black haired boy in an atire similar to Mikasa's. There was another being a meter smaller than the one in the building running away from the carnage. Noticing Mikasa and Armin on the roof in front of him, he heard Mikasa mutter one thing.

"No. Eren."

xXxXxXxXxX

Forgetting about Jacob, Armin and Mikasa quickly used there Maneuver Gear to swing from building to building until they landed softly on the ground.

Hange had tears in her eyes as she tried in vain to keep Eren from dieing. He had a hole in his stomach and was leaking blood fast.

"Come on Eren! Wake up! Please! You can't just sit and die!" Hange screamed as she did her best to keep him from bleeding out.

Mikasa had tears in her eyes as she listened and finally broke. Loudly sobbing, she flung herself into Armin's grip as she bawled.

Jacob had walked over and had been standing there the entire time. He knew they couldn't stop the blood flow and catch the thing who did this to the poor man. The only thing strong enough to stop the bleeding would be-

Wait. Something like his finger would be the only thing to stop the bleeding. But he needed to catch the thing that did this. He then got an idea.

'Both Armin and Mikasa cut my nape, which means blood should be running all down my back.' Feeling his back, he what felt only made his idea more possible. 'Dry. If my back is still dry, then what about my nape?' Feeling his nape, he didn't feel a large bloody cut, but instead, dried skin, as if it had never been harmed in he first place. 'Bingo.'

Getting down on one knee, he started to take charge.

Snapping his fingers, he quickly got Hange's attention.

"Hey, what's your name?" He asked as he pointed his hand at her.

"What's it to you titan?" She growled. "It was your kind who did this. He didn't deserve this, and your kind-"

"Lady, I just woke up to find my kind God knows how much smaller than me, and that I'm in the year 850 when I should be in the year 2016. And I've apparently been thrust into some kind of war. I've picked my side, so I'd appreciate it if you'd shut the fuck and let me help some one on my side." Hange was shocked. This wasn't a titan, but a human from over 1000 years in the future? "And before you ask, I don't know how I wound up like this. I'm nine years old, so I should be smaller than you and crying my eyes out. But when you grow up with the things I've seen, you're kinda unfazed by this. Oh, and one more thing." He got into Hange's face as he said what he did next.

"I don't know what a titan is, other than they are huge. But since I don't know what they are, call me a Kaiju." He than got out of her face. "Now, set him on the ground."

Doing as he said, Hange gently set Eren down in the grass. Jacob then put his thumb over the wound.

"I've stopped the bleeding, but I need to go after the bitch that did this. I'm gonna make my thumb go limp. When I tell you, try to lift it off him." He ordered. "Now." Hange, Armin, and Mikasa, who had quieted her sobbing, but was still crying, put there hands under his thumb and slowly lifted it off Eren, before setting it back down.

"Good. Now, Mikasa, since I trust you the most, I want you to take your blade, and cut off my thumb." Mikasa was shocked, but obliged. Drawing her blade she cut off Jacob's finger in one quick slice. He winced, but when compared to cutting his nape, it didn't hurt at all. As he had predicted, he had changed in more than just size. His thumb quickly started to regenerate, while the one he cut off stayed in place. He also noticed that while the now regened thumbs was even with his hand, it noticably larger than the one sitting on Eren.

Standing to his feet, he turned his gaze to the direction the apparent titan went.

"I'll be back. I got something to take care of."

"Where are you going?" Mikasa questioned with worry.

"After the bitch that did this." He responded. "Stay put."

Mikasa was beyond shocked now. He was nine, yet, not only was he willing to chase Annie, but he was willing to help people he didn't even know.

Before she cold say anything else, Jacob was already running after Annie.

xXxXxXxXxX

Annie didn't wanna fight Eren, or hurt him for that matter. She just wanted to escape.

She didn't mean to go that far. He shouldn't have died. She wished she hadn't beat him so badly. She wishe-

"Hey! Whore!" She heard a voice say behind her. Sparing a glance she saw a fully clothed titan running after her. He wore a camo jacket, black shirt, a pair od blue jeans, and a brown pointed pair of steel-toed boots. He had dark brown hair as well. He was chasing after her.

And he was gaining. Fast.

xXxXxXxXxX

Well this chapter took a while to write. I should have the second chapter out by tomorrow.

As I stated above, this story is dedicated to the memory of my family friend, "Big" John Gallagher. May he Rest In Piece.
