Hello everyone. Here comes my fanfiction:]. If anyone wants to know one of my theories about Marcus' heart, read this story. Read & Review, please.

Bear in mind that English is my second language (I'm Polish) and don't laugh at mistakes I could have made.

"The world is unfair."

Sarah put her hands in the pockets of her gray ranger trousers and looked under her legs because there was a hole in the concrete curb she was walking on. She jumped deftly about it and went on. She raised her head and rolled her eyes in the general direction of rain clouds hanging low above them. It surely was going to rain and she hoped that they would return to the base before first heavy drops fell down. She looked trough her red asymmetric fringe at Marcus who was walking next to her. He said nothing.

"The world is unfair," she repeated, looking at him expectantly.

"Sure it is," he said after a short moment of silence, smiling with one corner of his mouth slightly raised higher than the other. "Instead of taking care of important matters, I'm taking care of you."

"Hey!" She snorted, pretending to be insulted. If she stretched her arm, she could have slapped his back but she decided not to. He wasn't serious. He was just chaffing her like always. She quickened her pace, jumped on the ground and run down damaged stairs on the small square. If she had looked at her companion, she would have seen that he sat on the bottom step of the stairs like he did it always when they were here.

Sarah crossed the square and moved in the direction of the wreck of a helicopter. She stopped near the machine and squatted down among high grass to move her fingers across the granite tombstone.

"Hi, dad," she said silently, staring at the carved inscription. John Connor, 02.28.1985 – 07.04.2032. For the glorious future. The Resistance. She sat cross-legged on the ground in front of the dark tombstone and put her finger against the letter N, starting to draw its thick, angular shape. "It will have been sixteen years tomorrow since you died. Tomorrow mum, JJ, your soldiers, they all are going to visit you here. I'm earlier like always." She smiled. "Every year I have the same thoughts, you know? The world is unfair. Your soldiers think that you died fighting a terminator. They don't know the truth. But if they did… I think it wouldn't change anything. You were a hero for them, a brother in arms, you always fought, never gave up, you were tough, brave, fearless… It's unfair that you were killed by a heart attack. The world is unfair."

She started to draw the shape of O. She was close to start crying.

"I wish I had met you, dad. Why didn't you stay with us seven days longer?..." She sniffed. "It was just stupid seven days longer, daddy… Why did you die?..."

She burst into tears. It started to rain and she thought that the sky was crying with her. Suddenly she heard footsteps behind her and thick warm coat covered her shoulders. Marcus was standing behind her. Just a centimeter and she could have leaned against his legs.

"Let's go," he said mildly. She nodded, getting up.

They moved to the stairs. She didn't even know when she took him by the hand. They walked among some buildings in ruins and Marcus pulled her in the direction of the closest one. After a while they were inside.

She put her arms in too long and too wide sleeves and wrapped herself in Marcus' coat. She sat on a pile of rubble and wiped her wet eyes and face. She heard her companion walking to and fro across the room which had been a hair salon once. Finally he sat with his legs crossed on the dirty floor next to a broken window. She looked at him. He was staring at the rainy world outside. She sniffed.

"I'm listening to you," he said silently. She nodded.

If it hadn't been for Marcus Wright, she didn't know how her life would have been like. She was born a week after John's death. Kate couldn't have reconciled herself to his death. Nor did his firstborn son, John Junior, who had been five at that time. The Resistance lost their leader and chaos reigned. The machines decided to grab an opportunity and they attacked. And then Marcus turned up. The mysterious newcomer quickly won John's soldiers over. They went with him and fought. They won the battle but they found out who Marcus really was. His secret came to light when he had saved Kate and little Sarah from a terminator. A terminator that he defeated with bare hands. After that it was Kate who came to his defense and he joined the Resistance. A machine with a human brain, an outcome of some mad experiment left in the basement of the SKYNET's lab and faded into oblivion suddenly woke up to be together with human beings.

Marcus always thought about himself as a real human but it was only his brain that was real. He was strong, fast, resilient. He didn't have to eat and drink, he didn't feel cold nor hot and first of all he did not grow old, he had been looking the same since Sarah was a child. The world was changing, he was not. And she liked him for that the most.

"Speak your mind, Sarah," he encouraged her.

"You believe that if somebody in the first version was killed by a gun, he or she will be killed in every another version in the same way?"

She knew how much time that man – yes, a man, for her Marcus was a man, not a cyborg like he was for some people – devoted to understand the structure of time. He sighed and leaned his head against the wall behind him. For a moment she could see the sharp line of his masculine jaw.

"Every year we have the same conversation, Sarah," he said with a serious tone in his voice. "But you are smarter with every year. You know my theory well. Yes, if we suppose that this now is the first version of our story and your father died because of a heart attack, his heart will be the cause of his death in every another version."

She bit her lower lip, listening to the sound of rain outside.

"I have been thinking about all of this", she confessed. "My dad needs a new heart, 'coz the old one will sooner or later break down, doesn't he?"

Marcus nodded. Suddenly a cat jumped through a broken window. It was small and ginger-striped. The kitten shook his wet fur, came closer to Marcus and brushed against his knee. He took the kitten softly and put it on his thigh to pet with his big, heavy hand. The animal closed its golden eyes, purring loudly.

"I know what we have to do." Sarah got up and her protector looked at her. The girl walked across the room in Marcus' coat. Her quick movements scared the cat and Marcus held it because it wanted to run away. John's daughter sat on the floor in front of her friend and she petted the kitten.

"You're the most important element of my plan", she said to him.

"Do I have to be afraid of your plan?" he asked with one of those smiles she simply adored the most. She touched his left breast. He looked down at her hand. "Forget my question. Now I'm really afraid of your plan."

For a moment they were sitting in silence. His chest was empty. Silent like always. She patted his muscular torso and stood up. It wasn't raining anymore, so she went outside.

Without thinking she stepped with her heavy army boots into a deep puddle and stared at her shoelaces floating on its dark surface.

"You're such a weirdo today." Marcus bent down and put the cat on the ground. It meowed sadly probably wanting more petting.

"Thank you. I'm doing my best I hope." She smiled. "Are we going back home? I have a lot to do."

"Are you going to give me my coat back?"

"You don't need it."

"But I like it."

"I'll think 'bout it." She flashed a rakish smile at him.
