Hello readers, here is a new fanfiction ! I have a lot of ideas these few days, so I wrote them. As you know, I like when Casey is hurt/injured (a little pleasure), so I made (again) a fanfiction about it, BUT, this time...

CONTEXT : The beginning of this story takes place after 2x20 (A dark day), around four days later. Therefore Leslie Shay is still alive and Matt Casey doesn't pop the question to Gabby already, who hasn't passed her final exam to become a firefighter.

SUMMARY : A horrible car accident let Gabby and Matt fighting for their life. And it affects all the firefighters of the firehouse 51 and their family, to the point to blame each other for what hapenned. Indeed, the firehouse 51 had been called on scene, freed them from their traps on a decision that divided Squad 3 and Truck 81. Will they manage to pass over it and become an united family to help Matt and Dawson? How will they manage to rebuild their life ?

DISCLAIMERS : I don't own all the characters of the three shows.

ALERTS : I don't know at all where this story will be going to, but I can assure you that if you want some thrills, you will have, as well as sadness and a lot of injuries too. I can't tell you if there will be a character death or not, I don't know for sure, but maybe I can make my decision with your help : please let me a review about what do you want and what do you think.

I will do all the story in a 3rd person POV, and I hope I won't make a lot of mistakes...

CHAPTER 1: Back at the firehouse

Gabby and Matt were still under the covers, enjoying the last four days off after the tragedy of Chicago Med, like all the firefighters who have worked in the firehouse that day. But today they were back to work. The sun began to illuminate the room through the blinds. Gabby opened her eyes and stretched, being careful to not wake Matt, still sleeping peacefully beside her. She loved watching him sleep, sometimes he was in a fetal position, sometimes in a star position. It was one of her greatest pleasures. She looked at her phone: 6:30am. She got up and dressed with her sweatpants and the shirt that Matt wore when he was a candidate. When she turned to him, she saw his big blue eyes. Those blue eyes she loved so much. Those of the man she loved. He smiled, waking quietly.

"Hello".

Gabby smiled back, and went back to bed near Matt and they kissed for a few seconds.

"What I love it when you wake me up like that".

"Oh yeah? Next time I will put the alarm on".

Matt had his puppy eyes, desperately trying to change her mind, but he failed everytime. They kissed again but Matt interrupted.

"Instead of making breakfast, we could go to this Starbucks before starting our shift".

"This is a good idea. But before that, we must take a shower and get dressed".

"Maybe... If we want to win time, we should take that shower together, don't you think?"

"I Think... That we will lose time if we do. And do you know why?"

"No..."

"Because... Every time we take a shower together, we begin to make love".

"Ah yeah? And this isn't because we are naked?"

"Maybe... Probably... Okay you're right I admit it!"

They kissed again and laughed at the same time. About half an hour later they were fully dressed and took the road to this Starbucks they had spoken. They took their usual formula and sat inside.

"I like when we come here to hang out before our shift" Matt said.

"Me too. It's on the road to go to the firehouse. Before and after shift we can come here and eat our breakfast or a coffee".

"Or both!"

"Generally Both!"

They laughed again. Four days ago, they were on the scene of that bomb attack and Gabby still had trouble to rebuild her life. Matt took Gabby's hand in his own.

"You know you can talk to me, right?"

Gabby looked into his eyes. She saw that he was serious.

"Yes I know. I'm glad you're with me. What would I have done if you hadn't been there?"

Matt tried to smile despite what she had just said. He knew how hard it was for Gabby to share her feelings.

"You were there for me after... Hallie. And you didn't give up on me. It's my turn now".

"You... You don't have trouble with that?"

Her voice... There was pain in it. Matt tightened his hand on hers.

"We all have break points. For me, it's when someone plays the hero and sacrificed his or her own life to save his or her family. For you, that's when you find yourself in a situation you can't control. We must live with it and move forward, otherwise it affects our work. In our work, a second of inattention can take your life. We all see horrible things, but this is our life, our job. The best job in the world".

Gabby listened Matt attentively. He was right. He was a firefighter, and she would be also one soon.

At the firehouse, everyone was already there, dressed for the beginning of their shift. And the fact that Gabby and Matt weren't still there was beginning to worry some of them.

"Maybe they spent these days off to coo!"

"Hermann..."

"What? I would have appreciated that if I had been at their place!"

"Hermann, It's not because you can't coo anymore, you need to see coo everywhere".

"Hey, I can still make love! I can't procreate anymore, not the same thing!"

All the firefighters couldn't help but laugh. Meanwhile, chief Boden entered the common room for some coffee.

"Casey and Dawson aren't still there?"

"No chief. They won't be long I think. This ins't Casey".

"He always comes early!"

"He's a lieutenant, it's logical for him to come before us! He must lead by example and should welcome his men. Anyway, I hope we won't have a call before..."

"If it's the case, you take the lead Hermann. I will have a talk with him and Dawson".

Firefighters were all worried, but Severide was even more. He knew Matt: if he wasn't there yet, something must have happened. He came out of the common room without arousing suspicion, went into his office, locked the door and called Matt.

Hello, this is Matt Casey. I'm not available right now. Leave me a message and I'll call you later.

It wasn't good at all. Severide had a bad feeling. At the same time, the alarm rang.

"Truck 81, squad 3, ambulance 61. Car accident. North Wabash and Washington".

And Matt weren't there. He was going to have an argument by Boden on his arrival. And so will Gabby.

"Come on Gabby! We'll be late for our shift!"

"Don't worry Matt".

"Gabby, I am a lieutenant and you are the PIC. We're both leaders, and we must be there before our men. And now, we will arrive after them, and Boden won't like it".

"But we will be at the firehouse in time Matt! It's two minutes away. There won't be any call, don't worry".

Matt wasn't worried, but he knew his chief: Boden won't let this go. So to go faster, he ran to his car to start it, the time for Gabby to cross the road. Suddenly, a loud noise came out of nowhere, and made him turn. He saw Gabby in the middle of the road and a pickup whas trying to brake hard. But its speed was too great, and he knew that the worst will arrive: the car was going too fast.

"GABBY!"

Without thinking, he began to run toward Gabby. During these endless seconds, in his head, everything was in slow motion. The pickup that wasn't braking yet and arriving too fast, Gabby staying there, totally paralyzed, frozen, and him running toward Gabby to save her. Grabbing her arm, he had just enough time to push her violently to the ground. He barely had a quarter of seconds to be relieved. Just before being hit by the truck at full speed.
