It's just another day, matt casey thinks. But it's not tomorrow he i0s suppose to marry his best friend. But today hes got shift. Its sylvies last shift before maternity leave.

They head out to the station, matt goes to get his morning coffee and sylvie finds stella and emily and talks to them.

Just then the alarms go off.

Building collapsed on 190 lake shore drive, all units respond.

Matt and rest of the house jump into action, Matt finds sylvie and says "stay safe, I love you both." Matt says kissing her with his hand on her belly and she smiles and says "we love you to, forever." Matt smiles and responds to her by saying "Always." They kiss and head to their rings.

None of them knew what today would bring. But it was a dark and dreary day, sylvie had a bad feeling in her gut.

They get to the scene it's a mess on top of the structure falling apart theres people stuck inside. Matt jumps into action and orders his men around.

He looks at sylvie with love in his eyes and nods to her.

She nods back and mouths "we love you." Matt smiles at her and heads inside the building.

Once in there he makes his way to the back where there was a day care and him and gallo start taking the children out but just as Matt is taking the last one out he hears a creak, a firemens worst sound. The floor starts to give he tosses the child to gallo, gallo rushes out to save the child.

The floor collapsed and matt gets thrown into the basement where the fire started, when gallo sees what has happened he yells into the radio. "MAYDAY, MAYDAY, FIREFIGHTER DOWN, ITS THE CAPTAIN."

When sylvie hears this her guts twists into a million knots.

Chief quickly sends Squad in and foster trys to comfort sylvie but she starts crying. Gallo comes out and brings them the child that matt saved.

"What happened?" Asked sylvie as foster takes the little girl and starts to triage her, while the chief comes over to them.

"Captain was bringing the little girl out when the floor gave out he tossed her to me and fell through. " sylvies got tears pouring down her face.

"I'm so sorry sylvie." Gallo says and she nods curtly. Chief gives her a one armed hug and says "he'll be fine hes a fighter, he has so much to fight for." Chief says.

"Thanks chief." Sylvie says.

Just then Severides voice booms out over the radio.

"We got him get ambo ready." Severide says.

"Kidd, you'll drive as foster works on him and sylvie goes with in the back." Chief barks.

"Yes sir." Kidd says

As she jumps into the driver's seat.

Severide and Cruz brings out casey

Casey is covered in burns and his mask is covered in blood, He's unconscious.

Sylvie sobs as she runs over to him.

Foster whispers to kids, "I can't get a pulse." Sylvie over hears and sobs harder, and says "come back to us baby, please."

Severide removes sylvie from the side of Matt's stretcher and trys to console her, even though he is a mess himself, it's his best friend, he can't lose another one.

"Hes going to be okay." Severide says as he holds sylvie while they try to get Matt's heart beating.

"Come on we gotta go, I got a pulse but its weak." Foster says

Sylvie hops into the back with foster and Severide yells at squad to load up, because they are following the ambo.

There's a patrol car that give them a police escort to the hospital.

Once in the ambo, foster tells sylvie "you need to prepare yourself for the worst and hope for the best, because honestly, it's not looking good."

Sylvie nods and silent crys as foster works on matt.

They had their whole life ahead of them, they were suppose to grow old together. This wasn't suppose to be the how it ended for them.

Sylvies head is spinning by the time they reach med and they whisk matt away, will halstead comes over to sylvie and says "we will do everything we can for him." Squeezes sylvie shoulder and then heads to the ED.

Kelly and the rest of squad burst into the waiting room, with truck and chief behind them.

Kelly and chief comme right over to the three woman. Kidd and foster got sylvie in a bear hug trying to calm her.

"Hey, this isn't good for the baby, you gotta try to calm down girl, I know it's hard, but you have to try." Foster tells sylvie as the men approach.

"Shes right sylvie, this isn't good." Cheif says giving sylvie a one armed hug.

"What if this is the end and matt never gets to meet our son, what if I never get to tell him how much I love him?" Sylvie says as she starts to hiccup.

"I know it scary right now but you gotta stay positive for you and this little guy." Kelly says hugging sylvie.

Just then there hear the code go of "Code Blue, we need a crash cart in here." Will says and that's when the world goes black for sylvie Brett.

The next moments of her life are all in a blurr. Matt cording on the table, kelly punching the wall, will coming out and telling everyone that he's so sorry for their loss. All she feels is numb, numbness over comes sylvie, she can't breath, she can't think. It's just heart retching sobs…
