A/N Hey everyone! Here is the first chapter of my new story! For the first few chapters, I am gonna do prior series chapters meaning the chapters happen before the series starts and I will state when each chapter happens in regards to the show.

ONE YEAR PRIOR

Ignacia hops out of the cab after she pays the driver some money and grabs her duffle bag, the only thing she brought from home filled with clothes to the rim. She turns to look at the fire station in front of her and sighs and pulls her small coat tighter around her body as she walks toward it. The garage doors are open as a man notices Ignacia and walks to her

"Hi ma'am. Do you need any help?"

"Hi. I am looking for Chief Wallace Bowen."

"He is in a meeting right now but you can wait for him in the briefing room. May I ask who is looking for him?"

"Ignacia."

"RIght this way Ignacia. I am Brain but my friends call me Otis."

"Nice to meet you."

Otis shows her the way to the briefing room as she puts her bag on the floor and leans on the table when she notices the small group of people outside the room but doesn't pay attention to them.

"Why do you think she wants to talk to chief?"

"I don't know. Is it me or does she remind you of someone?"

"To me, she kinda looks like Severide."

It was true. Even though she was a little darker and she had brown hair, she generally looked like Severide.

"Oh here comes Chief."

" When I told him, I swear he smiled."

"Now where is my wonderful niece?!" Chief Boden yells as he walks in the briefing room and pulls Ignacia in a giant bear hug. The firefighters mouths are gaping open as Boden and Ignacia huh and start talking.

"So how is everyone back home?"

"Well Quetzal just started fifth grade."

"Woah that's incredible. Your mom?"

"Mom is not doing okay, she got diagnosed with dementia."

"Poor thing that is just awful."

"Docs say that it's worrying cause of how young she is and how bad the dementia is."

" That is just sad. So what are you doing here in Chicago for?"

"Well, my mom and I were talking and she mentioned that my real dad used to live here and that he had a son here I can't stay long. I need to head back soon to care for mom and Quetzal, my aunt is watching them."

"That's true, he does. Does that son know who you are?"

"No sir. His dad well my dad wait...our dad said that he never told that son about me."

Chief Boden sighs, "Well why don't we go meet this son."

"Wait really?"

"Of course. Let's go."

The two head out of the briefing room as the firefighters are gathered by the counter when Chief Boden clears his throat and everyone turns around.

"Is this everyone?"

"Yes sir, Chief. Everyone who's shift is now." A young man with dirty blond hair and piercing blue eyes stands tall and nods his head toward Boden.

"Well everyone except Cruz and Severide. They went to get food." Another man says as Ignacia looks at Boden who nods.

"There they are." The blond says as a Blue Corvette comes to the garage doors and two men come out with bags of takeout. They bring it to the kitchen.

"Go ahead and grab your food." Boden directs as the firefighters start to grab their food when one asks,"So who is this?"

"Gentlemen, I would like to introduce you to former Army firefighter Ignacia Severide Rodriguez." All the men cough up their food and go into coughing fits.

"Did you say Severide?" A man asks who looks familiar to Ignacia.

"Yes he did. My father is Benny Severide." Ignacia cuts in and the man looks at Chief who nods.

"Ignacia may I introduce you to Lieutenant Kelly Severide."

Ignacia turns to Kelly

"So you are the famous son I hear all about when I talk to Benny?"

"Um yeah I guess."

"Woah it's so great to finally meet you, that is one of the reasons I came. To finally meet you and to spend some time with my Uncle Boden." Ignacia says looking up at Boden who smiles.

"Uncle Boden?" Kelly says

"Well I call him my uncle due to the closeness of his friendship with Benny."

"I need a minute." Kelly says as he walks out of the kitchen.

"That went better than I expected." Ignacia jokes and Boden chuckles.

"Ignacia meet the rest of the firefighters here at 51."

The man from earlier pops up

"I told you already but I am Brain aka Otis."

Another man comes forward.

"I am Randy McHolland aka Mouch."

"Why Mouch?"

"Cause apparently to them, I am part man and part couch."

Ignacia laughs softly when the blond man walks forward.

"I am Lieutenant Matthew Casey, aka Matt."

Ignacia nods her head softly when another man comes up behind him

"I am Joe Cruz."

One more man comes up

"Andy Darden."

"It is amazing to meet you all. Chief tells me all about y'all when he calls and we talk."

"So this is why you wanted us to get an extra meal, Chief!" Joe says as everyone laughs.

"Sure did. Let's eat!"

"Oh what did you get?"

"Some Mexican food."

Cruz grumbles, "Al decir mexicano pero ni siquiera está cerca."

Ignacia, "Apuesto. Podría ir por algo mole de mi Madre."

Cruzlooks at her, "¿Sabes cómo hacer mole?"

Ignacia nods, "Aprendí de mi madre."

Joe smiles and nods his head when a throat cleared makes them turn to see Chief. They awkwardly smile as they get ready to eat when the alarm rings through the station. "Squad 3 Truck 81. Need for assistance at house and garage fire. People still inside." The men go and get suited up as Chief looks at Ignacia, "Well let's go! You can stay near the truck!" Ignacia smiles as she runs to catch up with her uncle and gets in the truck with him.

They drive to the house fire where there is already fire trucks and an ambulance crew. Ignacia gets out but stays near the truck when the firefighters start getting situated. "Cruz! Mouch!" Get the hoses ready!" Matt says. "On it!" Then, a young Japanese woman comes running out of the fire screaming and yelling in Japanese. The ambulance crew tries to calm her down but the woman is shrieking and yelling in Japanese. Ignacia hears and runs to the woman.

"Dō shita no?"

"Musume wa heya ni tojikome rarete imasu. Otto ga shisshin shimashita!" Ignacia turns to Boden,

"Her daughter is trapped. Her husband has fainted inside."

"Where is the girl and husband?"

Ignacia turns to the woman, "Karera wa doko ni iru? 2-Kai ka 1-kai ka?"

"Otto wa daidokoro no yuka ni imasu! Watashi no musume wa kanojo no heya ni imasu! Sono mado!"

"Her husband is on the kitchen floor. Her daughter is in her room where that window is!"

"Severide get the girl! Herrman and Casey, get the man."

"Yes sir chief!"

"Anata no musume no namae wa nanidesu ka?"

"Karuna."

"Her daughter's name is Karuna."

Severide nods and goes up the ladder as Herrman and Casey go to the kitchen.

"Found the husband!"

"Copy that!"

"Karera wa anata no otto o mitsukemashita." Ignacia tells the woman

"Soshite musume?"

"Kare wa ima ikimasu."

"Severide report on the girl."

"I found her chief but she seems scared of me. I can't get her to come closer."

Ignacia turns, "Let me try."

Chief gives her the radio

"Severide are you near her?"

'10/4."

"Okay let me try something. Kon'nichiwa, Karuna. Anata no mae no otoko wa anata o tasukeyou to shite imasu. Kare wa anata no okāsan ga iru basho no soto ni anata o tsurete ikimasu. Tada kare ni mukatte ikeba, kare wa anata o soko kara tsuredashimasu.' " Ignacia says as she is leaning on the truck

A few seconds pass as the silence is tormenting when suddenly, "Got the girl on our way out!"

The firefighters cheer as Ignacia turns to the woman

"Kare ni wa anata no musume ga imasu. Kare ga dete kimasu."

Just then, Severide comes out of the house carrying the small little girl.

"Karuna!"

Severide takes the little girl to the ambulance where the mom runs up as the paramedic is checking Karuna.

"Nani ga mondaidesu ka?" The woman asks as she sees her husband on the stretcher

"What is wrong with both of them?"

"He just has some smoke inhalation but is stable. No burns or nothing. She looks like she has smoke inhalation and a small burn on her hand. Most likely touched some metal."

"Kare wa kemuri o sutte iru dakedesuga, antei shite imasu. Yakedo wa arimasen. Kanojo wa kemuri o sui,-te ni chīsana yakedo o otte iru yō ni miemasu. Hotondo no baai, kinzoku ni furemashita."

"We are gonna take them to the hospital to be treated. She can ride with us."

"Karera wa byōin ni tsurete iku tsumoridesu. Anata wa karera to issho ni noru koto ga dekimasu."

"Daijōbu arigatō. Subete ni oite!"

The woman hugs Ignacia tightly and gets in the ambulance as the driver closes the door. The ambulance drives off as Ignacia walks back to Boden's truck as the firefighters are putting the fire out as Severide is talking to Boden.

"That was amazing Ignacia." Boden commends her.

"Thank you Chief."

"That really was. The girl's face lit up when she heard you talking through the radio." Severide adds

"Thank you." Severide is about say something else when Otis yells out

"Fire is out chief!"

"Alright lets pack it up!" Chief says as he goes to his truck and Ignacia follows him and gets in. The firefighters pack up the trucks as they get ready to leave.

The firefighters drive back to the station and take off their gear and such when they head into the kitchen and start to warm up the food that was left. Ignacia is beginning to eat her warmed up food when Severide comes with something in his hand.

"Hey uh Ignacia? I have a question."

"Yes sir?"

"Is this you?" He hands her a photo. She gently takes it. Its an old photo where she can easily tell that it is her as a baby. Then there is her father Benny holding her and then right next to both of them, is a small toddler.

"Yes it is. Is that you?" She asks pointing to the toddler.

"Yeah it is."

"So we have met?"

"Apparently."

"I have the same photo."

Ignacia leaves to go grab her duffle bag and opens it to see a small wallet. She opens it and pulls out a folded photo and shows Severide. It is the exact same photo,

"Woah."

"Benny said that we never met."

"Why do you call him Benny, I mean he is your dad."

"Biological father. My dad is in Texas."

"Well okay then. I guess we really are siblings."

"Are you okay with that?"

"Of course I am okay with that. I am happy to have a little sister."

"And I am happy to have an older brother. I'm so used to being a big sister."

"Really?"

"Yeah I have one little brother."

"Woah that is incredible. It is a small world after all."

"You better believe it."

"Why don't we go finish our food and you can tell me about that family in Texas?"

"That sounds very nice."

The two siblings go back to the kitchen to see everyone talking as they smile and go sit down and begin eating again.
