Authors note this story is my first crossover attempt and its completely made up.

It was approaching late afternoon in Chicago and paramedics Gabriella Dawson and recent new comer Sylvie Brett where parked up in ambulance 61 drinking a coffee. It was one of the very few occasions that the crews on the ambulance could just relax. Brett couldn't help but notice that Dawson had been smiling all throughout their shift. Brett smiled as turned to face Dawson who was sat in the passenger seat.

Dawson who was trying to hide her smile looked at Brett "what?" Dawson asked just before she took a sip of her coffee.

"Nothing but you've been smiling all day and you seem oh I don't know happier than usual" Brett replied.

Dawson continued to smile at Brett before she finally spoke. "Casey asked me to marry him last night" Dawson quickly said which caused Sylvie to suddenly sit up and look eagerly to her friend "well what did you say?" Sylvie asked as she bounced in her seat. Dawson continued smiling "well I obviously said yes" Dawson cried in happiness. Gabriella Dawson was engaged to lieutenant Mathew Casey of Firehouse 51. Dawson smiled as Brett lent over and gave her a friendly hug "oh but don't tell anybody because married couples can't work together" Dawson quickly spoke just as ambulance 61's radio crackled into life.

"Ambulance 61 male unresponsive down an alleyway on east and 63rd street" a voice over the radio crackled. Dawson and Sylvie both smiled at each other as they were slightly annoyed because they only had an hour left on their shift and where hoping that they could avoid a call.

Brett turned ambulance 61s engine on and looked to Dawson. "It's either a drunk or a drug addict" Sylvie assumed.

Dawson laughed as she picked the radio up. "This is 61 we'll be there in ten minutes" Dawson sighed before Brett drove off. Brett continued to wave in and out of heavy traffic until she finally pulled down an alleyway. Both women felt slightly uneasy as they climbed out of the ambulance. The alleyway was full of bin bags boxes and trash cans "well where's the unresponsive male?" Brett asked as she walked to the back of the ambulance where Dawson was standing.

Dawson looked around equally confused. "61 to main we've arrived at east and 63rd there's no sign of anybody but we're going to look around" Dawson spoke over the radio. "Ok Brett take the right I'll go left radio if you find anyone" Dawson ordered before they split.

As Brett walked along she noticed some drops of blood on the floor that trailed deep into the side alley Brett looked around to see if she could see Dawson. There was no sign of her so Brett carried on walking. "Hello this is the paramedics is someone in need of medical assistance?" Brett shouted as she continued walking. Suddenly Brett noticed the droplets of blood had gotten bigger and as Brett turned a corner she saw a young black man holding his stomach. The man was laying in a pool of blood and was desperately trying to stay awake, it was evident that he'd been shot. "Hey Dawson I've" Brett started speaking into her radio but was suddenly cut off as a hand gun was thrust into the back of her head.

"Hands in the air or I'm blowing your fucking head off bitch" a male voice spoke. Reluctantly Sylvie obeyed this mans orders. Suddenly the man walked around and Brett noticed that he was wearing jeans trainers and an oversized black t-shirt along with a green bandana that coved his face Brett instantly assumed this was a gang shooting as they'd been briefed earlier in the day that there was a gang war going on. "Well what have we got here a little white bitch in my hood give me one good reason why I shouldn't pop you here and now along with that stupid motherfucker on the floor" the man coldly asked as Brett looked him right in the eyes.

Brett's heart was now racing as fast as a car as she stared right down the barrel of the hand gun. "This man needs medical treatment look I'm not a cop you can go seriously get out of here while you still can" Brett carefully spoke. Brett knew that this guy with the gun had already shot one man so they'd be no reason as to he wouldn't shoot her. Brett's radio suddenly crackled into life as Dawson was trying to get through to her.

"Yo Brett what was you saying only you cut me off" Dawson voice crackled.

Brett eyed the guy with the gun as he suddenly looked to the radio. "That's my partner if I don't reply she's going to know something's wrong" Brett desperately spoke.

The atmosphere was getting even more tense as the man with the gun pushed it right into Brett's head. "Give me that radio" the man ordered. Brett reluctantly lowered her hands down to unclip her black belt. "You think I'm stupid bitch" the man shouted which made Brett jump. "Take it off with one hand" the voice shouted. Brett unstrapped her belt and handed it to the man who then proceeded to stamp on it.

Gabriella Dawson was now starting to get extremely concerned about Brett as she couldn't get through to her Dawson ran as fast as she could back to the ambulance and pulled the doors open. "Brett!" Dawson cried as she looked inside "damn it where is she?" Dawson angrily spoke to herself. Suddenly Dawson remembered they'd split up. Dawson quickly took the alleyway that Brett had taken and suddenly Dawson saw the gunman talking to Brett, Dawson quickly jumped behind a bin and radioed for help. "This is ambulance 61 I need immediate police back up to my location my partner is being held hostage" Dawson quickly spoke.

"Rodger police units are inbound ten minutes" the controller replied.

Dawson cursed underneath her breath as she new she had a choice either wait for police assistance or deal with the situation herself. "Damn it I need backup now we don't have ten minutes" Dawson angrily whispered into her radio. Dawson knew either choice could cost hers and Brett's lives.
