*Another chapter is up so enjoy it! :)

Watch your back and be safe

One week had passed since the meeting at the precinct and nothing had happened. No weird incident in the streets involving patrol officers, no other little film, not even a little attack against the precinct. The Intelligence unit was still on alert but since Voight had told them not to do anything till he had all the information about the old case, they were just sitting and waiting except for Mouse who was trying to track down the white civic but the more he searched, the more he started to think that they were chasing a ghost.

"Guys, I'm really sorry but for once, I have to admit...I am lost. I've been trying to track down this fucking car all week long and I have nothing! '' he cried exasperated, slamming his hands on the desk.

Jay smirked. " Calm down Mouse. We didn't have anything either. All the phone calls we received since the diffusion of the description got us nowhere. What about the video? Did you found something that might help us figure out where it was recorded?"

"Oh right! About that, I just finished with it and I think I found something." the young tech turned his computer screen so the others could see. Look at the background.

"Yep and what are we supposed to be looking at?" asked Antonio, shrugging his shoulders.

"Well you see behind the head of the perp. There his a window and when I enlarged the view, I found something. I know where it was filmed actually. On Michigan Av, there are a few old warehouses. Some of them are abandoned. If you look closely, we can see what's on the other side of the street across the place where our suspects recorded their movie. It's Old St- Mary's Catholic church." explained Mouse.

Antonio looked at him. "You're a genius! You know that right!?"

Mouse smiled and suddenly jolted.

"I think I have an idea. There are a few police radar in this district. If I can just get into their systems, I might be able to see if there was a white civic in this area...and...BINGO! I GOT IT!" Mouse screamed ecstatic.

At the same time, Voight and Olinsky entered the room and looked at the young tech suspiciously. Mouse sat down on his chair and looked down. He had always been a little intimidated by his boss.

"Looks serious. Would you mind sharing?" asked Voight, looking at Mouse. Ruzek stood up and talked.

"Actually, Mouse found out where the video was recorded and he traced the car using the police radar from the street in the same area than the warehouse that was use in the film. Turns out that the car is there as we speak." explained the young detective.

Voight looked quite surprise by the young technician. He would never tell anybody but he was actually really proud of the young man. He looked around at his team.

"Alright! Everybody grab your coat. We are going to look into this. Be ready in ten." Voight said before taking the address Mouse had written on a peace of paper.

Ten minutes later, the team was downstairs with their vest on and their guns ready. They had the plan from the warehouse and they were looking at it. Roman and Burgess were also there in their uniforms listening carefully to what was being said.

"We need to be really careful about this one. We don't know anything about who they are or how much of them there is. From what we have so far, there are at least three suspects that were seen when there was the attack against the precinct. So Lindsay and Halstead, you are entering the front. Olinsky and Ruzek you are taking the backdoor and Antonio and me are going to enter by the last door on the side. Roman and Burgess you two are going to be there for back up. If something turns south, we are counting on you to take over. Is that clear for everybody?" asked Voight. Everyone nodded their heads in approval.

"Good. It's time to go. Everybody be safe! If you feel that something is wrong, you get out of there." and with that, each members of the unit entered their car with their partners and drove off to the location that Mouse had found.

Lindsay was driving as always and Jay was just looking at her. She saw him and smiled.

"What?" she asked.

"Nothing, I was just wondering when we were going to tell Hank about us. I mean, we are actually going to live together so that don't really leave us a choice." explained Jay with a smile playing on his lips.

Lindsay sighed. "I know that. It's just that I don't know how he is going to react. I mean, I'm pretty sure that he has some doubts but there is actually a big difference between him having doubts and treating you like an idiot and him knowing about us and killing you for being with me." she explained.

Jay laughed. He put a hand on her knee and smiled at her.

"How cute. You are actually scared for me. That's lovely." said Jay.

She looked at him for a second before taking her eyes back on the street.

"Lovely? That sounds weird coming from you." she laughed.

"I promise you that when this case is close, we are going to tell him together and I will stop him from killing you if he tries." she said seriously.

"It's a deal then." said Jay. "Are we there yet?" he asked when he saw that Ruzek and Olinsky car stopped in front of an old warehouse. It was dirty and the walls looked like they were made out of metal or something like that. There was rust in some places and the vegetation had started to install herself around it. Lindsay and Jay got out to join Ruzek and Olinsky. The group was soon all together and were ready to enter the building. It looked empty but they were being extra cautious since they knew how it had ended seventeen years ago and they didn't want the story to repeat herself. They all took position, their guns draw and waited for Voight signal before entering.

"Everyone in position. We are going in now!" said Voight in his radio and the team moved has they had been told.

The unit made their way into the warehouse. Ruzek and Olinsky looked around from where they had entered and had nothing.

"All clear" said Ruzek in the radio so the others could know that their part of the building was safe.

It was soon followed by Antonio's voice announcing that it was also clear on their side.

Than their was Burges voice on the radio.

"We found the car. A white honda civic with the plate starting by the letter Z. It's outside."

Voight looked at Antonio. At least now they had something to work with. He took his radio.

" Lindsay, Halstead" Is everything clear?" he waited for an answer.

Antonio looked at him worried. They hadn't heard any gunshot or anything.

"Lindsay, Hal..."

He was cut off by the sound of Lindsay's voice on the other side of the radio.

" Everybody get out. It's a trap! I repeat. We all need to evacuate, the place is rigged with explosives. Everybody out!"

Burgess and Roman who were already outside just looked and waited for the others to evacuate the building. They took of running when they saw Antonio and Voight get out and screaming at them to take cover. In a matter of seconds they heard a loud bang and felt the heat as the burning exploded and was engulfed with flames. It took a few minutes before someone moved. Voight and Roman were the first ones to get up. Roman helped Burgess up.

"You okay" he asked.

"Yes I'm fine. We were far enough of the blast." she responded. "We need to make sure that the others are alright."

The two patrol officers walked towards Voight and Antonio who looked to be unarmed.

"Thank god you two are okay" said Roman looking at them. "We are fine" added Burgess when she saw the silent question in Antonio's eyes.

"Where are the others? Did they made it out in time?" she asked.

Antonio shrugged. He took his radio and tried to join Olinsky and Ruzek.

"Ruzek, Olinsky, do you copy?" he tried. He let a few seconds pass before trying again.

Voight was anxiously waiting for any news on his missing team members. He had already asked for medical assistance and for the firefighters and he could hear the sirens coming closer and closer but no words on his team.

Antonio tried again.

"Olinsky, Ruzek, Do you copy?" he let out a sigh. "Halstead, Lindsay do you copy?"

"Antonio! We are outside. We made it outside before it blow off. I need some paramedics hear!"

Antonio recognised the voice.

"Olinsky? Are you okay? Is Adam alright?" he asked nervously.

"Me I'm fine. I just got some scrapes from flying debris. But Adam got a nasty bump on the head. He is unconscious." explained the older agent.

Voight looked at Antonio.

"Go! I'll send the paramedic as soon as they arrive. We still have no words on Halstead and Lindsay. Roman, you go with him. I'll stay with Burgess."

Roman and Antonio took off to go help Olinsky with Ruzek and to make sure that the two of them were in fact okay. Voight and Burgess looked at the burning warehouse anxiously. Voight was still trying to contact Lindsay and Halstead.

"Erin do you read me? Are you inside?"

Without any answers, Voight was considering entering the burning building but he wasn't even sure that his two agent were still in there. They could be out cold outside from the blast. The sight of the door in flames also told him that there was no way he could go in without getting hurt so he had to wait for the fire department to get hear but deep down inside he was scared. He was scared for Erin and for Halstead. He had let anyone believe that he disliked the young man but in reality he truly admired him. Not only he had been a ranger but he came back to become a hell of a good detective. Jay made him think of himself but in better. He knew that the man had his heart in a good place and that he would always walk a straight line. That's what made Jay a good cop.

He tried his radio again.

"Erin, Jay do you copy? Where the hell are you?"

His heart stopped when he heard something at the other end of the line.

"Hank!? It's Erin!"

"Erin! Are you okay? It's been nearly ten minutes!"

"Hank! We are inside. I'm with Jay. He's hurt. I don't know how bad."

"Okay Erin. Help is on the way. I can see the trucks. Hang on thigh. I promise everything is going to be alright!"

With those last words he ran towards the fire trucks and the ambulances that were coming their way. As soon as they came to a stop Hank started talking. It was Casey and Severide that came up to him.

"Voight!? What happened?" asked Severide.

"We had a lead on our case but when we entered the warehouse, Erin screamed to get out and the whole place blew up. You have to find them. They are still inside." explained Voight.

"Who's inside?" asked Casey

"It's Jay and Erin they came in from the front so they shouldn't be to far. And there's Adam. He's hurt. He is on the other side of the building with Olinsky and Roman."

"Okay. Stay back. We will get them out we promised. You have blood on your forehead, you need to get that checked out." said Casey to Voight. He turned around to call for the paramedics.

"Borelli, Brett. There is an injured agent on the other side of the building. Go attend to him." He signalled for another paramedics he didn't really knew to attend to Voight. He then turned to talk to Boden and Severide.

"We have two agents trapped inside. It' Lindsay and Halstead. Voight told me they are supposed to be near the front door."

Boden looked at his team.

"Alright. Dawson, Severide, Casey and Hermann you're going in. You find those detectives and you get out. This building could collapse at any moments." said Boden looking at the fire.
