When they announced they would move him to the district, Will, didn't imagine it that way. The break room had been transformed into a medical one consisting of a hospital bed, a monitor and a ton of medical equipment. Before they arrived in, it had been disinfested by a skilled team so they would avoid any infection that could deteriorate Jay's condition. Connor was there most of the time, the whole Intelligence was present assisting the doctors and investigating the case.

"How are you holding up?" Platt inserted the room, holding a cup of coffee, handing it for the older Halstead.

"Good. Tired,"

"How is he doing?"

"The same since we brought him here. Out of it." Will sighed. "It's like he doesn't want to wake up, like he is giving up. I know he went through a lot that day but I can't lose him."

"You won't." Trudy rubbed his back as he buried head in his arms.

He looked at his surroundings one more time. How could he agree moving him? What if he needed surgery? What if he coded and they wouldn't bring him back in time? Or to take him to Med's ICU? Will's thoughts were interrupted by a whispering. His name was called a couple of times.

"Jay? Hey buddy, you are okay, you are okay," Will immediately grabbed his stethoscope from the counter checking his brother's lungs and heart. Jay flinched a little at its coldness but he relaxed in no time.

"Will." He sounded helpless like this was his last minute on Earth.

"Your saturation is normal, your BP is 130/70, your pulse is a little higher but okay, what's going on little brother?"

"Will…" Jay removed the oxygen mask from his face. "Hurts."

"Where does it hurt?"

"My side."

Removing the white sheets and raising the gown a little, he did not notice anything out of the ordinary. The gauze was still white with some red stains on it, however there was no indication of an infection.

"It's okay, everything's fine. Just breathe, breathe."

As his pulse seemed to decrease a little, Will, patted his brother on the shoulder.

"Where are we?" The latter asked, observing his surroundings. "Why are we in the district?" He coughed a little.

"It's a long story. I'll explain everything but doesn't freak out."

Starting from the wrong diagnose concluding to the criminal's break-in, Will, left Jay startled. He was trying hard to process the events of the past few days but couldn't remember much.

"I wanna help too." Making a move to get out of the bed, he gasped.

"Whoa, take it easy. You are in no condition to move yet." The doctor rushed to his side pushing him back gently.

"They tried to kill us, to kill Natalie. I have to take them down."

"Natalie is safe at Med. There are cops there."

"I need to save us."

Will raised his hands in surrender. "This is why I didn't tell you anything in the first place."

Jay sighed. His eyelids were really heavy and could not keep them open.

"Come on, get some sleep. Connor is going to be here in a while to check on you."

He lost the fight with himself and eventually fell asleep.

"Any news?" Will exited the room as soon as the team returned to the 21st.

"Nothing. The man we got, he won't talk. We have to no clue of where Halen and Seals could have been. For now, we know, that a whole family is involved in this case. Not just those three people." Voight punched the whiteboard hard before walking in his office.

"What about Jay?" Hailey asked approaching the young doctor.

"He woke up a while ago, I told him everything."

"Let me guess… He wanted to take part in this, right?"

He nodded.

Hailey smiled and moved to her office.

Looking through files, CIs, criminal records none of them could trace anything. Until that afternoon. That afternoon.

"Jay, I know you are awake, open your eyes for me." Rhodes talked to him softly.

He acted like a baby, he was aware of that but he was stubborn that he wouldn't obey his doctor's orders until they let him participate in the investigation.

"Jay, I need to check you out. Open your eyes."

"No… No… No…" He murmured.

"Fine. I can sit here all day." Connor sat next to his, crossing his arms.

Jay heard the break room door opening and his Sergeant whispering something to the doctor, however, he couldn't figure out his words. After a lot of effort, his eyes cracked opened taking a peek at Voight's worried expression.

"Is something wrong?" He asked sitting up a little.

Voight shook his head but he didn't speak. Quiet Hank meant, tragic news.

"We have two more names on our suspects. Helen Simmons and Jake Simmons. Twins. Do the names sound familiar to you?"

Jay had heard those names before; he was sure of that.

"Have you found them?"

"No, we only have their older brother, Josh in custody. The guy who almost killed you." It was difficult for Voight to remember. The moment he ran into his officer's room and saw him fighting for his life, the moment he passed out, the moment he almost died in his arms again when they moved him.

"I would like to talk to him." Jay insisted.

"For the last time, you are here so we can protect you."

"I am a detective and I have the right to know all the clues in this case." His body jumped a little on the bed, causing him to fall back in pain.

"There's a difference between a detective and an injured detective. You are off until further notice." The big boss made its decision.

Jay frowned and laid back down, holding his incision tight. "Fine. Then get me out of here. I am going to be fine at Med, I request to be transferred immediately.

Shaking his head, Voight left the room banging at the door.

Being unable to assist with the investigation, the younger Halstead boiled inside him. He felt useless, he had totally lost his independence, his abilities, he felt like a part of himself had been erased from this world. Staring at the IV lines connected to his arms, he remained silent completely ignoring the presence of his friend and doctor, moreover of his brother´s who had inserted the break room, minutes earlier. His mind traveled back to the past, to the moment he first met Helen and Jake Simmons.

¨Jay? Are you with us?" A familiar voice asked.

"Yeah, yeah." He blinked twice as he was snapped out of his thoughts.

"Connor needs to examine you."

He didn't say a word. Just allowed his friend to touch his body.

The view from the terrace of the building never seemed so beautiful. The sun had almost disappeared among the clouds, covering the form of Hailey Upton who was drinking her beer. Her blue eyes had tears on them, tears ready to fall at any moment. She took small sips as she inhaled and exhaled slowly.

"What are you doing up here?"

She turned back and watched as her boyfriend joined in. "Hey, Adam. Nothing. I was just thinking. This whole situation is so messed up. We have a friend downstairs fighting for his life and a suspect who won't talk. How worse can things go?"

"I know Hailey." He crossed his left arm around his waist. "I feel awful too. We haven't slept in days and we haven't managed anything yet."

"I just wish he listened. When Voight took him off the case, I wish he never went after the man who killed his father." A tear run down her cheek.

"There is no way to change the past but hey, we can change the future. Jay needs to know that we will be there for him, no matter what, even if the world is against him, we will be there."

The woman was amazed by his truthful words.

"I guess you're right. Did you find anything on those twins?"

"I have actually. Dawson and I found an address, we're going to arrest them in the morning. We will surprise them."

She nodded and smiled. One of those smiles that Ruzek loved seeing. Giving her a kiss, he stood up. "I am going back to the office, are you coming."

"Yeah, let's go."

The two of them descended the stairs and marched to the stairs leading up to Intelligence being startled when they faced Will yelling at Voight in his office. The rest of the team were intense too, with Antonio leaning to the whiteboard, Kevin talking to the phone and Kim pacing back and forth.

"What happened?" Hailey asked worriedly looking toward the break room.

"Jay. We lost him." Kim announced.

"What do you mean we lost him?" Adam asked supporting his girlfriend.

"He is not here. He was probably kidnapped."
