"Erin? Erin?" Jay called, "Erin what's wrong?" There was no answer on the other end of the phone. Dread filled Jay's belly as he heard exploding glass in the background. "Erin?" He tried again. But there was still no answer. Jay tore out of the locker room, where he'd gone to call Erin in private, and into the bullpen. "Mouse, ping Erin's phone. Now! And send fire and rescue to her location," Jay barked.

His panic alerted the rest of the team.

Voight rushed out of his office. "What's going on? "

"I think Erin was just in a car accident."

"Let's go. Mouse text us her location," Voight demanded. Mouse nodded but was already typing franticly on his computer.

"I'll drive," Antonio offered and the three headed down the stairs, the rest of the team not far behind.

The accident site made Jay want to vomit. Erin's car sat half crumpled under the cab of a transport truck. Two other cars were pushed sideways in the road and pinned together. Fire trucks, cop cars and ambulances blocked the intersection and a dozen firefighters worked to free trapped motorists. Casey, Hermann, and Severide were currently trying to saw the roof off Erin's car. Brett had maneuvered her way into the backseat and was hunched up over Erin covering her with a protective blanket.

Jay, Voight and Antonio rushed to her car. "What's happening?" "How is she?" "What can we do?" They all spoke at once.

"She's pinned down. Unconscious but breathing. May not be able to lift her out without prying the dash off her leg. Not much you can do but stay out of the way for now," Severide quickly filled them in. Antonio wandered off.

"The driver?" Hank inquired.

Severide pointed to an ambulance across the intersection. "Not his fault. Some idiot on a bike jumped the light, truck had no where to go. He's shaken up pretty bad. But didn't seem too hurt."

Hank nodded.

Jay began scanning the intersection for the bike and its rider, rage battling with his anguish. He was gonna kill the idiot. Antoinio's hand came down on Jay's shoulder. Jay looked back at him and Antonio shook his head. "Didn't make it." He said quietly and nodded in the direction of the bike. It was bent around a concrete post. An ambulance crew was loading the rider's covered body onto a stretcher. Jay's eyes closed, he said a quick prayer for the riders family then turned back to watch 51 work on extracting Erin from her car.

As the seconds drew on Jay's distress grew. She had to be okay. There was no other option. He refused to believe she'd be anything but okay. The sounds around him grew quiet as he focused on this sole thought.

She had to be okay.

She would be okay.

He stood frozen unable to process the sight unfolding in front of him. Blurs of black and yellow jackets crossed in front of his eyes. Sparks flew like fireworks as saws cut through metal. Emergency lights flashed all around them. All Jay heard was his heart thudding in his ears.

Then the space in front of him filled. Jay blinked and focused on Chef Boden's features.

"Halstead, are you listening? I said you need to back up. That truck is going to catch fire any minute now," he said, as he gently pushed Jay back.

"No. No, you have to get her out," Jay demanded pushing back.

Boden held firm. "We're working as fast as we can but you need to step back and let us do our job."

Jay struggled to get past Boden but arms came around him in a bear hug, pulling him back, and another body stepped in to take the Chef's place so he could focus on the accident scene. "We got this Chef. We've got him." Ruzek assured the Chef.

"Come on Jay," Atwater bargained from behind while Jay tried to break out of his bear hug. "Let them do there job. She's gonna make it. You know she will."

No he didn't. He didn't know anything except the last thing he said to her was accusing her of not caring about him. Jay pushed out of Atwater's hold and turned away from his teammates. His hands ran through his hair as he tried to gain control. He couldn't break down.

Not now.

Not here.

Al came to stand beside him. "Hey," he said gently, placing a hand at his back. "Hey," he said again, forcing Jay to look at him. "Come on, keep it together. We don't know anything yet."

Jay took a breath and nodded. As he turned to check on the progress a whoosh sound caught his attention and the front of the truck went up in flames. Jay's heart went to his throat and he bolted forward. Ruzek and Atwater leaped in front of him. Jay yelled and tried to fight them off not hearing them at first but their voices finally broke through his panic.

"She's out! They got her out!"

Jay looked around franticly until his eyes spied Brett and Burelli loading Erin in the back of 61. Voight stalked from the ambulance towards him.

"Go with her. We'll meet you there." Jay stood, stunned for a moment. He'd assumed Voight would insist on riding with her. "Halstead, go. Now," Voight commanded. It was all Jay needed to hear. He nodded and rushed to the ambulance, climbing in beside Erin and taking her hand.

"How is she?" Jay needed something, anything.

"Her blood pressures dropping," Brett said too distracted by caring for Erin to offer him more. He watched helplessly as Brett manipulated tubes and needles and barked out information to Burelli. He knew enough to catch on that Brett though she was bleeding internally and that it was serious. He squeezed Erin's hand and brushed the hair that was caught on the oxygen mask back off her face. There was a cut on her forehead, her head had likely hit the steering wheel and he wondered if it was that which had knocked her out. His thumb stroked the sink above the cut wishing she would wake up and start arguing that she was fine and didn't need to go to the hospital.

Anything.

"Hang in there Erin. We're almost there," he tried to reassured himself as well as her.

When they entered the ED Maggie shouted orders for Erin to be taken to Bagdad and his stomach flipped again. He knew it was very serious now. He stood outside the exam room, arms crossed while Rhodes, Will and Choi buzzed around Erin. Jay tried to wrap his head around what was going on. Seeing her laying there, not responding to their probing, her stillness in the mist of the controlled chaos around her was incomprehensible. His tough as nails partner lay helpless and tiny while doctors and nurses probed, prodded and manipulated her.

Jay cringed. She'd freak if she knew what they were doing to her. No way would she stand for that many people in her personal space, the needles in her arms, the tube down her throat, the scissors cutting her clothes away so they could get at her injuries. He wanted to yell at them to back off, give her room, but he knew they were trying to help her. He knew every invasive touch was to try and save her life. His knees when weak at that thought and his vision blurred.

She had to be okay.

Warm hands pressed into his forearms. "Jay, you need to let them work. Come and sit down." Nat encouraged. He ignored her. He didn't want to sit. He wasn't letting Erin out of his sight. "Jay," she tried again. "Jay we need some paperwork filled out. Do you think you can help with that?" Nat tried a different angle.

He glanced down at her. She held a clipboard out to him. Reluctantly he took it and filled it in as fast as he could. But he didn't get far before Erin's gurney was being pushed past him, toward the elevators.

"What's happening?" he demanded.

Will came to his side. "She bleeding internally, they're going to operate to try and stop the bleeding. She may have some broken bones in the leg that was pinned down and we've also ordered a CT scan, she took a pretty nasty blow to the head. We need to see if any damage was done there."

"Is she going to be okay?" He looked his brother in the eye. He didn't need bullshit or Doctor speak right now.

"I think so yes," Will answered without wavering from his brother's stare. "But there are always risks Jay."

"Risks with what?" Voight demanded as he came up behind them, the rest of the team filling in behind. Will explained Erin's current condition then offered to take them all up to the waiting area. He promised to check in with any news. On his way out he grabbed his brother's arm.

"Jay she a strong, healthy woman. And Rhodes is a good surgeon. The odds of her pulling through this are high. Just think positive and try to stay calm," he tried to reassure Jay. Jay appreciated his brother's effort and nodded his thanks but he knew he'd have no calm until Erin was back at his side.

Watching his back.

Him watching hers.

Where she belonged.
