When Hailey woke up the next morning it was early, but she couldn't get back to sleep. She decided to take a shower, she still didn't feel well and hot showers always helped her feel better. She headed back to her room to get dressed and heard the shower go on again a few minutes later.

She took her time getting ready, she had nowhere to be and she wasn't exactly sure what was in store for her. By the time she headed into the kitchen, Will was already showered and dressed and was making eggs. She didn't see Jay, but she could hear the shower running again. Will glanced over his shoulder when she walked in.

"Are you hungry?" He asked. "There's enough scrambled eggs for you."

"I'm not really an egg person. They kind of make me feel nauseous, most dairy does." She said, and then frowned. "Is that a medical problem?"

He smiled. "You probably just have a food sensitivity."

"So, I'm not dying?" She grinned at him. "Is there coffee?"

"Yeah, over there, and I saw some of the cinnamon raison bread you and Jay both love so much." He said. "Wait, do you still like it?"

"Yes," she smiled, happy he remembered as she put a piece in the toaster. "But only when it's toasted."

"Only way to eat it, put some in for me, will yeah?" Jay said as he came into the kitchen to join his siblings. He grabbed a cup of coffee and leaned against the counter. "What are you doing today, Hails?"

She shrugged. "Not sure yet, I don't have class today."

"Do you want to come to work with me?" He asked.

Hailey frowned. "Is that even allowed?"

"Sure, we have people do ride-alongs all the time." He said. "Come on, it will be fun."

"I have the day shift, we could get dinner tonight?" Will said.

Hailey looked at both of them, slightly suspicious. "Do you two think I can't stay alone?"

"I think you might be a little too good at being alone," Jay said. "So, do you want to come or not?"

"Yeah, I guess." She said as the toaster popped. "What could it hurt?"

"I work in a special unit now, though," he said as he handed her the peanut butter. "Things can get a little intense."

"That's an understatement," Will said. "They work the worst cases."

"What kind of cases?" Hailey asked.

Jay stepped away when he phone started ringing, but he wasn't gone long. "Time sensitive cases," he answered. "Come on, we have to go."

Hailey grabbed her bag and grinned at her brother. "Bye, Will."

"Bye Hails." He smiled.

Hailey followed Jay into the district. She tried not to look around at the people too much. She had a feeling no one knew about her and she didn't want to see the looks of confusion thrown at her. He headed up the stairs with a gate on the landing. He slipped his hand onto the monitor and she just looked at him, clearly unaware what it is her brother actually does.

He grinned at her as he opened the gate. "Welcome to the Intelligence Unit, Hails." He said.

"Intelligence?" She questioned as she walked up the stairs. "I've heard about this unit in class."

"Hopefully all good things," Lindsay said. "I'm Erin."

"Hailey," she said as she shook her hand.

"Erin is my partner," Jay said before he looked to Voight who was standing in the doorway of his office. "Hang on a second."

Hailey watched him go and then turned to Lindsay. "I'm not actually supposed to be here, am I?"

"Voight won't mind, he just doesn't like to be blindsided." She smiled as some of the guys came up the stairs. "Hey guys, this is Jay's sister, Hailey."

"Well, it's nice to finally meet the third member of the Halstead trio," Antonio said.

"Don't be intimidated by these boys, Hailey," Lindsay said as she pointed them out. "Antonio, Al, Adam, and Kevin."

"So much for the alliteration trend you had going there," Hailey said.

"I like to mix things up," Kevin said. "But that's probably why we go by last names around here."

"So, here's what we've got so far from the school bomb incident this morning," Mouse said, coming up the stairs with a file.

"Mouse?" Hailey asked.

"Hailey?" He turned at the sound of her voice, surprised to see her. He dropped the file on the nearest desk and opened his arms to her.

"I haven't seen you in forever," she mumbled into his chest, a huge smile on her face.

"I know," he said softly. "How are you?"

"Good," she said as they separated. "You?"

"I'm good," he nodded as he turned to Jay who was coming out of Voight's office. He frowned at his frowned as he pointed to Hailey. "I just want to check in on her? You couldn't tell me she was coming?"

"I didn't know if she would come," he said with a smile. "And I did want to check in when I asked you to look her up."

"So, that's how you found Scott's place." Hailey said.

"Is Scott the boyfriend?" Lindsay asked. "Poor guy."

"Shut up," Jay said with a grin as Voight came closer. "Hailey, this is Sargent Voight, Sarge, this is my sister, Hailey."

Voight nodded. "Nice to meet you Hailey."

"You too." She smiled slightly.

"Everything that's said in this room is confidential." He said as she nodded. "Alright, what do we know?"

Hailey listened to the case, to the questions asked, and to how the team put things together. She had never seen it done before and she was kind of amazed. It wasn't safe for her to actually ride along with her brother while he worked, so she stayed behind when they went out and caught up with Mouse.

When the team did come back, they had a kid with them and Hailey watched the exchange between him and her brother while she stood behind the two way mirror. In the moments when Jay was able to connect with him and get him to open up about the traumatic experience he went through, Hailey was reminded of the kind of person her brother really was.

Lindsay was watching Hailey listen to the conversation. "He talked about you before," she said.

"Really?" She asked.

"He has this picture of the three of you in his desk. I saw it once and he went on and on about his brother the surgeon and his little sister who's going to change the world." She said.

Hailey frowned. "Did he tell you we haven't spoken in a year?" She said as she started through the glass. "I used to talk to him every week or so, but then he started missing my calls and he'd take days to reply to a simple text. It got to the point where I'd see how long it would take him to reach out to me if I didn't initiate the conversation. Eventually I just gave up, the rejection of waiting around for him to get back to me was just too painful."

"From the way he talked about you," Lindsay shook her head. "You'd think you were his whole world."

Lindsay looked at Voight, who nodded for her to step out. "Listen, Hailey, I have this thing about helping out kids so they get a second chance." He explained. "I know what happened with you and your Dad, and I know you're still upset with Jay for not being there and I don't blame you. I want to help you, so anything I can do, you let me know."

Hailey was quiet for a moment. "Did you know about me?"

"I found out when your brother Will came to in," he said. "Jay's good police, one of the best, but he's pretty private about his personal life. Sometimes in this job you have to put a little distance between you and those you love most."

OOOOO

Jay came home late that night. Will had picked Hailey up from the district, but Jay needed to wrap things up. When he finally got home, he found Hailey on the couch watching Netflix. He sighed as he sat down on the couch with her. It had been a long day and he was exhausted, but he needed to check in with her.

"Where's Will?" He asked.

"He got called in, some emergency," she said. "Left about an hour ago."

"Do you have class tomorrow?" He asked.

"Yeah, at eleven."

Jay frowned as he glanced at his watch. "Little late isn't it?"

"I can't sleep."

"Will is working on renewing that prescription." He said.

"It's not that," she said.

"Then, what is it?" He asked.

She looked at him, she did want to tell him, but she wasn't sure how to. "Did you tell Dad I was here?"

"Will told him you were staying with us, yeah," he said. He tilted his head slightly, trying to get her to make eye contact. "He's not going to hurt you again."

"You don't know that," she mumbled. "He doesn't even know that."

"What happened that night anyway?"

"Which time?" She looked at him. "The first time he thought I was her, he grabbed my arm so hard I was sure he'd break it. He wouldn't let go, not matter how hard I tried to pull away or tell him that she was gone. The second time he was passed out downstairs on the couch and I swear I thought he was dead. I woke him up and I tried to help him get up but he pushed me and I fell into the side of that old wooden coffee table. And then the third time, the last time, I woke up to one of his drunken rampages. I used to hide his keys, but he wanted to visit her grave, even though it was the middle of the night. I tried to get him to go to bed, but he fought me and we were on the stairs and I fell."

"Down the stairs?" Jay said. "Hailey, he could have killed you."

"He's not some horrible person, Jay. He just can't live without her." She said. "But I couldn't live with him anymore."

"I wish you would have called me, or Will." He said. "I'm always going to be here for you, and I'm sorry if I ever made you feel like you couldn't come to me."

"Thanks," she nodded. "I'm going to stay, if you still want me to."

"Yeah?" He asked. "What changed your mind?"

"You did," she said. "I used to think you went to war and you left my brother over there, but watching you today with that kid proved that you're still who I remember."
