"Jay," Hailey calls while knocking on his apartment door. Getting impatient with her partner, Hailey uses her emergency key to get into his apartment, glad for once that Voight made them trade keys with their partners after Kevin was kidnapped. Opening the door, with her gun drawn, Hailey looks around the apartment. Nothing seems out of place, albeit messier than what her partner's normal standard of clean is. As she makes her way to his bedroom, she can hear a strangled cry coming from Jay's room.

Heart dropping, Hailey opens his door to see Jay tossing and turning, tangled in his sheets, caught in a nightmare. Remembering how Adam told her about the time he tried to wake Jay and almost got punched in the face, so she finds a pillow that is laying on the floor and throws it at him.

Jay jolts up, feeling the pillow hit him. "Hailey?" he questions, "What are you doing here?" he asks when he realizes she is in the doorway to his room.

"I used the key. You weren't answering your phone and I was knocking on your door for ten minutes. I got worried."

"Sorry," Jay apologizes remembering that Hailey was giving him a ride since his truck was in the shop for an inspection, "Give me fifteen minutes."

"Jay, we're going to be late."

"Ten, help yourself to coffee," Jay tells her, trying to get on her good side by offering coffee.

Hailey goes to raid his kitchen for coffee while Jay goes to take a shower.

Ten minutes later, Jay is ready and Hailey is happy with her coffee and hands Jay a cup to go.

"So… have you been sleeping okay?" Hailey asks Jay once they are in the car.

"Fine."

"How have your meetings been going?"

"Good, helpful."

"You know you can talk to me about anything, right?"

"I know," Jay answers before looking out the window hoping that she takes the hint to end the conversation.

Walking into the bullpen, the pair are the last to arrive. "Halstead, Upton. You're cutting it close.

"Sorry, Sarge," the two reply in unison.

"Now that everyone's here," Voight continues, "This is José Martinez, second in command of a rising gang, responsible for the bad dope that's been hitting the streets. Nobody seems to know who is running the show. Contact your CIs and see if you can get any information on this gang."

The unit does as their told, Hailey keeping an eye on Jay. Even if they are not partners at the moment, Hailey is always going to have his back. He has open up to her, telling her things that not even his brother or Erin know. Since waking him up from what seemed to be a nightmare this morning, Hailey doesn't believe that he is as fine as he claims to be.

Looking over at Jay, she can't help but notice his appearance. To everyone else, it may just seem like he is tired, but to someone who knows him, there is more to bags under his eyes than just being tired and there is a bit of a haunted look in his eyes.

Hailey makes a mental note to talk to Will and see if there's anything they can do for the younger Halstead brother.

"You guys going to hit Molly's with us?" Kim asks the two detectives at the end of the day.

Jay and Hailey look at each other before answering, "I'm taking Jay to get his truck and then I'll meet you guys," Hailey tells her.

"I'm going to pass," Jay tells them.

"Okay," Kim answers. "everything okay?"

"Yeah, just tired." With that answer, the officers of the unit head out leaving the two detectives.

"You sure you're good?" Hailey asks Jay, "I can skip Molly's if you need to do our thing."

"I'm fine, really. Just tired."

"Okay, let's get your truck." The two head out to the parking lot and get into Hailey's car. The car ride is silent as she drives to the auto-shop where Jay's truck is at, dropping him off. "Call me if you need anything," Hailey tells him as he is getting out of her car,

Jay acknowledges her with a nod of the head. Figuring that's all she will get from Jay at the moment, she leaves to meet up with everyone at Molly's.

"Hailey," Kim calls when she sees her entering the bar.

"Hey, guys. What'd I miss?"

"Nothing much. Just Kev and Adam trying to hit on girls and failing," Vanessa answers.

Just as Hailey was about to make a dig at the two guys, she sees a familiar red-head walk into the bar with his co-workers, "I'll be right back," the tells her team.

Standing up she walks over to the doctor, "Hey, Will. Got a second?"

"Sure. What's up?"

"I'm worried about Jay. I think his PTSD is getting worse. Has he talked to you at all?"

"No, he hasn't. He's not exactly open with me. Maybe go to Voight? Can't he force Jay into therapy?"

"I could, but I don't want to lose the progress that I've made with him."

"Maybe if he could talk to someone that can't judge him," Ethan chimes in.

"I wouldn't judge him," Hailey defends herself.

"But he might think you would. I got a parrot for my PTSD, it helped. I can talk to it and it doesn't even know what I'm talking about."

"Actually, that's not a bad idea, Hailey," Will tells her. "When I was staying with Jay, he got along well with Kohl. I saw him talking with him when he thought I wasn't looking."

"So, you're saying I should convince him to get a pet? That's not going to happen with the hours we work."

"There are actually some non-profit programs, that pair vets with PTSD service dogs."

"Jay doesn't need a service dog," Hailey argues.

"It's not what you think. The dogs are trained to do different things depending on the need of the handler. They can distract if they are getting agitated, or they can wake them up from nightmares, there are also some that are trained to get their handler out of crowded spaces," Ethan tells her.

"It sounds like a good idea, Jay always had a soft spot for dogs growing up. We weren't allowed to have one, but Jay always loved dogs," Will adds.

"Look into the programs, there are a few that have local bases," Ethan tells her.

"I'll look into it if you guys think it will help him."

"It's worth a shot," Will answers, "The worse thing that happens is that he doesn't get paired with a dog."

"I'll look into it later this week. Thanks, guys," Hailey thanks them before going back to the intelligence gang.

"What was that about?" Adam asks.

"I just had to ask Will something," Hailey answers, not wanting to give away her conversation about her partner that she had with his brother, while also making a mental note to look up the organizations that Ethan was talking about.
