"How are you feeling?" Hailey asks Jay when he walks into the breakroom of the intelligence bullpen almost a week after the day she forced him to go home.

"Better. Still coughing and still a bit tired, but Will said that it would take a couple more weeks for those to go away," he tells her, voice still off.

"And your fever?" Hailey asks raising her hand to his neck.

"Gone."

"You still feel a little warm," Hailey tells him.

"Thanks for the soup, it was good," Jay tells her trying changing the subject. "You still come over for Casper's training tonight? I disinfected the whole apartment," he tells her.

"Yeah, I wanted to talk with you about that," Hailey starts.

"What's up?" Jay asks worriedly.

"Nothing bad. When you were sick last week, Will and I were talking, just trying to figure out how the training would work for these other tasks. Will told me that he had been talking with Ethan since he told us about this and that he had been talking to some other vets. Turns out that he has a friend that volunteers at an organization that trains service dogs. He said that he can connect us so we can see how to train the other tasks. We would still be doing the training on our own, but he can show us what we need to do," Hailey tells him.

"Okay, sounds good," Jay agrees.

"Let Will know so he can talk to Ethan," Hailey tells him as she walks out of the breakroom, leaving Jay by himself.

Jay pulls out his phone to call his brother before the rest of his team gets in. "Do you have a minute?" he asks when Will picks up his phone.

"Yeah, are you okay? You still don't sound great," Will asks.

"Yeah, I'm fine. Hailey mentioned how you two were talking about Casper's training," Jay starts.

"She told you about Ethan's friend?"

"Yeah."

"What do you think?"

"Would it really help with training Casper?"

"It would help with giving us an idea of how to train him," Will answers.

"Okay."

"'Okay'?"

"Yeah, okay," Jay reaffirms.

"Okay, I'll talk to Ethan."

Before Jay can say anything else, Ruzek appears in the doorway of the breakroom, "Jay, we got a lead."

"I gotta go," Jay tells his brother before hanging up. Seconds later he gets a text from his brother, I will let you what Ethan said tonight.

Jay goes back into the bullpen to find out what their next move is. "Halstead and Upton, check out the aunt's place," Voight instructs. "And Upton, fill him in on the way."

The two detectives of the unit go to the parking lot, "So what's the case?" Jay asks as they are getting into the car.

"Home invasion. The whole family was murdered except for a teenaged girl who was sleeping over at her friend's house. She came home the next morning to find her family dead. The neighbor called 911 when she heard the girl's screams," Hailey fills him in.

Jay sighs hearing this.

"You okay?" Hailey asks.

"Yeah," Jay breathes.

"Some first day to come back to," Hailey comments.

"Do you want me to pick up for dinner tonight?" Hailey asks as they are leaving for the day.

"You pick," Jay tells her. "I'm still not that hungry," he adds when Hailey gives him a look.

"You have to eat," Hailey reminds him.

"I will," Jay promises as they reach their cars.

"Hey, boy," Jay greets when he gets home. Casper greets him excitedly, as he got used to Jay being home with him, when he walks through the door. "Come on, let's go out," Jay tells him as he clips on Casper's leash.

Casper happily walks around before doing what he needs to. Casper tries to lead Jay to go for a walk before he is stopped, "Not tonight," Jay tells the dog before leading him back inside.

Once inside, Jay gives Casper his dinner before going to find something to watch on the television. When Casper is done, he makes his way over to Jay and lays by his feet.

Jay dozes off on the couch and only wakes up when he hears Hailey knocking on his door. "Hey," he opens the door to let her in.

"Hey, you look tired," she comments going to his kitchen.

"Thanks," Jay replies sarcastically.

"We don't have to do this tonight-" Hailey tries to tell him.

"No, we lost a week. I want to get back into the swing of things," Jay argues.

"Okay, if you're sure."

"I am. What did you bring?"

"For Will and me, pizza. For you, I made more soup," Hailey answers.

"You didn't have to."

"You said you weren't hungry and I doubt that you would feel up to greasy pizza."

Before Jay can reply, they are interrupted by Will knocking at the door. Jay opens the door for him.

"Hey, sorry I'm late. Got held up with the paperwork."

"You're good. I brought pizza," Hailey tells him.

"You're amazing," Will states as he grabs a slice.

Hailey shakes her head and grabs plates for herself and Will, and a bowl and spoon for Jay.

"What did Ethan say?" Jay asks as they are eating their dinner.

"He talked to his friend, Nate, who works with K9s for Warriors, and said that Nate has a class Saturday morning, but he can stay after and he can work with you in the afternoon."

"Okay. Are you guys coming too?"

"Is that okay with you?" Will asks.

"We'll do what you're comfortable with," Hailey adds at the same time.

"I want you guys there."

Once the three finish their dinner they go out to his living room to work with Casper. "So we're going to keep working on having Casper wake you up. Jay down on the couch and see if Casper will lay on you."

Jay lays down, but Casper needs to be guided on what to do. Hailey can see that Jay is worried, "Hey, it's okay. This is only the second day we're doing this step," she reassures him, knowing he is thinking that it is his fault since they lost a week.

"Let's do it again," Will suggests. "Casper. Come here."

The three work with Casper until they start to lose Jay around ten. "Jay let's call it a night," Hailey suggests when she notices Jay starting to drift off on her.

"I'm good," he tells her.

"Jay, you're still recovering," Will reminds him. "It is getting late. We can pick this up next time."

Together, the two of them manage to convince Jay that they've done enough for one night before leaving.

Late Saturday morning, Will and Hailey meet at Jay's place so they can drive to the training facility in one car.

When Jay comes down with Casper, the three decide to let Will drive as he had the address. Hailey sits in the front to let Jay sit with Casper in the back.

"So, where are we going exactly?" Jay asks as he scratches Casper's head.

"K9s for Vets has a training facility in Cicero," Will tells him.

"K9s for Vets?"

"It's an organization that pairs service dogs with veterans," Hailey tells him. "I was looking in to before Casper and self-training. But their organization requires a three week, twenty-four-seven on-ground training program. Figured you wouldn't go for that," she adds.

"You're right I wouldn't," Jay verifies before turning to Will. "Cicero is less than half an hour. Why leave so early?"

"I didn't want to be late, in case there were problems getting a start."

"And now we're a little more than an hour early. What are we going to do now?" Jay adds.

"We can get lunch," Will suggests.

"Will, it's miserable out," Jay tells him.

"Jay, in Illinois the same laws that apply to service dogs apply to service dogs in training. You can take Casper in with you," Hailey tells him.

"What if people ask questions?" Jay asks anxiously.

"Jay, breathe," Will orders. "There are only two questions that people are allowed to ask someone with a service dog. The first one is: is this a service dog required because of a disability? And the second one is: what work or task has the dog been trained to perform? Anything else is illegal," Will tells Jay.

"I don't have a disability," Jay argues.

"Your PTSD is a disability. But it's not who you are," Hailey tells him.

"We can go in somewhere or we can find a drive-through and eat in the car," Will tells him.

"Okay, we can try," Jay declares.

Will pulls into the parking lot of a small diner. They get out of the car and walk into the diner to be greeted by a young woman, who looks like she is in high school.

"Three?" she asks before noticing Casper. "Sir, dogs are not allowed."

"He's a service dog in training," Hailey tells her, seeing that Jay isn't saying anything.

"Service dog? He doesn't look disabled," she ignorantly states.

The three are shocked by her statement, but before any of them can say something a waiter walks over to them. "Jenny," he calls out. "ADA mandates that service animals are allowed in. Without question," he gives her a pointed look.

Jenny takes the hint and walks away, "I'm sorry about her, please don't judge the diner because of her."

"Thanks," Will is appreciative of the Hispanic man.

"Would you like a booth or a table?" he asks the group.

The three look at each other, "Jay, what is easiest for you with Casper?" Hailey asks.

"Probably table."

"Okay, follow me." He leads them over to a table that has plenty of room for Casper underneath. After taking their order of drinks, he asks, "Would you like a bowl of water for your dog?"

"Thanks," Jay speaks, shocked.

When he brings back their drinks he gives Jay the bowl of water to give to Casper, not wanting to distract the service dog.

Their lunch goes better than Jay thought it would, the waitress had been the only issue. There were a few other guests in the diner, but none caused any problems. Some cast short glances, but there were no comments.

When they go to leave, Will stops to talk with the man who helped them. "Thanks, for not making a scene like with that girl."

"Don't thank me for that. She is just uneducated," he explains.

"Still it means a lot to me that a stranger would defend my brother," Will elaborates before catching up with his brother and Hailey.

"Next stop, K9s for Vets training facility," Will announces when they are all in the car.
