The rest of Saturday and all of Sunday Jay spent time bonding with Casper. Jay decided that is best to start with teaching Casper simple commands before teaching him the tasks that Hailey and Will mentioned to help with his PTSD.

While trying to teach Casper simple commands such as sit, lay down, come, stay, heel, leave it, and no, Jay noticed that Casper listened to him well. "Good boy," Jay praises after Casper completed the command correctly.

Looking at the time, Jay guesses that Will is off work for the day unless an emergency came in at the end of his shift. "Do you want to go for a walk?" Jay asks Casper. Casper responds by running around excitedly in a circle, "I guess that's a yes," Jay tells himself.

Jay picks up his phone and calls Will as he goes to grab Casper's leash. Seeing his leash, Casper runs over to Jay.

"Hey, everything okay?" Jay hears his brother ask when he picks up.

"Yeah, everything is fine," Jay answers. "Are you done work for the day?"

"Yeah, why?"

"I was just going to take Casper for a walk and wanted to see if you wanted to meet up with Kohl?"

"Yeah, sounds good. Meet at Lincoln Park?" Will answers.

"Okay, see you there." Jay hangs up with Will before clipping the leash to Casper's collar, "Let's go Casper. We're going to see Uncle Will."

"Hey," Will greets as he and Kohl walk up to Jay and Casper.

"Hey."

"Here," Will says as he hands Jay a leash wrap.

"What is it?" Jay questions as examines the object, noting that it says do not distract service dog in training on both sides.

"It's a leash wrap," Will explains, "it goes around his leash. They're supposed to let people know he's a working dog and to not disturb him."

"Thanks," Jay tells his brother as he puts it around Casper's leash.

"So, is everything okay?" Will asks his brother.

"Yeah, why?"

"Because normally you don't ask to spend time together unless we're going to watch the game."

"I can't want to spend time with my brother?"

"No. You can, I just want to make sure you're okay. It's my job as your older brother."

"Isn't it my job to protect you? I mean, I'm the cop."

"You know what I mean. So how is it going with the dog."

"It's good. Casper is good."

"Are you going to start training him soon?"

"I started last night with basic commands. Once he gets the hang of those, I'll start with the ones that you and Hailey said I should teach him."

"How is he doing with those commands?"

"Good, he's good at listening. Catching on well."

"Yeah, I think Liam said something about how he had already started teaching him basic commands, something about hoping it would help find him a good home."

They walk in silence for a while before Jay brings up what he talked with Hailey about, "So, do you mind keeping this between the three of us?" he asks his brother.

"What?" Will is confused by the request.

"That I got Casper for the intent of a service dog. Between you, me, and Hailey," Jay elaborates, "I'll tell the team eventually, but right now I need time. For now, all they need to know is I got a dog."

"Okay. Whatever you feel is right. How was Casper last night?"

"He was good, slept in his cage."

Jay walks up the stairs to intelligence Monday morning, for the first time in a few weeks he made it in at a normal time. Having closed their latest case, Voight fills in his team on the next case that they have. "Alright guys, we got this case from violent crimes."

"Why did we get it from them?" asked Rojas.

"They've been working on it for three weeks and got nothing, so the higher-ups reassigned it."

"So what's the case?"

"A string of home invasions throughout Edison Park. The only connection is that they live in the neighborhood and all of the families have two children: a son and daughter. In three of the five invasions, the boy was the older child."

"Upton and Rojas I want you to reinterview the first two families; Halstead and Burgess the last three; Ruzek and Atwater I want you to gather all the information you can on these families to see if anything else connects them. Remember, nothing is too small a detail."

Upton and Rojas, and Halstead and Burgess both head out to talk with the families while Ruzek and Atwater started on the research side of the investigation.

"Mrs. Jacobs, I know you already spoke with the other detectives, but is there anything that you can think of?" Jay asks the wife of the most recent home invasion.

"I don't think so. Everything was so normal," she responds.

"Have there been anyone new coming into your house? Repairman, cable guy or anything like that?" Kim adds.

"No. Not recently."

"Recently?" Jay asks.

"We had someone come in, maybe three months ago to fix the internet," Mrs. Jacobs answers him.

"Okay, thank you for your time," Kim replies as she and Jay leave.

"So what do you think?' Jay asks as they get into the car.

"I think, if she's telling the truth there are no connections. But she could be hiding something, did you notice the way she hesitated?"

"Yeah," Jay paused, looking at the time, noting that he needs to let Casper out. "Do you mind if we make a detour? I need to take care of something."

Kim is hesitant to answer, "Are you okay?" she asks, knowing she might be overstepping.

"Yeah. Fine. It will only take ten minutes, fifteen max."

"Okay, do you need back up?"

"No, you can wait in the car."

Driving to his apartment, Kim begins to have an idea of where they are going. Having never been to his place, but knows the general neighborhood where he lives, Kim asks, "What are we doing in your neighborhood?"

"Ten minutes, just wait in the car," Jay tells her as he parks the car and gets out.

"Hey, Casper," Jay greets as he enters his bedroom going to the cage. Casper greets Jay excitedly, not used to being separated from his owner for hours at a time. "Come on, let's go outside," Jay speaks to Casper, noticing that he didn't have an accident in his cage, that he'd have to clean up before going back to work.

Jay clips on his leash before walking Casper out. Once outside, Jay encourages Casper to go to the bathroom. Praising him when he does go, Jay is about to take him back in when he hears his name being called.

"Jay," Kim calls, "when did you get a dog?"

"I thought I said to stay in the car," Jay answers annoyed, trying to hide the leash wrap.

"I was. Until I looked up and saw you with a dog."

"I got him Saturday," Jay answers.

"Were you going to tell us about him?" Kim asks, "What if you got shot and no one knew about him?"

"Hailey and Will know about him. They were with me when I got him."

"What's his name?" Kim asks as she puts her hand out for the dog to sniff.

"Casper."

"Like the ghost?"

"He's three months old and already had the name when I got him on Saturday. I didn't want to change his name and confuse him," Jay answers. "We should be getting back to the district. Let me take him back in and I'll meet you in the car.

Taking Casper back up takes little time, Jay gives him a treat before putting him back in the crate, promising to be back later in the afternoon to let him out again.

"So, what made you get a dog?" Kim asks when Jay returns to the car.

"Will knew a guy who's dog just had a litter of pups. He thought I could use the company."

"Were you going to keep him a secret?"

"I wasn't going to tell you guys per se, but if it came up I wasn't going to lie about him," Jay answers cryptically.

"Why?"

"You know that I like to keep my personal and work life separated."

"Okay," Kim gets the sense that Jay is starting to get annoyed with all the questions about his dog. "What do you think the others found out?" She asks changing the subject.

"Hopefully more than us," Jay answers as they pull up to the Twenty-First.
