Will wakes up later that morning to find that Jay had moved in his sleep to be pressed against him. Will reaches out carefully for his phone to turn off the alarm, not wanting to wake Jay when he looks so peaceful after the night he had.

Looking down at Jay, Will is reminded of all the times that Jay had climbed into bed with him when they were kids after he had a nightmare. Being the older brother, Will always felt like he was the protector. He had to protect Jay from their father and from their peers at school. Neither of them fit in at their school because of the social class and neighborhood that they came from, but Will always felt that Jay got the worse of it because of his size.

The Jay that came back from Afghanistan was a shell of who his brother was. He was still the kind, caring, compassionate person, but he now had a haunted look in his eye that always seemed to be there. He grew distant and refused to let Will in like he had growing up. Will always had a hunch that it was because of what Jay saw when he was over sees and not being able to be home when their mother died; that he was in some way protecting himself from being hurt again.

And then came Erin Lindsay. Seeing her brought back some of the old Jay; he no longer looked haunted twenty-four-seven, but he was still hiding many demons. When she left, he could see the change in his brother. Will always had a hunch that his brother had some type of abandonment issues and her leaving only solidified it. After she left, Will could see his brother spiraling; refusing to get or accept help, Will watched helplessly as his baby brother was in a self-destructive path. Will was caught between wanting to help and being pushed away.

Eventually, Jay began accept help from his new partner, Hailey Upton. Initially unsure of his new partner, something changed to make Jay open up to her. Slowly, Will began to see the old Jay making appearances. He started to make progress with his PTSD thanks to Hailey. Will had hoped that Jay would have opened up to him, but as long as he sees his brother getting the help he needs and starting to go back to his old-self, Will's not going to complain.

Looking at the time, Will decides he can let Jay sleep a little more before he has to wake up. He carefully gets out of bed, so not to wake him. "Casper," Will whispers. Hearing his name the puppy looks up. "Come on, lay with your dad," he tells the dog while helping him onto the bed where he curls up against Jay.

Will gets ready for the day before making breakfast burritos for the two of them. After wrapping up two for each of them he goes to wake Jay.

Walking into his bedroom, he sees both of them still asleep with Jay's hand on top of Casper's head. "Hey, Bud. You need to get up if you plan on taking Casper home before work."

"Okay," Jay mumbles half awake. "Wait how did he get up here?" Jay asks confused.

"I put him up there when I got out."

"Okay."

"Come on. I let you sleep in, so you can't lounge around."

"Okay, I'm up. I'm up. What time do you have to be at Med?"

"Not until ten. Come on I made breakfast burritos."

"Okay, I'm going to take Casper out real quick first," Jay lets Will know.

"Okay."

"Come on Casper," Jay calls, helping the dog off of the bed. Jay throws on his shoes and then puts on Casper's leash to take him out.

"Casper, let's go back in," he tells the dog once he goes, "we have to hurry today."

"Jay," Will calls when he walks back in with Casper. "So, there's a two week wait to get in new people-"

"I don't want to mess up his shots," Jay interrupts worried about Casper.

"I know. I'm going to call today and see if I can get you in next week."

"Okay, thanks. For, well for everything."

"I'm doing this because I'm your brother and I just want you to be okay."

"I love you too," Jay replies. "I need to get going if I want to get to work on time and feed Casper."

"Okay, I'll text you when I know. Be careful."

"Always."

Jay puts his breakfast in the cup holders as Casper was demanding some head rubs on the way home.

When they get home, Jay throws his food in the microwave to heat his breakfast while he is feeding Casper. Casper gulps down his food, not used to waiting so long to be fed. Jay is able to eat his first breakfast burrito at home before putting Casper in his cage so he can go to work.

Jay eats his second one on the way to work, hoping he won't be late. True to the Halstead luck, Jay hits the morning traffic that he normally manages to avoid.

Rushing into the bullpen when he gets to the district, the first thing he hears from his sergeant is, "You're late Halstead!"

"Sorry, Sarge," Jay apologizes. Not looking at the rest of his team.

Hailey gives Jay a look asking, are you okay? He nods his head, body language saying that he will explain later.

"Halstead, since you were late, you can go downtown and track down the surveillance footage. Take Hailey with you, maybe she can keep you in line."

The two walk to his truck in silence. "So, is everything okay?" Hailey asks when they are in the privacy of his truck.

"Yeah, sorry Voight made you come with me," Jay apologizes, feeling guilty that she has to tag along on the boring trip.

"Hey, don't apologize," she gently reminds him. "How's Casper?" she tries to change the subject.

"He's good," Jay happily answers. "I was actually late because I had to take him home and feed him then I hit the morning traffic. We crashed at Will's last night."

"How was that? Have a good time?"

"It was okay," Jay hesitates.

"Did something happen?"

"Will and I went over your list. It was late so he made me stay the night and I had a nightmare. He had to wake me. He's also going to try to get Casper in next week for his next round of shots."

"Hey, you know Will's not going to judge you, right?"

"I know. It's just embarrassing. I shouldn't be having these nightmares and my brother shouldn't have to be waking me."

Jay pulls into the center before Hailey can answer. They spent ten minutes tracking down the person who can get them the footage before they are able to go back to the district.

On the drive back Jay gets a call on his personal cell. Hailey answers it and puts it on speaker after seeing that it is Will.

"Hey, Will," Jay greets.

"Hey, you busy?"

"Not really. We're driving back to the district."

"We?"

"Hailey's with me."

"Oh, hi Hailey."

"Hey Will."

"So what did you call for?" Jay asks getting them back on track.

"So, I called the vet and I was able to sweet talk them into seeing Casper next week. His appointment is at five o'clock on Tuesday. That was the latest that they will give an appointment to a new dog."

"Okay, thanks, Will. I owe you."

"You don't owe me. I'll text you the address." Will tells him before he hangs up.

"How are you going to explain leaving to Voight?" Hailey questions.

"Cross that bridge when it comes to it."

"Maybe you should tell him. It might make your life easier."

"Or he could make my life harder."

They arrive back at the district before Jay can say anything else. The two go in to go over the footage before Voight can get on Jay's case again.
