After a rough day working on a case that involves children, Jay Halstead stares at the blood dripping down his arm into his bathroom sink. The numb feeling leaving as he watches the blood leave his body. Watching as the water changes from red to pink, Jay is trapped in his tortured mind.

Jay is brought to when couldn't save his fellow soldiers after the Humvee accident.

"Three more weeks and we're back stateside," Rick Hillman states.

"Yeah, can't wait to get back to my girl," Aaron Carr states.

"You're whipped, man," a third voice calls.

Before anyone can reply the Humvee hits something just before flying through the air. Jay feels himself being thrown before blacking out.

When Jay wakes up, Mouse is above him talking, but he can't hear him. Realizing what happened, Jay attempts to sit up to look for his unit.

"Jay, they're gone," Mouse tells him.

"No, they can't be," Jay denies trying to get up to search, ignoring his own injuries.

The scene changes to inside a hospital room three months later, watching his mother die.

"Mom? Please don't leave me," Jay begs sitting in the uncomfortable chair at the head of the bed, holding her hand.

Weak as she is, Maeve Halstead takes her free hand and cups his face, "My sweet boy, I will always be with you."

"I still need you," Jay cries.

"There is so much that I will miss so much in your life and I'm sorry, but I know you will handle it like the kind, caring man I know I raised you to be. I am so proud of you."

"But Dad-"

"Don't you listen to your father- I want you to follow your dreams."

"Why aren't they here?"

"Don't be mad at your father and brother."

"But-"

"No 'buts'. It isn't you to be and stay mad at people, family."

"Mom, what am I going to do without you?"

"You are going to be okay. Baby, you were my miracle, my survivor. I love you so much, my Jaybird."

"I love you too Mom."

As the alarm goes off that Maeve Halstead flatlines, the scene changes again- this time to the war at home. Multiple images of different children he couldn't help, dead from gang violence, trafficking, and monsters in the street.

Jay snaps out of his thoughts and looks down at his arm. The water is now clear, the bleeding has stopped, leaving a fresh new cut to add to his collection. Jay stares at the cuts on his arm, each one for every time he couldn't save someone and for the times he's hurt people.

With the numb feeling still in his chest, Jay sends a text to Hailey before opening the cabinet.

"Hey, Hailey where are you going?" Adam asks Hailey is she is leaving his apartment.

"I'm going to check on Jay," she answers.

"What? We had the whole night planned," Adam complains.

"I got this weird text from him and now he's not answering- something doesn't feel right," Hailey tells Adam thinking about the text she got minutes before.

"Do you want me to go with you?" Adam asks.

"No, I'll call Will on my way."

"Will's not a cop."

"Will's his brother," Hailey answers. "You know Jay, he's not exactly an open person." Hailey leaves before Adam can respond.

"Have you heard from Jay?" Hailey asks Will when she is able to reach him halfway to Jay's place.

"No. Why? Is everything okay?" Will asks worriedly.

"Just the case. It's a rough one for him and he's blocking me out," Hailey tells him, omitting the text she got when she heard a commotion in the background on Will's end.

"Okay, I need to go, but I'll check in with Jay after my shift," Will tells her before hanging up.

Hailey throws her phone to the passenger seat after unable to reach Jay again.

After what feels like forever, Hailey makes it to Jay's apartment complex. Throwing her car into park, Hailey jumps out and runs up the stairs to Jay's apartment.

Hailey bangs on his door, hoping that he answers, "Jay open up!" When no one answers Hailey uses the key that Jay gave her for emergencies and drawls her gun.

Looking around, Hailey doesn't find anything out of place. Clearing each room, with still no sign of her partner, Hailey's chest grows tighter.

Opening the door to clear the bathroom, she finds Jay passed out on the floor. Putting her gun away, she reaches down to check for injuries. Finding none, she does a sternum rub trying to rouse him. When that doesn't work she feels for a pulse in his neck finding a weak one.

When Hailey finally looks up, she sees the empty pill bottles. The cop in her takes over and calls for an ambulance.

After what feels like forever, the faces of the two familiar paramedics of Firehouse 51 show up. While hooking Jay up to an IV and oxygen mask, they gather the little information that Hailey has on what happened. They quickly load Jay into the ambulance, calling ahead to Med.

Arriving at Med, Will is shocked to see his brother being wheeled in with Hailey following the gurney as close as she can before she is stopped as Jay is taken into a treatment room.

Ethan rushes in to take care of Jay while Connor has to use all of his strength to stop Will from charging into the room. Hearing the words, 'overdose' and 'possible suicide attempt' stun Will to his core. Asking himself how he hasn't noticed, or how could that be his brother.

"What happened?" he asks Hailey, hoping for an answer.

"I don't know," Hailey tells him. "I got a weird text from him and then he wasn't answering me back so I went to his place. Nothing was out of the ordinary… until I reached his bathroom. He was laying on the floor unconscious with a bunch of empty pill bottles. I called for an ambulance and they brought him here. Will you have to believe me: I had no idea Jay was in this bad a place. I mean I know he was taking the case hard, he always does when it involves kids, but I never thought he would do something like this. I wouldn't have left him alone if I did," Hailey continues, still shocked by finding her partner.

"I know. You're a good partner. Thank you for checking on him when you did," Will thanks while trying to absorb what she just told him.

Looking into the treatment room that has her partner, Hailey asks, "Is he going to be okay?"

"He's a fighter and a survivor, he has been his whole life," Will answers.

"But what if he doesn't want to anymore?" Hailey asks the question that neither wants to address.

They both remain silent, both scared and worried, both praying Jay will be okay and vouching to never let him out of their sight again.
