It had been three weeks since they decided to "cool off". Well, things were definitely cold between them. They hadn't had a real conversation since the locker room.

Erin was sitting at her desk and trying, with much difficulty, to not look across the room to her partner's desk. She missed him. She didn't want to cool things off between them, but Voight found out and it scared her. She gave up and looked over at her partner. He was struggling with his huge pile of paperwork, not realizing she was watching. Jay always put off his paperwork and would end up staying late to finish it.

"I can't believe I do this to myself." Jay groaned and rubbed his eyes.

"Me neither. I'm all done." Erin said with a smirk.

Erin got up and walked over to his desk and sat on the corner. Jay looked up at her and chuckled.

"You know, Erin, I'll never get anything done with you sitting there looking at me." He said smiling.

"That's why I'm leaving, Jay. I think I'll take a long hot bath and maybe catch the blackhawks game. Maybe I'll just sit on the couch in my underwear, if I even wear them at all"

"Don't do this Erin." Jay said, picturing that particular option and groaning softly.

"Do what?" Erin asked, innocently.

"You're teasing me." Jay said with a fake glare.

Erin laughed as she put her coat on and grabbed her keys. She kissed him and walked out, leaving him with his pile of paperwork, and Erin's suggestion in his head, at his desk in the empty bullpen.

That was weeks ago, and everything had changed. Voight re-partnered them, Erin and Dawson, Ruzek and Jay. They had been avoiding each other for weeks. Erin was distant and cold to Jay, and Jay was taking the whole thing in stride, even though he was a mess inside. Ruzek was meeting a CI and Jay was dealing with a personal matter. Erin and Antonio were in the bullpen. Voight came in with a grim look.

"Suit up. Shots fired in an apartment building on 89th ave." Voight said as he pulled Antonio and Olinsky aside. They all looked down and then moved to suit up.

"What's up? You aren't going to tell me Hank?" Erin said, curiously.

They all looked at her and she shrugged. They drove to the apartment and Erin gasped.

"That's Jay's car! Hank..." Erin said scared.

As soon as they entered the apartment all you could see was the blood. They they saw a trail that led to the bedroom. Erin opened the door to find Jay propped up against the wall and a man laying dead in the room by the bed. She gasped and chocked back a sob.

"Erin?" He asked, and he coughed, blood trickling down his lip.

Erin just stared at the him, as she lowered her gun and nodded at Antonio. He went to radio an ambo. She recovered quickly and hurried over to her partner, the man she- not now Erin...

"Jay? Are you okay? What happened?" She asked calmly.

"He came at me, shot me, I shot him..." He said nodding off.

"Jay! Stay awake remember?" Erin said softly.

Jay opened his eyes and smiled. He looked at Erin and his smile faded.

"I'm sorry, Erin. About all of-" He started.

"Don't you dare apologize Jay Halstead! I'm the one who's sorry. I never wanted us to cool off."

"God, me neither. Ruzek lets me drive. It's not all that it's cracked up to be." He smirked. She laughed.

"Er, I want you to know that I-"

"Hey, tell me when you're better okay?" Erin said hurriedly.

"I love you, Erin. I always have, and I just wanted you to know..." He said and then closed his eyes.

"Jay! I love you too! Please. Don't leave me." She said softly, knowing he couldn't hear her.

At the hospital, Jay was rushed into surgery and everyone gathered in the waiting room. Voight was pacing and Antonio and O were sitting by the window. Ruzek and Burgess, were standing by the desk, trying to get information. Erin was sitting in a chair with her head in her hands.

"Erin, sweetie? Want to get cleaned up?" She looked up to so Gabby, Antonio's sister, holding her hand out. She was married to Lieutenant Matt Casey, and was a firefighter over at firehouse 51, and they were all good friends.

Erin hadn't thought about what she looked like. She said no and Gabby sat down with her. She had never really thought Gabby liked her much. Gabby was sweet and funny and caring. Erin wasn't.

"Whenever Matt does something stupid and heroic, ending up in the hospital, I would wear his shirts or sweaters. It was like he was holding me, I could smell him, and I knew it would be okay."

"Thank you Gabby. For being so nice." Erin said, with a sad smile.

After a while she went to the cafeteria to grab coffee. She walked back to the waiting room and saw the doctor leaving.

"What did he say?" She asked, to nobody in particular.

"He's still in surgery." Voight said from the chair.

"Don't talk to me. This is YOUR fault Hank! I should've been there, to watch his back!" Erin screamed and slid back down into the chair and sobbed.

Nobody had ever seen Erin cry, not even when she got hurt in the line of duty. So seeing her in the chair sobbing, everyone wasn't sure what to do. Gabby went and sat next to her and held her.

"Hey. Erin? I'm sorry I wasn't there to-" Ruzek said, voice breaking.

"Adam. It's okay. I know he's your best friend." Erin said sniffling.

"I want to see him. I'm going to see when he gets out of surgery." Erin said, standing up.

"No. You need rest." Hank said sternly.

"I need him, Hank! And I don't give a damn about what YOU think I need." Erin snapped.

"I said it as your Sargent. Erin get some rest."

"You can't separate the two! You know why I'm doing this. You know how I feel about him."

"Yes. Because you and Halstead disobeyed me and you seem to be hell bent on keeping the pattern."

"You're wrong, Hank. It isn't about you."

"Erin, I'm done arguing. You put each other in danger when you started seeing each other. It's over between you two, and that's something you're going to have to accept."

"Damn it Hank, I love him!" Erin cried.

Everyone froze when Erin admitted she loved Jay. It was like the world stopped. She just started sobbing again and collapsed back in the chair. Gabby and Sylvie sat with her and comforted her.

Meanwhile at district 21, a young girl, about 15 walks up to the desk. Platt, looks down at the girl and smiles.

"Hi, what can I help you with?" She asked the girl.

"Um, I have two things, the first is about a Detective, his name is Jay Halstead?" The girl asked.

"He's in the hospital, he was involved in a shooting this morning. How do you know him?"

"He's my uncle. My name is Piper Marie Halstead. And I want to turn myself in." Piper said softly.

"Turn yourself in for what?" Platt asked, confused.

"Murder." Piper said quietly, looking into Platt's eyes to show she was being truthful.
