*Hides face behind hands* I know. I realize it's been 9 months since I updated, but I'd lost my Linstead touch for a bit and got wrapped up in my AU story. I can say I'm back now and I've written some linstead one shots if you want to read them. I have to say I promise I will get your idea out, Bhea4758, and you'll see it a little bit here, but I'm gonna try and make it its own chapter. Thanks to kkmallow3 for help sorting out the ideas for this.

As always I own nothing but my own ideas.

Emotional Chapter 10

It'd taken Erin about six weeks to make a full complete recovery. The first two weeks they'd spent working through emotions and blame, talking it out until Jay believed he wasn't at fault. Then he went back to work and she was still doing PT. On the fourth week she was cleared for desk duty and two weeks later she was back to full duty.

It felt great being back, and Jay was back in a better place. Things were going good with them.

They'd been working a case all week and hadn't really had much time to spend just them. She could tell by Friday we was getting worn down, and she would be glad when they wrapped the case up.

Friday afternoon they were back at the district so Voight could interrogate their suspect, and close the case. The team was chilling in the bullpen just waiting when Platt walked up. "Halstead, visitor," she said.

Jay and Erin exchanged a look because he wasn't expecting anyone. "I'll send him up?" Platt said before going back down. Erin and Jay assumed it must be Will making a surprise stop by.

Adam, Kevin and Antonio went to the break room to get drinks while Erin stayed with Jay.

The man that topped the stairs definitely wasn't Will so Erin was curious now. She glanced over at Jay and he'd gone rigid sitting on the edge of his desk. His face had paled considerably as well. She was instantly worried.

"Jay?" the man said holding his hand out.

Jay refused to take it which was unusual and he backed away just a little after standing.

"Detective Lindsay," Erin said shaking his hand instead as she kept glancing at her partner. She noticed some facial features similar to Will but she wasn't sure. She could tell the guys were watching from the break room as well.

"Jay?! Aren't you going to say anything?" the man questioned with a smirk.

Erin stepped closer to Jay as she watched him. It was almost like he couldn't breathe and he was seriously whiter than he should be. Before she could ask the man who he was or what he wanted Jay hit the floor. He'd passed out cold.

The guys came running from the break room as Erin tried to wake him. She sent Antonio to get Hank not caring that she'd be interrupting his interrogation as she sent Kevin a pleading look to get rid of this man. He nodded and got up grabbing the man by the arm and escorting him back down the stairs.

Adam radioed in that they needed an ambulance stat for an officer down and he helped Erin try to get Jay awake. Hank, Al and Antonio returned quickly and the four guys managed to lift Jay and get him down to the roll up to wait on the ambulance. Kevin joined them after getting rid of the man.

"He kept screaming I couldn't keep him from his son," Kevin said to Erin.

It suddenly all made sense and she sent Hank a look. They loaded Jay in the ambulance and Erin jumped in too. Hank told the others to get busy digging on Halstead's father; he wanted an update when he called. He jumped in his SUV and followed after the ambulance to Med.

Jay came too in the ambulance after receiving a little oxygen. Erin was so glad to see him awake and softly rubbed his cheek. "It's gonna be ok," she whispered.

"Where is he?" Jay whispered trying to move the oxygen mask.

"Gone. Kev made him leave," she said putting it back on him. Before anything more could be said they pulled up at Med and unloaded him.

She spotted Will first thing and yelled for him as Ethan took over assessment.

"What happened?" Will asked rushing over despite knowing he couldn't work on his brother.

"It's been a long week with a case. I could tell this morning he was wearing down. We were waiting as Hank did the interrogation and some man came to see him. Jay wouldn't speak or shake his hand. He turned so white and before I knew it he passed out. I had Kevin escort the guy out and he kept screaming at him that he couldn't keep him from his son. This can't be your dad right?! He's not around right?" she asked Will.

Will watched Jay carefully as Erin relayed what happened. "It is," he said seeing their dad enter Med. "Erin stay here and no matter what do not let anyone in this room but Ethan or a nurse," Will said rushing out and slamming the sliding door closed.

Ethan had heard the exchange and decided to stay. Jay was stable but from Will's reaction that could change soon.

Voight was right behind their dad and walked in just as Will intercepted him. "What are you doing here?" he growled.

"William, my boy. I didn't expect to see you here."

"Don't touch me," Will said moving his hands. "What are you doing here?"

"Now son, that's not how you treat your old man. Come here give me a hug," he said holding his arms out.

"I said don't touch me!" Will growled as Hank walked closer.

"William stop this. You know better," his father said grabbing his arm.

Will twisted out of his grip as Hank stepped over. "I believe the doctor requested you not touch him," Hank said flashing his badge.

"Leave us alone. This is a family matter."

"Sargent Hank Voight," Hank said sticking his hand out.

"Dr. William Clayton Halstead."

"I see," Hank said.

"What did you do to him?" Will asked cutting the bullshit. He already knew from Erin, but he wanted to see what he'd say.

"How dare you William! I did nothing. Just tried to have a conversation with my son and he passed out. Now I want to see him. He must be sick to pass out on the spot like that."

"I don't go by William," he growled his red headed temper getting the best of him. "And under zero circumstances will you see my brother."

"He's my son. I can see him if I want," William said trying to push Will out of the way.

"You will NOT see him," Will growled shoving him back. "He's never been your son and he's not starting now. I'm gonna say this once and you better listen and listen good. Leave us the hell alone like you have for the last three years and don't come back!"

"How dare you?!" William cried.

"Leave!" Will growled shoving him at Voight knowing he could count on Hank to get rid of him.

He could hear William's protest all though out as Hank escorted him away. He let out a sigh and ran a hand through his hair when he felt a hand on his back.

"You ok?" Natalie asked softly.

"Yea I'm fine. I've gotta check on Jay," he said kissing her forehead.

Natalie nodded and followed after him.

"Will?" Erin asked as soon as he walked through the door.

"He won't be back here," Will said reassuringly automatically checking Jay's vitals. They were up from when he'd come in and that made Will feel better.

He ruffled Jay's hair carefully. "Rest brother, he can't hurt you anymore," Will said dimming the lights. They were gonna let a full bag of fluids run and keep him on oxygen before sending him home.

Will's shift ended as the discharged Jay. He told them to come over for dinner, Nat having already gone home and cooked. Jay and Erin agreed and followed Will to his apartment.

They ate and played with Owen some before Natalie took him to get ready for bed.

"You ok?" Will asked Jay.

He was curled on the couch with Erin and he gave Will a nod. "Yea. I just was surprised today."

"Yea I know. Maybe he'll listen though and we won't see him again."

"I hope so," Jay said as Erin ran soothing fingers through his hair. They stayed and chatted a while longer before going home. It'd been a long week and a long day, and Jay just wanted to curl up in bed with Erin blocking it all out.

He prayed this was the only time William decided to just pop up. While he knew he could defend himself now, and honestly he could kill the old man with a few right moves, his body and mind still resulted to that fear. It was that fear he never wanted Erin to see again if at all possible.

Ok so I know it was so shorter than normal and not all that emotional, but it was setting up their father just popping in and the effects it's gonna have. Hope you're still with me and will leave me your thoughts. More coming soon I hope. :)
