Kate sat in the bullpen still staring at the screen still when Ryan, Esposito and strangely Rick returned.

"Hey look who I found on the way back up." Rick stated.

Kate didn't turn around she kept her eyes glued on the screen, Rick moved behind her to look at her screen.

"What are you…" He trailed off seeing the face. "Is that?"

"Jerry Tyson." Kate said.

"Who you found Beckett?" Ryan asked as he and Esposito came and stood behind them both.

"Tyson." Rick said.

"Where was that?" Ryan asked.

"Kelly's apartment the day she died."

"Maybe we can track him, see where he headed. I'll try and get the street camera's video footage." Ryan said.

Esposito and Ryan made their way back over to their desks. Rick who was still standing behind Kate's chair grabbed it either side and pulled her away from the desk.

"CASTLE?" She shouted.

"What?" He looked confused.

"What the hell are you doing?"

"Erm, getting you away from your desk so you can have lunch?"

"I can eat it here you know."

"Yes I know but you need a break from staring at that screen."

"I don't need a break."

"Beckett you have been sat at that computer since god knows what time this morning. All I'm asking is that you take five minutes."

"But…"

"No. Nothing is going to happen in five minutes while you sit down and just eat something."

"I swear if you are one of those protective guys now that I'm pregnant I'm totally going to hit you."

"I wouldn't dare try to change you. I'd probably die before I could."

She looked at him. "Do I have to sit in the break room and eat?"

"Not if you don't want too. Anywhere but your desk, now move it."

"Fine." She stood up and moved towards the break room, sitting on the couch followed by Rick who had bought some subs.

"Well I didn't know what you were feeling like today so I got you there special."

He handed her one of the two subs he had gotten and a drink.

"Does Alexis know you're back?" She asked.

"Not yet no."

"Why not?"

He checked his watch. "Because she will be in class and she doesn't usually check her phone until after school.

She nodded and then took a small sip of her drink.

They sat in silence mostly to eat, Rick kept glancing at Kate every few seconds. He stood when he finished and put his rubbish in the bin followed by Kate after a few seconds.

"There five minutes. Better?"

"Not yet."

"Now what?"

He walked to stand in front of her and placed his hand on her waist.

"I've just missed you." He brushed his lips against hers and then stared at her. "You're definitely coming with me when I go away again."

"What makes you think I'll come with you?"

"Because you missed me too."

"Don't get ahead of yourself."

"I don't need too. I have my information." He smirked slightly.

"I wouldn't believe everything you hear."

"I don't it's just you wouldn't normally allow me to be doing this in the workplace." He stated gesturing to them both.

She shook her head and smiled a little at him.

"That's better, now let's go out there and do what we do best."

They had both left on time that night, well Rick had to force Kate out but they had still left together.

"I mean it we're going." Rick said forcefully.

"And I already told you I don't want to go yet."

"What else is there to be done but wait for his next victim to show up?"

Kate stared at him. "I don't know Castle but I need to do something."

"And you can do, go home."

"You just don't understand." She stared at him.

"I can't believe you think that." He said stunned.

"Well it's true, soon I'm going to be running out of time to find him and someone else will have died by then."

"Don't you think I don't know that? Remember how he let me live, you don't think I'm feeling guilty over this? But right now I have to keep it together for you, I need to know you're okay."

She looked at him and took a breath. "I just don't know where to start to find him. It's frustrating."

"We'll find him but for now we're going to go home and spend an evening with Alexis." He stepped towards her. "Just don't get too carried away, stress isn't good for you right now."

"I know that when you keep reminding me every five minutes."

"Oh please it's not every five minutes."

"Okay maybe not but you keep reminding me."

"Just making sure you don't forget now get your jacket we're heading out."

The best thing about being Jerry Tyson was that he could make himself appear invisible if he didn't want anyone to see him. Right now that was exactly what he was doing, he was sitting in a low lit bar with a drink. For the last few nights he had been watching her and learning everything he could in the short amount of time .

Her name was Rebecca Smith, she was single lived in apartment block across the street. From what he had gathered she was 27, she was also going to be his next victim. She had been coming in for the last few nights he had and so tomorrow when she came in he was going to make his move. He had decided that he couldn't wait for Kate to come to him and she needed some encouragement.

So finishing the last of his drink he swiftly exited the bar and made his way back across town to the abandoned building. He opened his door walked to the back room and picked up a photo he had taken recently he smirked at her face. He stared directly at Kate Beckett.

"Don't worry you'll be mine soon enough."
