"He looked messed up, like he had had a bad day and said he had things to take care of. He wanted to know where he could get a gun. I refused to help and sent him away."

"Did he say what he needed a gun for?"

"I don't ask, I don't need to know. The less you know in this business, the better"

That was the last time John had seen Geoff and time was up. John asked them to leave.

Trident Hotel – Later that night

The group of detectives gathered at the meeting room Montgomery requested to share information. Ryan and Esposito ran through their findings.

"Every Wednesday, the hotel hosts a small mingling party at the dance hall on the ground floor for the staff. Most of the staff attend, but guess who didn't show?"

"Geoff Grines!" yelled Castle with his hand raised high like a child answering questions in class.

"Genius Castle, he was dead. He attends every week, but staff recalled seeing him on that Wednesday morning and he said he had to attend a business meeting in New York."

"Wait, let's put a time line on this" Beckett said as she grabbed a paper and pen, "We found Grines on Friday morning. The time of death estimates to be about night on Wednesday. Staff party was on Wednesday night which means he must've left Vegas on Wednesday morning after seeing the staff, his passport confirms. The killer knew about his plans and followed him to New York", she paced forward, "we need the airports checked."

"Ok," Montgomery cut in, "it's midnight and we all have to get up fresh tomorrow for the case. Let's all get some rest."

When Lanie, Castle and Beckett arrived on their floor, an awkward silence ensued. Castle knew that all hopes of anything flirtatious happening was not likely with Lanie present, thus he retrieved to his room first and closed the door. Lanie's eyes followed him, and then returned to Beckett as she proceeded to leave.

"Now are you going to tell me girlfriend, or am I gonna have to force it out of you?"

"Nothing is happening Lanie. You'll be the first to know if it is." And with that, she retrieved to her room.

Beckett had changed into her white singlet and shorts and headed for bed. She stopped on her way in hesitation and turned around to look at the adjoining door that connected her room to Castle's. She twisted her face into one who just ate a sour lemon, walked over and unlocked the adjoining door. What was she doing? She didn't want him to think she was easy, she thought to her self. She walked over to the bed and switched the TV on. A quarter of an hour had past and she had given up all hopes of any mischievous happening that night. Just as she completed her thought, the handle on door turned. She reached for her gun in the bedside table drawer and pointed it at the door.

"Kate, are you awake?" Castle whispered as he peered through the gap of the door with two take away coffees and boxes of pasta.

"Castle you scared the crap out of me, why didn't you use the front door, and where did all that food come from?"

"I got these downstairs at the café and I heard you unlock our adjoining door" he said with a huge grin which made her blush, "and then I thought, I am extremely peckish." Beckett couldn't help but laugh. They went over to the table in her room and dug in to their late night meals. Castle couldn't help staring as he ate his pasta dish.

"Stop staring, Rick." Beckett couldn't stand the attention. He was gawking at her whilst she ate.

"Can't help it, you're too mesmerizing" he beamed and then turned his attention to the TV.

When they finished, Beckett took the boxes to the sink to wash. She felt hands caressing up her back to play with her hair. Castle twisted her hair around his fingers to see how curly it would stay after he had let go. His breath travelled heavily down her neck making the tiny hairs stand on end.

"Rick, you're such a child, at least help me with the dishes"

"But this is more fun" he laughed. She turned around to face him.

"Why do you look worried?"

"We agreed on moving slow and I don't want to overstep boundaries" he replied honestly. She looked at him tensely with her brows furrowed. She couldn't believe that he respected her enough to keep his word. Something inside of her screamed JUMP and she leaned forward and felt the skin of his neck on her face before she planted a kiss.

"You're confusing me on purpose aren't you?" Castle was shocked at her forwardness.

"No, I'm just speeding things up a little" she replied shyly.

He drew her close and placed his forehead on hers. In the midst of a lot of heavy breathing, Castle drew her mouth to his and kissed her deeply. She responded with a soft moan of satisfaction as her heart jumped up to her throat. He then put his hands around her waist and effortlessly carried her to the lounge and sat her on his lap. They plunged into each other, pulling and grabbing at one another's clothing. Castle was very careful not to overstep any boundaries, but Beckett pushed further and worked the second button of his shirt. Just as they fell on top of each other on the lounge, one of the adjoining doors opened. It was Lanie.

"Oh my god" Lanie gasped at the sight of Beckett on top of Castle, "you have a lot of explaining to do young lady."

Lanie startled them making Beckett jump.

"Lanie!" screamed Beckett as she pushed herself off of a confused and squashed Castle. Lanie however, was smirking devilishly.

"I knew you two were doing the slow tango" she said with a wide smile. Beckett and Castle sat, with lips pursed, still on the lounge like two teenagers who had been caught making out.

"How come you're not asleep, did we wake you?" Castle asked raising his head up finally to look at Lanie.

"No, I couldn't sleep, just thought I come by and visit my best girl. I didn't realise her hands were tied" she turned around to leave.

"You can stay Lanie, Rick should get some sleep anyway" Beckett said hinting for him to go back to his room.

"No, no, I think I'll sleep better now with that last image in my head" Lanie laughed to herself noticing the horrified looks on their faces, "I'm kidding! Let's all get some sleep."

After Lanie left, an awkward silence plagued the room. Castle took it as a sign to leave but was secretly praying for a sign from Beckett.

"Rick" Beckett called out, "you can sleep here tonight, but on one condition, that I get my good night's rest."

Castle pulled a fist in front of his face and mouthed out a 'yes'. He then walked over to where Beckett was lying and tucked himself in to the other side of the bed. It felt very weird for both of them to have someone snuggled in on their side, sleeping next to another being. But something comforting and warm was felt inside of them. A feeling of security and content overcame them.

"Until tomorrow, Kate" Castle said as he adjusted his head to his pillow. Beckett leaned over and kissed him gently on the cheek.

"Night, Rick" Castle pulled her in to him and held her as they fell asleep.
