After everyone had finished their Chinese Catherine reminded Lindsey that she was leaving in about an hour for her weeklong trip to Disneyland with Jeremy and Aunt Nancy. Lindsey gets frustrated, "But mom I just really started to get into this Sims game."

Catherine says, "Linds you've been looking forward to this trip since Jeremy and Aunt Nancy asked you to go. I'm sure Mark will let you play again when you get back."

Lindsey looked at Mark, "Can I play when I get back?"

Mark thought how could he say no to the young blond, "Of course."

Catherine says, "Linds I've packed most of your things, but why don't you go check and see if you have everything you want."

"Ok Mom," said Lindsey as she went upstairs.

Here it was Mark and Catherine's first moment alone since they had sex last night. It was very quiet until Catherine quickly asked, "Mark would you like something else to drink?"

Mark looked at his now empty glass, "Sure."

Catherine takes his glass and enters the kitchen to fill it up. She returns few moments later with a full glass. She hands it to Mark.

"Thank you." Mark says taking the glass.

Catherine looks at Mark, "So how long are you going to be staying at the Bellagio? I imagine it won't take long for that to get expensive."

Mark puts his glass down on the coffee table in front of Catherine's couch, "Only a few more nights, they said my apartment should be ready on Wednesday."

"What made you decide to move to Vegas?" Catherine says taking a sip of iced tea.

Mark turns on the couch to face her, "I really just needed a change of pace. The lab I worked at in Ohio was very small and didn't have much funding; I felt I had done all I could ever do there. How small the lab was though did give me a chance to work in several areas and gain experience I wouldn't have gained in a larger lab. I credit that to being able to work in both computer forensics and the field now."

Catherine says, "Yeah I really like working in our lab but you really only get the chance to specialize in one area."

Mark asks, "What is your area of specialization?"

"Blood spatter analysis." Catherine says sitting her glass of tea on the coffee table and situating herself on the couch so she is facing Mark.

Mark nods in an impressed way, "Wow I can't wait to work in the field with you, that is an area I have always wanted more experience in."

Mark puts his hand on Catherine's and starts to rub it and gives her a smile.

Catherine returns the smile, "I'm sorry about all of the small talk. It will just be easier to talk once my sister picks up Linds."

Mark continues to smile, "It's ok I'm not going anywhere."

A few moments later Linds comes downstairs with her bags in hand and asks, "Are Aunt Nancy and Jeremy here yet?"

"No sweetie not yet but I expect they'll be here any time now."

A few minutes later there's a knock at the door and Catherine gets up to answer the door, "Hey Nance."

Nancy walks in seeing Mark on the couch, "Hello I'm Nancy, Catherine's sister."

Mark gets up and shakes Nancy's hand, "Hi I'm Mark, I work with Catherine."

Nancy smiles, "Nice to meet you." Nancy turns to Lindsey, "You ready Linds?"

"Yes," Lindsey responds. "Mom are you coming out to the car?"

Catherine says, "I'm right behind you Linds."

Lindsey turns around before walking out the door, "Bye Mark see you when I get back."

Mark waves, "Bye Linds."

Catherine turns to Mark and mouths I'll be right back.

Catherine helps Nance put Lindsey's bags in the back of the car and kisses Linds goodbye as she gets in the car.

Nance turns to Catherine and gives her a playful smack, "So please tell me you are more than co-workers with that cutie in there on the couch."

Catherine smiles, "Maybe I'll talk to you more about when you get back."

"You better!" Nancy says with a teasing tone as she gets in her car and leaves.

Catherine walks back in the house and looks at Mark, "So …"

"Yeah," is the response Catherine gets from Mark.

Catherine says, "Not to make this such a serious tone but, we need to figure out what we are going to do about this thing between us. Don't get me wrong I really like you, but now that we work together there is suddenly more on the line than there was before."

Mark looks at Catherine who is now sitting next to him on the couch, "What's the workplace policy on inter office dating?"

Catherine says, "It's frowned upon, but I don't know anyone that has really come out and said that they are dating either. I'm sure we'd have to go to Gil and possibly Ecklie and explain that we are dating. There is the chance that they would put us on different shifts. I don't know that we really want to rock the boat though, with you just starting work and us just starting out, it may just be best to wait and see if this turns into anything serious and then go to Gil and find out what the consequences are at that point. Not to mention that Linds is involved in any relationship I have, if something were to happen it not only affects me but her. I think maybe we should take it slow; even though we really sped things up last night, kind of see where this goes. What do you think?"

Mark looks at Catherine and takes her hand in his and says, "Miss Willows would you kindly allow me to take you on a proper date?"

Catherine looks at Mark and blushes slightly, "Sounds like a great idea to me."

Mark leans in and gives Catherine a long slow kiss.
