Catherine stood in front of a blood spatter pattern aimlessly starting into space. She is lost in thoughts of last night and how Mark is now working at the lab. Catherine is thinking this could get complicated and that she needs to speak with Mark after shift. But of course her thoughts immediately go from needing to speak to Mark about their relationship or fling or whatever to kissing him. Grissom walks by waking her from her daze and says, "I know you've almost worked a double today you can go home if you need to."

Catherine responds, "No I'm fine, just lost in some thoughts, sorry Gil."

"No problem, Cath, is it something you'd like to talk about? You know I'm always here for you."

Catherine quickly changes the subject, "I'm thinking the suspect was standing over the victim and giving some heavy blows with the trajectory of this spatter."

Gil quickly snaps a picture. "Yes, I agree. But what do you think could have left this large void here?"

Catherine looks at the wall inquisitively. "Gris I'm thinking something was here. Doesn't that void resemble a small end table to you?"

Gil looks around the room. "Could be, but where is this table now, and why did the suspect move it?"

Back at the lab …

Archie is going over all of the equipment available to Mark in the AV lab. Granted this is the nicest equipment that Mark has ever seen in comparison to the resources he had to his disposal in Ohio, but Mark's mind was focused on one thing and one thing only … Catherine.

"Then of course we have this giant 70" LCD TV to project onto from the computers. Don't tell Ecklie but Greg and I had an Xbox party in here recently." Archie notices that Mark is somewhere else. He waves his hands in front of Mark's face you get his attention. "Hey, Mark, buddy, you with me?"

"Oh yeah sorry. What were you saying?"

Archie laughs, "Come on I was totally nerding out by telling you about the Xbox party I had in here with Greg and got nothing out of you. Are you sure you're a nerd?"

Mark responds, "You won't ask that question again when I lead kills in Call of Duty Team Deathmatch."

Archie raises his hands as if to surrender, "Oh man it's cool, I was just playing."

Mark laughs as him and Archie start working some evidence together.

A few hours later after combing through some security footage from a gas station robbery Sara walks in with a young blond haired girl and says, "Hey Arch, hey Mark. You guys into anything interesting?"

Mark looks at Sara, "Other than our eyes about ready to fall out from the gas station security footage? No."

Archie laughs. "What's up Sara?"

Sara says, "I just got paged by Henry to go over some evidence and I was wondering if you guys would care to entertain Lindsey for a while?"

Archie says, "Sure no problem."

Sara walks Lindsey toward Mark. "Mark I would like for you to meet Lindsey Willows, Catherine's daughter." Lindsey shakes Mark's hand. Catherine has a daughter Mark thinks to himself. Well, if he is ever going to have a chance with Catherine he better win over her daughter, this he knows.

"Nice to meet you Lindsey. I'll tell you what I have The Sims 3 on my laptop. Would you like to play?" Mark says getting his laptop out.

Lindsey's eyes go wide. "Yes, I've been begging my mom to get me that game for a while!"

Setting up the game and a chair for Lindsey Mark says, "Well I'll tell you what. You can borrow mine anytime you want."

"Really?" Lindsey looks up at Mark.

"Absolutely kiddo!" This brought a huge smile to Lindsey's face.

Sara left to go check on that evidence as Mark and Lindsey were chatting about various things. Mark learned that Lindsey was 12, she liked science, and would really like to get dog.

In the locker room …

Catherine is changing and getting ready to leave. Sara walks in, "Hey Cath, your mom dropped off Lindsey a while ago. I had to go check on some evidence but I left her in the AV lab with Mark and Archie."

Catherine shakes her head, "Thanks Sar. I really wish my mother would call me when she needs to leave Linds here. I just hope she hasn't taken over the AV lab too much, I know that gas station security footage still needed processed."

Opening her locker Sara says, "Mark and Archie had just finished when I brought Linds in they both looked like that needed a break." Sara chuckles, "Oh Linds may not be asking you for The Sims 3 again anytime soon, Mark has it on his laptop and set it up for her to play, also telling her she could borrow it anytime she wants."

Catherine smiles thinking of Mark bonding with Lindsey. Also wondering why this thought made her so happy considering she's barely known Mark a day. "Oh yeah, I like this Mark guy already he may have just saved me $50."

Sara laughs, "Yeah tell me about it. Gaming has gotten to be very expensive."

Catherine turns to leave the locker room to pick up Linds in the AV lab. "See you later." She calls back to Sara.

Catherine walks into the AV lab, "Hey guys Sara told me she dropped off Linds, I hope she hasn't been too much trouble."

Archie laughs, "Are you kidding? I think her and Mark are BFF's."

Catherine and Mark look at each other and share another moment. They are interrupted by Linds, "Hey mom, can Mark come get something to eat with us?"

Catherine looks at Mark, "Sure if you really want to eat with two Willows women, it can be an adventure trust me."

Mark smiles and rubs Lindsey's head, "Are you kidding me? Nothing sounds better than that right now."

Catherine smiles and turns to Lindsey, "Where would you like to go?"

Lindsey thinks on this and realizes that she would like to continue playing Sims on Mark's laptop. "Maybe we can go home and order Chinese. I can continue to play Sims on Mark's laptop and you two can do boring grown up talk or something."

Catherine says, "Oh really, well you are going to have to ask Mark that question since it is his game."

Lindsey turns to Mark, "Please can I continue to play on your laptop at my house?"

Mark smiles and says, "You got it kiddo."

Catherine looks at Mark, "Want to just follow us to my place?"

"Sounds good," Mark says as he follows Catherine out to the parking lot.

It was Sunday around noon when they stepped out of the crime lab the sun beating down. "Wow, I really have to get used to these hours." Mark says putting on his sunglasses.

Catherine says, "Oh yeah you didn't work nights where you were? It does take some getting used to in the beginning."
