Catherine went back into work, she told Gil that Mark was with Kerri and Elizabeth and she felt the need to get back to work. It has been a slow night so far. Catherine sips her coffee in the break room. Sara walks in and says, "What a slow night."

Catherine says, "Tell me about it. I'm regretting telling Grissom that Mark was fine and was with Kerri and Elizabeth. At least if I wasn't here I could be doing something entertaining."

Sara nods and says, "Speaking of entertainment I can't wait to hear Mark's band tomorrow. Of us that are working Gris said he'd let us hang out there until there was a call."

Catherine says, "That's nice of him." Catherine cell goes off. It's a text from Mark.

Mark: Catherine meet me in the parking lot.

Sara asks, "Anything exciting?"

Catherine stands up and says, "Maybe it's Mark. He wants me to meet him in the parking lot."

Catherine walks outside and sees Mark's Jeep and walks up to it. Catherine says, "Hey good lookin' what are you doing here?" She leans in the Jeep to give Mark a kiss.

Mark smiles and says, "Would you believe I missed you?"

Catherine says, "Well I am pretty miss-able. Did you just leave practice? I figured you'd be out with the band bonding or something."

Mark just smiles.

Catherine asks, "What's going on? Did something happen at practice?"

Mark says, "Just disappointing most everyone there is still stuck in the past. A past I tried very hard to get away from."

Catherine says, "I'm coming around let me in." Mark unlocks the passenger door and Catherine climbs in. She asks, "Did something happen between you and Steph?"

Mark shakes his head and says, "Believe it or not she was not the problem it was Bobby."

After about a minute of silence Catherine says, "Are you going to tell me what happened or do I have to drag you into interrogation and beat it out of you?"

Mark laughs and replies, "He's probably just looking out for me and wanting things to be how they were back in the day; but it was almost like a sell job of why I'm not all over Steph."

Catherine asks, "So she gave you no vibe of wanting to get back together, Bobby just started this sell job all on his own?"

Mark shrugs and says, "That's what it seemed like. Steph and I talked about you and she asked if she was forgiven. Other than that our conversations were limited to songs. It was after practice and Bobby was telling me Steph and I have a history and she was broken up when I left the band. He also said that he thinks she was broken up because Steph is in love with me she just doesn't want to admit her feelings."

Catherine looks over at Mark and says, "What did you say?"

Mark turns to Catherine and blushes.

Catherine raises her eyebrows and teasingly says, "What you said to him was so good it made you blush? Come on I want to know what it was."

Mark smiles and says, "I told him that history was the problem with Steph there was too much of it. I didn't care whether she loved or still loves me. I said that I don't care that we've only know each other a week that I want to make a history with you and that counts for something."

Mark is interrupted by Catherine kissing him, they are interrupted by Brass saying, "Hey kids go the desert if you want to make out don't do it in the parking lot."

Mark and Catherine separate and slightly blush. Brass seeing who they are says, "Oh my bad please continue." Brass winks at them as he walks into the lab.

Mark and Catherine laugh. Mark says, "Something tells me we aren't going to live that down."

Catherine says, "You are probably right about that."

Mark says, "I should probably let you get back to work. It wasn't the day I thought it was going to be and I just needed a dose of you."

Catherine says, "We aren't that busy and if you keep saying things like that you're really going to like your reward."

Mark doesn't say anything he just smiles and takes Catherine's hand in his and she lays her head on his shoulder.

Mark finally says, "I like this, me and you talking about stuff that bothered one of us and the other making it better. In any other relationship I'm sure there would have been a fight about if I really did like my ex and what would happen."

Catherine says, "I think we've both been through that enough it's our time to put all the petty relationship stuff aside and have a loving honest relationship."

Mark suddenly hears Kerri's words in his head, "Have you informed her of this?"

Catherine takes her head off Mark's shoulder and says, "You go home and enjoy your time with Kerri and Elizabeth. I'll call you later." Catherine kisses Mark and exits the Jeep.

Mark watches Catherine walk in the building and drives off.

At Mark's Apartment …

Mark opens the apartment door with Chipotle in hand. He sits it on the kitchen counter. He notices Kerri sitting on the couch watching the season finale of Dawson's Creek and crying. Mark sits down on the couch beside her.

Kerri asks, "When did you get in?"

Mark replies, "Just now. I brought Chipotle home for everyone. Where's Elizabeth?"

Kerri says, "She got a call from her friend on the force, Tyler, and he told her she can actually take her detective test online. She's been holed up in our room for a while. So I broke into your Dawson's Creek collection."

Mark gets up to get his Chipotle.

Kerri asks, "So who did you have to go see?"

Mark smiles and replies, "I went to the lab and talked to Catherine."

Kerri smiles and asks, "Oh yeah what did you talk about?"

Mark rolls his eyes and replies, "I already know what you're getting at and no I didn't tell her."

Kerri shakes her head and says, "You are no fun."

Mark takes a bite of his burrito bowl and says, "Yeah that's me Mr. No Fun."

After a few moments of silence Mark starts laughing.

Kerri looks at him and says, "What?"

Mark says, "I was just thinking about the time you almost ran me over."

Kerri laughs and yells, "My car beeps for everyone but you!"

Mark laughs, "Last time I try to clean snow off your back window so you can safely drive!"

Kerri asks, "So what did you and Catherine really talk about?"

Mark replies, "I just told her I was disappointed that it seems like the band is living in the past and they want everything to be like it once was. I told her about Bobby's sell job trying to get me back with Steph. Then she asked if Steph appeared interested or if it was just Bobby. I told her it seemed like just Bobby."

Kerri interrupts, "Wait she didn't give you any shit about what may potentially be going on with you and Steph?"

Mark says, "No and I told her it was nice not arguing about an ex with a girlfriend for once. And she said we've both been through enough of that and it's our time and we're not letting petty things get in the way."

Kerri asks, "And you didn't confess your love for her after she said that? You're an idiot!"

Mark laughs and replies, "Ironically after she said that I heard your words from our earlier conversation in my head, 'have you informed her of this?' But she got out of the Jeep and told me to go back to you guys."

Kerri shakes her head and says, "That was a lost moment you know that right?"

Mark says, "True, but I am the king of those. You know I haven't told anyone how I feel about them in quite some time."

Kerri puts her hand on Mark's and says, "I know but sometimes you have to let someone in, I think Catherine could be good for you … really good for you in fact."

The guest bedroom door opens and Mark and Kerri look toward it; out comes Elizabeth looking completely drained and her hair everywhere.

Mark asks, "Hey are you ok?"

Elizabeth responds, "Ask me in a few weeks when they post the detective exam results."

Kerri hugs Elizabeth and says, "Honey, Mark brought you some Chipotle."

Elizabeth reaches for her burrito bowl and says, "Thanks this helps some. But I tell you as soon as I'm done eating this, I'm sleeping for an extremely long time."

Mark says, "Well I'm going to retire to my room as well, I need to go over a few songs before I go to sleep." Mark grabs his guitars walks into his room and shuts the door.

Elizabeth looks at Kerri and asks, "How did his practice go? I figured he'd be buzzing all about it."

Kerri says, "I guess things are fine with Steph, but Bobby rattled him a bit. Bobby gave him this speech about how broken up Steph was when he left the band and that he thinks she was that broken up because she really loves him but won't admit to it. Then Mark said that it doesn't matter that he wants to make a history with Catherine. Then he called me frustrated about it and basically admitted to me that he's in love with Catherine. He went to see Catherine before he came home and told her how frustrated he was with Bobby. And she didn't argue with him about it and told him that they'd both been through enough and this was their time and they didn't need to fight over petty things. Then I called him an idiot for not confessing his love for her after she told him that."

Elizabeth laughs and says, "Boo you have to give him time. Mark hasn't told anybody how he's felt about them in a long time, this won't come easy."

Kerri nods and says, "I know I just want to return the favor. If he hadn't pushed me I probably wouldn't have been with you as long as I have, I just want him to be happy."

Elizabeth kisses Kerri and says, "He will be babe you just have to let him do it on his terms."
