A/N: So, let me apologize. The last 2 months my life, turned upside down. I've got things pretty much in order, and I came back to this fic to see that it was almost finished. I hate making you all wait this long and then ending it, but the story has run it's course. This one, and at least one more, but I would say no more than three chapters total. It's time to do some colliding.

A/N 2: He's probably gonna hate this, but oh well...Mojo...thank you. Publicly, thank you! He's been betaing for me for a while now, but this chapter we stopped and had a long discussion that made me revise it three times. I just want to say that it takes a partnership to make betaing work. Sometimes you gotta stop and listen to people's concerns and he brought some things up to me I truly did not consider. So again, thank you.

Disclaimer: I don't own Chuck

Chuck stood there, pouting.

"I said no," Sarah told him, taking a bottle of water, and looking at him. "Chuck!"

"I'm not saying anything," he replied, the pout remaining.

"God," she muttered. "Fine, ONE!"

"What about my construction joke… wait, that won't do, I'm still working on it."

"Oh Jesus," she muttered.

"Morgan said to me, 'What rhymes with orange?' And I told him, 'No, it doesn't.'"

"I said just one!"

"It's like having Pringles, you just can't stop the pop."

"Chuck, I will kill you in your sleep," Sarah said, her eyes blazing.

"No, you won't," he replied, taking a step towards her.

"Have they been like this all day?" Emma asked Grissom softly.

"All week," Grissom replied.

"Good grief, maybe they need one of their own," Emma said, watching them move inches away. "They wouldn't… they do know we're here, right?"

"I'm not sure," Grissom admitted. "Whatever happened between them, it seems like they've gone to that next level."

"I'm not entirely sure, but I'm happy for them." She looked over at Grissom, leaned over, and kissed his cheek. "Thank you."

He blushed and gave a head nod, too embarrassed to say anything. "Bartowski, if you can quit flirting with your girl, I need your help," Grissom yelled.

"I need to go," Emma said, patting Grissom's arm.

"See ya, Emma," he said, watching her go.

"You ever think about asking-" Chuck began.

"Stuff it," Grissom said gruffly, but with a telling grin on his face. Chuck followed him to the office.

Sarah scooped up her little girl as the baby crawled on one of the mats. She was babbling nonsensically, when Sarah felt her spy sense go off. She looked up and saw a man had entered the gym. She had never met him before, but there was something about him.

"Hello," he said, nodding toward her. He seemed… odd. She didn't feel he was dangerous, or a threat, but he seemed odd. His movements were somewhat erratic as he walked towards her. "I've been thinking about-about getting in better shape."

"Then you've come to the right place," Sarah said. Molly reached toward the man. "Sorry, she's not usually so grabby at strangers."

"It's-It's okay," he replied. "Is she yours and that young man's I saw?" He turned quickly and pointed at the big window that was by the street. "I see you three sometimes walking by. And- a- and an older gentleman."

"No, I've adopted her," Sarah replied, surprised at herself for being so honest with a stranger. "He and I are dating, we're not-"

"Dada," Molly blurted out. The man's eyebrows raised. She clapped her hands at the man. "Dada," she said, reaching toward him.

"Molly, that's not Chuck," Sarah said, laughing. She looked at the older man. "Sorry, sir…I don't think I caught your name."

"Stephen," he said.

"I'm Sarah," she replied. "As you can see, we're family focused."

"I can," he said. "Could you give me a tour?"

"I would be glad to," Sarah said, beaming. She was struggling with Molly, who kept reaching for Stephen. "Molly," she said, exasperation in her voice.

"Do you mind?" Stephen asked. Sarah looked at him and then to Molly, shrugged, and handed Molly to Stephen. "Hello, little one," he said softly.

"Dada," she cooed, and laid her head on his shoulder.

"Hey, Sarah," Chuck called out, coming around the corner. She saw Chuck's face as the smile fell from it. Chuck's mouth dropped a little.

"Charles," Stephen said. "How are you?"

"Fine… Dad… and you?" Sarah stood there with shock on her face.

"Dada," Molly said, her head against Stephen's shoulder.

}o{

"What are you doing here, Dad?" Chuck asked after he had sat down and gathered his bearing. "I don't see you for years, and then you just show up."

"This may have been a mistake," Stephen said, trying to hand Molly back to Sarah, but Molly refused to go.

"Dad, stop," Chuck said softly. "There's no sense upsetting Molly. Why are you here?"

"Because I might know a way to get your mother home," he began.

"Mom's alive?!"

"Perhaps I should have started with that."

}o{

"I really hate him some days," Chuck said a little later. He and Sarah were by themselves, while Stephen talked to Grissom. The rest of the crew were on their way to the gym after Stephen told them Mary was still deep undercover on a CIA op.

"Sweetie, I get that your mad at your dad," she began.

"No, no," Chuck said, shaking his head. "You don't get it. I really hate Morgan, and that stupid book." She gave him a look. "The family collision is the collision that can hurt most of all. Mothers and daughters, fathers and sons, they can hurt each other deeply. The mind is amazing at hiding these reminders from us, until one day, we collide with them, and then it all comes back. It all bubbles to the surface, and that which we have pushed down, we now have to deal with."

Sarah took Chuck's hand, and Molly reached for Chuck. Chuck took her, and she snuggled against him.

"Dada sad," Molly cooed.

"He is, pumpkin," Sarah said, giving her girl a sweet smile.

"Hey, I'm never leaving you, you know that," Chuck promised. He happened to catch the look on Sarah's face and he took a deep breath. "In fact, I'm hoping real soon I get to be your father on a permanent basis."

Sarah stared at him. "You already are," she said in a breathy voice.

"Sarah," Chuck began.

"Yes, Chuck?" Sarah asked, stepping closer, holding his hand, her face inches from his. Molly leaned forward, putting her face between the two of them.

"Marry me," he blurted out. "Gah," he said, dropping his head backwards and then bringing it forwards again. "I just blurted it out, instead of asking you the right way."

"Why do you want to marry me?" she asked, grinning.

"Because I can't live without the two of you," he replied. She leaned forward, and kissed him lightly.

"Kiss!" Molly yelled, clapping. Chuck pulled away, put his lips to one side of Molly's cheeks, and Sarah did to the other. They kissed her at the same time as she squealed.

"Are we interrupting something?" Carina asked as she walked in.

"No, we have the rest of our lives," Sarah said, grinning at Chuck.

"Starting now," Chuck added. She flashed a smile at him and squeezed his hand. That's when Jeff walked in, looked at Stephen and flashed. "No," Chuck muttered.

"Orion?" Jeff said.

}o{

"What's wrong kid?" Grissom asked a little later. He had just come out of the back, carrying a photo. "You look like you've seen a ghost."

"Oh, my long-lost dad has just shown up," Chuck replied. "Ellie is gonna flip, and he…" Chuck trailed off. "Sorry, can't tell you, it's a Casey secret."

"Fine by me, I know too many classified things as it is," he muttered. Chuck narrowed his eyes. "Chuck, I may have clearance, but the less I know, the better."

"I understand that," Chuck replied. "There is good news."

"I'd love to hear it, kid, but I'm not sure I believe it, because you don't look that excited," Grissom said, giving him a look.

"It is good, it's just… family." Grissom nodded. "Sarah and I are getting married, and I'm going to adopt Molly."

"Alright KID!" Grissom said, slapping him on the arm in excitement. Chuck winced a bit, but the thought of marrying Sarah brought a huge smile to his face. "Now that is some good news. Hey, remember me telling you about that woman the other day? I found a picture of her." Grissom showed it to Chuck, and he felt all of Chuck's energy drain out of him.

"This is the woman that you saw when stationed in Afghanistan?" Chuck asked for confirmation.

"Kid…" Grissom said, wondering what was going on. He caught Chuck's eyes and they looked haunted again.

Chuck turned away and looked over at his dad and Sarah. "Dad, why is mom working with Volkoff?"

The color drained from Stephen's face. "I can explain."

}o{

"My father made the Intersect, my mom is CIA super-agent the Frost Queen," Chuck said to himself, sitting on the couch in his and Sarah's apartment.

"Da," Molly said, her head lying on his shoulder.

"You don't really care, do you? You just want to be snuggled with, don't you?" he asked Molly, grinning.

"Da," she said, a grin on her face. Chuck began to tickle her ribs, and she squealed. The door opened, and they both turned as if caught. "MAMA!" the little girl yelled, throwing her arms open.

"There's my girl," Sarah said, scooping her up.

"Traitor," Chuck said with a grin. Molly giggled at him.

"You okay, son?" Stephen asked as he came in, followed by Casey, Carina, and Zondra.

"Yep," Chuck replied. "I'm getting married, and I'm going to adopt Molly."

"Fine, but I need your help saving your mother," Stephen began.

"Dad… I can't. I have responsibilities," Chuck began.

"So did we," Stephen argued.

"I get it, the government made you two do things, and that's why you left." Stephen scratched the back of his head. "Dad…"

"Not exactly, son. You see, I was working on something and, the man you know as Volkoff was created from a faulty intersect."

"Wow, so mom was sent after him. But why didn't you go?"

"Well," Stephen continued, looking more uncomfortable. "Your mother went after him, while I worked on correcting the mistake."

"They sent mom in without a fix?"

"No," Stephen replied. "She… she decided to go in herself."

"I see," Chuck replied. "Out of curiosity, when did you figure out the fix?"

"Six months ago," Stephen offered. Chuck leaned forward, his head in his hands. "But son, your mom," he began.

"Dad, you and she made choices I don't agree with… but also… I wasn't in your shoes. I'm not sure I could have made those choices, or would have, but it's easy for me to say that."

"Chuck, your mom had to know what a threat Volkoff could be… is," Sarah added.

Chuck nodded. "But would you have gone?" She sat there silently. "Let me ask a different question, would you go now?" She shook her head. Chuck turned back to Stephen. "I want you to both to be a part of my life, but Sarah and Molly have taught me something very important. You have to live with the choices you make. Life hits you… dare I say, you collide with life." Sarah groaned, and Chuck just grinned. "And your actions as a result of those collisions shape your life. You and Mom decided to leave."

"But you don't understand," Stephen insisted.

"No, you don't… but you're right, I don't either. And I'm not sure I ever will, but you did leave me and Ellie, and Dad, it hurt… it still hurts." Chuck felt a weight leave him he didn't even know existed. "I love you two. I'm not saying this to make you feel bad, I just want you to understand where I'm at in life." Chuck reached for Molly, who came to him. "I choose to stay here, and try to make this work with these two. I could have run several times. Hell, I almost did, but I made the hard choice, and not the easy one."

"I get that," Stephen said. "I do, and I can't apologize to you enough. I should have stayed but… I… I don't do people well."

"I know dad, I know," Chuck replied, with a nod. "But I'm not going after Mom. I can't leave Molly."

"Trust me, I don't want to go after him in Russia, but he won't come here," Stephen insisted.

"Why not, all we have to do is make the deal big enough," Chuck countered.

"Chuck, you'd need government backing to do that, and that… that would be way too complicated," Stephen said.

Chuck glanced over and saw Jeff. "Bull-" he stopped, feeling Sarah's glare, realizing Molly was sitting on his lap. "Shirt."

"Bullshirt," Molly said with a nod.

"It's not complicated. It's actually quite simple. I'm not saying it's going to be easy, but simple."

"You don't understand," Stephen argued.

"No, you don't," Sarah said, surprising everyone. "The son you raised will do whatever it takes to keep his family together. The son you raised will figure out another possibility that no one else would. The son you raised believes in family, those blood, and not blood, related."

"Da," Molly said, leaning her head against Chuck.

Stephen studied the three and nodded. "Okay, then what do we do?"

"We make a trade," Chuck said, grinning.

}o{

"I don't know what you expect us to do, Mr. Bartowski," Beckman said, a little while later. "We are doing everything we can to bring down Volkoff."

"What if I know a way to get the Intersect out of Jeff's head?" Chuck asked.

"What do you need?" Beckman asked, straightening.

}o{

"So let me get this straight," Sarah asked, holding her sleeping daughter. Her head was on Chuck's shoulder, as the three cuddled on the couch. "In a matter of minutes, you were able to get the NSA to agree to front enough money to get one of the biggest weapons dealers of all time to come to the US to sell weapons."

"Yep," Chuck replied, lazily running his hand through Sarah's hair, staring at the TV in front of him.

"And all you had to do was get the intersect out of Jeff's head?"

"Apparently Casey has been complaining to Beckman…a lot!"

"Do you want a big wedding?" Sarah asked, lifting up to look at him.

"All I need is you and Molly," Chuck replied. "Morgan however…" He trailed off. "Oh, crap, I haven't told him."

"You also haven't told Ellie," Sarah reminded him.

"Have you told your mom?" Chuck countered. She shook her head. "Uh-oh."

"Uh-oh, what?" The door opened and there stood Emma, with Grissom behind her. Sarah turned to Chuck. "You told Grissom before I told my mom, and before you told Morgan or Ellie?" Chuck nodded. "Go stand out in the driveway, so I can hit you with my car." Chuck just grinned at her.

"Dada, bad," Molly said, giggling. Chuck tickled her ribs, thankful Sarah had run over him those months back.

A/N: Next time, wedding bells are in the air, there's an intersect to remove, and does Mama Bartowski get home in time for the nuptials? Your guess is as good as mine. See you soon.
