A knock at the door jolted Sam out of a light nap she'd been taking on the couch. Jack appeared suddenly out of the kitchen and waved her off.

"Don't worry, I've got it."

She sat up on the couch, not really wanting to move but trying to look presentable to their guests. She couldn't get up at the moment, so she might as well look descent.

A young boy's squeals came ringing through the front door as Jack opened it to his brother.

"Uncle Jack!" The boy rushed into the front hall, throwing himself into Jack's arms.

"Hey, Squirt, where's your dad?" Jack brought him up and gave him a hug.

"Out in the car getting our bags." The boy returned the hug then turned to face the living room. "Who's that?" he asked with the curiosity only a child is capable of.

"Tommy, meet Sam. Sam, Tommy." Jack carried the small boy to the couch where Sam was sitting, waiting to meet him.

"It's nice to meet you," Tommy replied, startling Sam with his politeness. Jack caught the look and laughed lightly. "Wow, you're pretty big." Sam laughed heartily at this, jerking her out of her shock.

Jack smiled, kneeling down by the couch. He placed the boy on his knee. "Sam's going to have a baby, well actually, she's having twins. That's why she's so big," he explained.

Tommy quickly jumped off Jack's knee and hopped onto the couch next to Sam, immediately engrossing her in a conversation. Jack left to help his brother with their bags.

The dark green Jeep was parked behind Jack's truck in the driveway. As he approached he could see the dark form of his brother moving around in the back of the Jeep trying to reach all of their bags. There was a lot there for just two people, but their garment bags took up enough room.

"Need some help there?" Jack said smiling. His hands were shoved deep in his pockets as he rocked back and forth on the balls of his feet.

"Hey, Jack. Yeah actually, Tommy was supposed to help me carry in his bag, but he took off as soon as I put it in park. Where is that little Hellion, anyway?" Seamus stood up, looking around for his son.

"He's inside with Sam. They seem to have hit it off pretty well. He's probably asking about the babies." Jack's smile broadened at the thought.

Seamus shot his brother a questioning look, but they hadn't exactly spoken a lot over the last few years, even though they hadn't parted on bad terms.

"So, how long have you known Sam?" The men walked up the driveway to the front door.

"She was my 2IC for about four years, a little longer."

Seamus stopped dead in his tracks, staring at his brother. "You're marrying your 2IC!"

"I thought you knew me better than that. I may disregard the regulations when it comes to my own career, but not someone else's. Sam resigned before we got together, but I might still be court marshalled for it. I wasn't exactly informed of her resignation at the time." Jack knew that the court marshal could mean the end of his career, but to him it was a small price to pay to be with the woman he loved. Besides, he was good at a lot of things, he could always find another job.

"Sorry, didn't realize it was that Sam. What are you going to do?"

"Get married on Saturday, and see where we go from there. Sam still has..." he trailed off mid-sentence, stopping where he stood.

"What's wrong?" Seamus was immediately alert.

"Sam's gonna kill me! She's not supposed to get excited about anything." Jack ran his hand over his face in frustration. "I forgot to tell her about us."

"Wait, you mean us, us?"

"Yeah, we've been so wrapped up in everything the past few weeks I forgot to tell her about us. I better run in and tell her before you walk in there." Jack stepped away from his brother and up to the house. There was no telling what Sam's reaction might be, he needed to tell her now.

Tommy was sitting next to Sam on the couch waiting for them to bring in the bags. The look on Jack's face immediately told her something wasn't quite right.

"Jack?"

"Tommy, could you go help your dad, I have to talk to Sam real quick." He patted the boy on the head and sent him outside.

"Jack, what's going on?" Sam inched closer to him, trying to read his face.

"I just wanted to tell you something about my brother, Sam." He stopped for a moment, trying to figure out what he wanted to say. "Twins runs in our side of the family as well."

The front door slowly opened, Tommy and Seamus stepping through. Sam gasped.

"Wow. I wasn't expecting this. Why didn't you say anything sooner?" She turned to face Jack, confusion in her eyes.

"Honestly, I was so worried about your health and the boys that it completely slipped my mind. I'm really sorry, Sam." Jack wrapped his arms around his fiancée hoping to dispel the shock he knew she was going through.

"Oh, no, Jack, don't worry. I was just surprised to see he looked so much like you and nothing like you at the same time." Sam smiled into his shoulder, glad to finally be knowing the real Jack O'Neill.

"Well, I'm not sure whether to take that as an insult or a compliment. I'm Seamus O'Neill, but it can be a mouthful, just call me Sea. This is my son Tommy." Seamus stepped forward, extending his hand for her to take.

"Sorry about that. Jack never told me you were twins." Sam took his hand gratefully and pointed for him to sit. "You've been driving all day. Sit down and relax."

"Thank you. Tommy, you can go play out back." Seamus sat next to Sam on the couch, eager to get to know the woman who'd stolen his brother's heart. Jack left for the kitchen to retrieve beers for the two men.

"So, Jack's only told me a little bit about you. Are you still Air Force?" Sam turned to face her future brother-in-law. Jack handed her a diet soda and his brother a beer. He sat down in the recliner across from them.

"Yeah, desk job though." Sea sighed. "I've never actually been out in the field. I was an intel. guy."

"Wow, polar opposites, the both of you." Sam smiled between them as they laughed at her obvious revelation.

"Yep, always have been. I must admit I probably know more about you than you know about me. Well, at least the professional side of you. I, uh, categorize the information brought back by the SG teams." Sea relaxed slightly and took a swig from his beer. "I didn't realize that my brother was marrying the great Doctor Major Samantha Carter."

"Great? I think you've got your Doctor Major's mixed up with someone else."

"So, this isn't part of the reason you disappeared, was it?" he asked, indicating her obvious protrusion.

"No, but I guess the official report hasn't been turned in yet." Her eyes dropped slightly, but she quickly recovered, staring at Jack. "You didn't tell me that your brother had SGC clearance."

"I wasn't sure if he still had it." Jack shrugged and glanced at Sea.

"There was a Goa'uld on Earth. I witnessed him kill a young man's family outside a restaurant. What I didn't know was the young man was host to a Tok'ra. He killed the Goa'uld, but I didn't really understand what was going on. I mean, you expect that sort of thing offworld, but not in downtown Colorado Springs, and it caught me off guard. I ran to the nearest safe place my muddled mind could manage, that just happened to be Jack's. I didn't tell him what was wrong, but when he went into the mountain, I faxed in my resignation. When he came home, this happened," Sam smiled pointing to their babies. "I ran out when I woke up later that day and I just disappeared for six months. I kept tabs on the investigation and when I found out that everything was cleared up, I came home."

"That would be the abridged version. The full report hasn't been written yet," Jack broke in with a slight grin. He stood up from the recliner and headed towards the kitchen. "I'll get lunch ready before the munchkins get here."

"Jack? They've got kids of their own," Sea grinned.

"Yeah, so how's it been Grandpa?"

Sea laughed and threw his bottle cap at the retreating form of his twin brother, Sam's giggling filling the background.

When the laughter died down a bit, Sam decided to interrogate Sea for whatever information Jack had left out the night before.

"So why didn't your wife come up with you?" Sam asked politely. She heard a muffled cough coming from the general vicinity of the kitchen. Unfortunately, she could tell it wasn't a humorous cough.

"Which one?" Sea muttered softly. Before Sam could reply though, Sea answered her. "What has Jack told you?"

"Just some of what drove the wedge between him and your father."

"Ah, yes. For some reason, Dad felt he needed to blame Jack for Sean's existence. My first wife died when Jenny was born and Tommy's mother left us when he was three months old."

"What'd they die of?" she asked quietly.

"Carter! You ended that sentence with a preposition!" Jack laughingly shouted from the other room.

"Sorry, Sir!"

Sea just leaned back and listened to the banter between the two. It was pretty much famous to all those that worked closely with or in the SGC, but he'd never actually seen it for himself. He could see now the connection between them, and understood all the pools running through the staff. It was a welcome distraction from the direction the conversation had been taking. He decided, when Sam turned back to face him, to answer her question before she had to ask again.

"Cheryl didn't die. She felt we moved too fast and she left a year after we were married. I haven't seen or heard from her since. She's never tried to see Tommy, but I think he's better for that. Jennifer died from complications when Jenny was born," he answered somberly.

"Oh, I'm sorry."

Sea laughed at that. "You know, I've never understood why people feel the need to say that. I mean if you had told me something devastating about you, I would have said the same thing."

"So, Jack didn't tell me, how old is Tommy?"

"He just turned eleven on New Year's." He smiled as he listened to Tommy running around outside in the snow.

"He's a sweet kid." Sam took a sip of her soda, Sea just nodded his response.

"Hey," Jack said, coming back in from the kitchen. "Sean and Jenny just got here."

They could hear another voice laughing along with Tommy's in the backyard before the knock on the front door. Nobody managed to get up to answer it before the door flew open and a streak flew into the room.

"Uncle Jack! Uncle Jack! Uncle Jack!" The shouting five-year-old girl jumped up and down in the living room, staring up at him. His face broke out into a grin as he started jumping with her.

"What? What? What?"

"Daddy said you were gettin' married, and havin' kids, and I had to get a new dress, but the shoes pinch, and we have to stay at the hotel, and there's a HUGE pool, and we met some other kids, but Bridget was really shy, and Jerod's new friend is Nick, and can I meet Sam?" The little girl stopped jumping and slumped over on the couch, adding a, "Hi Grampa," to Seamus almost as an afterthought.

Jack laughed and kneeled down in front of her. "Stacy, this is Sam." He leaned into Sam, who was already sitting on the couch smiling at them.

"Hi, Sam. Is that the babies?" she asked, pointing to Sam's stomach.

"Yup," Sam answered, the smile never falling from her face.

"Hey, Uncle Jack." Sean walked in and started removing Stacy's boots and jacket, handing them up to Rhiana.

"Hey, how was the trip?" asked Jack as he stood, kissed Sam on the forehead and headed to the kitchen to set the table for lunch.

"Don't ever take those guys on a seven hour ride in the car." Sean threw his thumb over his shoulder in Sam's direction as he walked in to help Jack.

"I remember your dad taking you guys up to the cabin, thank you," Jack grinned.

"Yeah, well, Jerod decided to torture his sister the entire trip, except when he was asleep. I don't know where he gets it from."

"Gee, I wonder." They broke out into laughter, the sound causing a grin to break out on Sam's face.

A young woman set Stacy's coat and boots in the closet and came back into the living room. "Hi, Dad." She kissed Sea on the cheek and took the chair Jack vacated to fix lunch.

"Hi, I'm Rhiana." The woman's gentle smile brought more comfort to Sam, knowing she was slowly being integrated into Jack's world and family.

"Sam." She smiled back and glanced at the little girl between them. "I thought Jack said Jenny was here, too?" she questioned.

"She and Kevin are trying to bring Mya inside without letting her get cold." Sam nodded her head in reply.

At that moment the front door opened to allow the three newcomers in from the cold. The young man was holding a baby carrier and trying to make sure no snow got on the young child. Jenny stripped off her coat and moved to help her husband. The couple moved into the living room, setting the baby carrier in the middle of the floor.

"Sam, meet Jenny, Kevin and their daughter, Mya. Guys, this is Uncle Jack's fiancée, Sam." Rhiana introduced them all.

"Hi," Sam waved from the couch. She was tired from the day and didn't really feel like moving too much, the boys were active today.

"Nice to meet you." Kevin straightened up and shook Sam's hand. He sat back down on the floor next to Mya and rubbed his thumb down the sleeping child's cheek.

"She's beautiful," Sam crooned from her seat on the couch.

"Thank you," the parents both answered at the same time. They shared a smile and looked back up at the group gathered in the living room.

"When are you due?" Rhiana asked smiling at her new "aunt".

"First week in April, but really it could be before that. Janet explained the high risk and that I could expect labor as early as 30 weeks," Sam explained.

"How's Uncle Jack doing?" Jenny turned her head back towards the kitchen where Sean and Jack were finishing up lunch.

Sam shook her head, smiling and said, "I can't answer that, really. I tend to misinterpret him too easily."

"Uncle Jack is doing just fine," Jack said as he came out of the kitchen. "Lunch is ready."

A/N: Okay now we meet another section of Jack's family. hope you liked it! thanks y'all!
