So I had this idea and thought I might as well write it down. This is my first multi chapter Stargate story so be nice. :)

Oh and I've also said that Mark and Sam are twins and since I couldn't find anything about who was older and what not, I could be right.

Carter was not happy. She was sat in the debriefing for their last mission and the rest of SG1 could tell that something was bothering her. She seemed distracted, answering any questions put to her slower than normal and once Hammond had to ask her the same thing twice, something that just didn't happen when questioning Carter.

When Hammond dismissed them and left the room Sg1 all congregated around the still seated Carter. "Hey Sam," Daniel said, "What's up?"

She looked up at them, "Huh?"

"You seem a little distracted Carter," O'Neill said in a joking voice.

"Indeed," Teal'c said, inclining his head in agreement.

"What, oh I was just thinking about some stuff," Carter said shrugging.

"When are you not?" O'Neill said with a smirk, "What in particular this time?"

"I found this in my lab this morning. It got sent to my house but since we were off world Janet brought it in an told me where it was when we had our exams earlier." She handed an envelope over to O'Neill.

He took it and opened it, "High school reunion?"

She nodded, "Yeah. I don't know whether I'm going to go or not. I never really got on all that well with anyone at school and it's not like I have anyone to go with."

Teal'c raised an eyebrow and Daniel said, "How bad could it have been?"

Carter raised her eyebrow, "I was a smart blonde and an Air Force brat who had to keep moving around, add to that a twin who was a smart arse jock who always put me down since he was the older twin."

"Ah," Daniel said, "I see what you mean."

Carter nodded and O'Neill said, "I knew you had a brother but I hadn't realised he was your older twin."

Carter shrugged, "Yeah he's older by about two minutes and never let me forget it."

Teal'c nodded again then asked, "What is a high school reunion and why do you need someone to go with you?"

Daniel, O'Neill and Carter all shared a look and then Carter said, "A high school reunion is a get together of former class mates Teal'c and people use it as a chance to show how well they've done with their lives after school."

O'Neill nodded, "And Carter needs someone to go with her since it's boring if you go on your own." Daniel and Carter threw him a questioning look and he continued to say, "Trust me, the only reunion I went to I went to alone and I had a terrible time."

Carter and Daniel nodded and Teal'c said, "You will not be alone, your brother Mark Carter will be there."

"He's going with his wife and probably will just end up ignoring me the whole night."

Then O'Neill asked, "Carter when is your reunion?"

"Three weeks on Saturday Sir, why?" Carter asked, glancing quickly at the envelope.

He didn't answer her question and just asked, "Do you want to go?"

"I don't know, it will be nice to see everyone again, even if they did make my life miserable, but I did have some really good friends who I haven't seen in a long time," Carter shrugged again, obviously torn about whether or not to go.

O'Neill solved the problem for her, "Well since we're off rotation in three weeks and getting some well-earned time off, how about I go with you? If it's alright with you of course." Carter could tell from the sound of his voice that he was only half joking.

Smiling she said, "You know what Sir, I'd really like that."

Daniel and Teal'c shared a knowing smile while O'Neill and Carter just had one of their silent conversations with their body language and eyes.
