He found her naked on the floor of his living room and experienced a profound sense of deja vu. When she regained consciousness, she explained that it was simply a brain hiccough that prevented him from remembering he had seen her thus several instants earlier. He smiled and nodded agreeable, but when he buttoned her into one of his dress shirts and lifted her in his arms, he knew he had done it before.
It took less time than it had for Vala. She had saved their collective asses -- if three galaxies to her credit could even be counted as ass-saving anymore -- after all. Anyway, they let him do it, give her her patch.
"Welcome to SG-1, Morgan," he said, ignoring the way her eyes brightened when she smiled.
He ignored, denied, repressed, flat out refused to think about the sparks that flared between them every time he gestured to her and said something like, "Morgan, explain to these nice people why they are going to do exactly what I just said."
And she ignored, denied, repressed, flat out refused to think about the fact that she had halted her progress toward Ascension when her powers re-emerged, because she could "kick the ass" of anyone who threatened the SGC -- and Cameron -- from the physical plane without fear of censure and still with little more than a flicker of thought.
Everyone ignored, denied, rperessed, flat out refused to talk about the relieved embraces at the end of missions, the locked gazes that went on just a little too long, and the silent language of eyebrows, lips, and fingertips they shared. Everyone except Vala, who'd heard the stories from Daniel, and took to calling them Jack and Sam (mostly behind their backs) -- much to the irritation of the actual Sam. At least until she got posted to Atlantis (the second time) and they all said goodbye in the wee hours of the morning after her and the General's wedding.
Then Cam and Morgan were the last to leave, and Samantha Carter O'Neill saw them in the moonlit garden, not talking the way she and her new husband had always done. "Hang in there, Sam," she whispered, knowing Morgan would hear her whether she spoke the words aloud or not.
Hang in there, she said, and through Wraith, and Replicators, and seriously pissed off Furlings, they did.
Eight years later, Cameron made General and Morgan was named commander of Alexandria in the Andromeda galaxy. Cameron kissed her goodbye (for the first time they both actually remembered). They never married, much to the consternation of Wendy Mitchel, but her twin granddaughters -- Samantha and Jacqueline -- made up for it.
