Brigadier General Jonathon 'Jack' O'Neill. The one person that Samantha Carter trusted, not only with her life, but also with her heart. The only person in the world that she wanted to go to with her problems, but the one person that she couldn't. Not when he was the whole reason for the problems in the first place. Pete had never liked her teammates, but he hated Jack the most, for what he represented, and later what he was. The father of her children, and the only person she would ever love.
Pete never really knew anything, but Sam knew he had never really bonded with Grace and Jenny. However, when her son was born, the one that was sure to have his daddy's brown hair, and mischievous eyes, she knew that Pete would never accept that it was his child. She didn't know why she'd done it. Grace and Jenny had been conceived about 3 months after she and Pete married, on one drunken evening when Janet had thrown her retirement party. Jack had come up to her, after Pete had left, and told her how stupid he thought she was being, with the aid of a bottle and a half of scotch in his system. She had agreed with him, honesty brought on by too many beers, but told him she couldn't give up on Pete. Not after he was the only guy in her life that had survived the "black widow Carter" curse, and had stuck around when he found out what she did. Jack had looked at her, really looked, with those deep brown eyes that seemed to pull at her, and said, "What about me?" She didn't remember how they had ended up in Janet's guestroom, how their clothes had been removed, but she remembered his body like it was an hour ago, discovering every scar, every inch like it was a piece of alien technology that she was studying in detail.
When she missed her next period, she knew immediately that the baby would be Jack's. Not only did Pete wear condoms, she knew deep in her heart that she would only ever want to have Jack's children. This felt so inherently right, that it couldn't be Pete's. She prayed that Pete wouldn't realise, that he'd buy her excuse that they must have used a faulty condom, and when her girls had been born, she'd let out a breath that she'd been holding for months when they looked like her.
But this little boy inside her hadn't been conceived in some drunken night of passion. Well, she'd been sober. Jack had been so drunk when she got to his, that he thought it was a dream. She'd gone to him to drop off a Simpson's DVD that she found when clearing out some old junk. And he'd been hammered, and when he reached for her and asked her to stay, and said that it was "my dream and I'll be damned if I let you get away with leaving in dreams as well as in real life", she turned around and melted into his arms without a second thought. It was only when her period was late again that she realised that she was pregnant. And when the doctors had told her it was a boy, she knew she had to run, because if Pete hit her, she accepted it, but she'd never let him hurt one of her children.
