Personally, I'm a Carter/naquada reactor OTPer. She never looked at anyone or anything the way she looked at that baby ... ;-)
However, I could quite easily be a closet Carter/Amabssador Joe shipper. Somehow, they fitted really well. He respected her, as a woman and as a professional career-focused woman; they could have been happy, I'm sure. And on a perfectly shallow note, they looked great together.
Carter/Lee ... oh yeah...the sniping, the scientific pillow talk, the technobabble as sex ... someone needs to write it. :-)
