Between the lines - STARGATE SG1

During season 9 and 10 there are many allusions to the Sam/Jack couple, but what is really going on between the lines? This is my very first Fanfiction, I'm a French native speaker, so this fanfic is a translation, i'm not fluent in English, so the translation might be a little awkward sometimes, sorry about that. I'm looking forward to your opinions and comments.
