I remember loving Hathor. She had that cheeky Suzie Plakson quality. Just starting rewatching S1 so doubt will ever catch you up. Only thing struck me about pilot two-parter is I could swear my blu-ray version is different to DVD one I saw few years ago. The effects not only look better (duh) but actually slightly different, as does the whole show. Maybe it's just time/nostalgia, or maybe one of the SG experts knows if there are differences.
You might have the "final cut" version. Brad Wright pulled a 'George Lucas' on it not so long ago.
