Sam and Kawalsky appear at area 51 and are from an alternate reality where the goa'uld have just taken over their world. They are allowed to stay, but it appears that there cannot be two Sam's in the same reality so they devise a way to save the other reality from the goa'uld by contacting their asgards. It worked...I love this episode. It was like There but for the Grace of God which was a season 1 episode, but this one was just as good -even better. It was really sweet that Sam and Jack were married in the other reality, but Jack died. It was so sweet. Seeing two alternate reality episodes and seeing that, in both, Jack and Sam were engaged or married it makes me wonder. They are meant for each other. Oh well, that's a bit off topic. I loved seeing Kawalsky again; he's such a great character. Overall, great episode, one of my favorites, and just an awesome story.
