This episode is unique from the others in the series as it seems to conclude the role of Daniel Jackson in the SG-1 team. In Season 1 at the start of the series, Daniel loses his wife to Apophis and strives to get her back to him which is his main objective in joining the SG-1 team. In this episode, he finds her, but ends up losing her for good. When you look over the episode from the start to the end, you realize that everything that happens in between was part of Daniel's dream. He has what is in essence, a dream within a dream. As his wife attacks him with a beam projecting into his head, he experiences what could be called future timelines that would have happened after his attack. During the dream experience, his wife is able to communicate to him her request for him to find and protect her baby created by the joining of two Go'auld hosts. At the end of the episode, she is killed by Teal'c who intervenes on her attack on Daniel. Daniel's dream allows him to avoid repeating the experiences in his dream and to focus on finding his wife's baby. The search will climax in the episode "Maternal Instinct" later in the season.
