Stargate Atlantis

Dr Keller is overtaken by an alien consciousness known as Neeva, which assumes control of his body and mind. Neeva, a self‑confessed thief, reveals that the switch was made possible through the use of ancient technology, and that this ancient tech had been hidden for centuries.

is a programme presented in the form of an episode. It belongs to the genre of episodic storytelling and centres on a single, self‑contained narrative that unfolds within its runtime. In this particular instalment, Dr Keller finds herself possessed by an alien consciousness that calls itself Neeva. The takeover isn’t a benign encounter; instead, the alien presence commandeers Keller’s mind and body, driving the action of the episode forward. Neeva soon reveals that it isn’t merely an observer but a thief, having appropriated something valuable during the possession. The alien admits that the means of the switch – the process that allowed the consciousness to inhabit Keller – relied on technology of an ancient origin, suggesting a link between the theft and long‑forgotten scientific artefacts. The episode therefore combines a personal invasion with the intrigue of a heist, all underpinned by the revelation that ancient technology facilitated the alien’s intrusion. This blend of bodily takeover, criminal intent, and historic tech forms the core of the story’s progression.
