The Doctor injures Zahir and kidnaps Kes after developing an evil alter ego while grafting new personalities into his program. Kes considers leaving Voyager to be with Zahir, but later decides against this. In "Before and After", an episode in the third season, Kes lives short periods of her life in reverse order, starting with her death and ending with her birth. In this alternative timeline, she is romantically involved with Paris, and they have a daughter, Linnis, who marries and has a son with Harry Kim. During this timeline, Kes participates in Voyager's year-long battle with the Krenim, which takes place in the season four episode "Year of Hell". She is infected with particles from a chroniton torpedo during the Krenim attack; Paris speculates that this exposure to chroniton radiation is the reason why Kes is irregularly jumping back in time. When the Doctor brings Kes back to the present, she documents information about the Krenim and their future attack. At the end of the episode, Tuvok says Kes has seen only one possible future for Voyager. During "Scorpion", Voyager becomes entangled in a major conflict between the Borg and Species 8472. Partially due to her exposure to the powerful telepathic influx of Species 8472, Kes begins to evolve into a different state of being. In "The Gift", she realizes she can no longer remain aboard Voyager, as her powers threaten to destroy the ship. She uses her newly acquired powers to hurl Voyager and its crew safely beyond Borg space, 9,500 light-years closer to Earth, before turning into living energy. Kes revisits Voyager in "Fury", in which she is near the end of her life cycle and experiencing memory loss. She mistakenly believes that Janeway kidnapped her from Ocampa, and she travels back in time to negotiate with the Vidiians, promising to help them access the ship to harvest the crew members' organs if they take her younger self home. After this plan is stopped, the younger Kes creates a hologram to remind her future self about her affection for the crew and how much they had cared for her. After seeing the hologram, the older version of Kes says goodbye to the crew before taking her ship back to Ocampa. Non-canonical appearances Kes appears in non-canon novels and short stories adapted from Star Trek: Voyager. In Christie Golden's 1997 book Marooned, an alien kidnaps Kes, and during
