The young son of the bookseller Henry Janeway in Portage Creek, Indiana, in December 2000, who befriends the stranded Shannon O'Donnel and shares her enthusiasm for the future.
Jason Janeway appears in the fifth-season Voyager episode 11:59, played by Bradley Pierce. He helps his widowed father run a bookshop that is the last business in town holding out against the builders of the Millennium Gate.
When Shannon O'Donnel's car breaks down outside, Jason is quick to make her welcome and takes to her talk of computers and space, interests his father distrusts. He is fond of Henry but frustrated by his refusal to look anywhere except the past.
Jason's wish to see the Gate built, and his obvious liking for Shannon, are part of what finally moves Henry to sell before the midnight deadline. In the twenty-fourth century Captain Janeway learns that the family story she grew up with was much embellished, and keeps a photograph of the three of them.
