Barclay appears and tells him that his entire time on Voyager is an elaborate simulation, and he’s really a holo-engineer by the name of Zimmerman on Jupiter station in the Alpha Quadrant, who has been trapped on a holodeck for six hours. If he does not destroy Voyager’s warp core and end the program soon he will die.
