Bliss

After five years, discovering a wormhole leading directly to Alpha Quadrant and Earth elates the crew beyond belief, but Seven Of Nine remains unconvinced that this is real. She suspects there is something wrong with how quickly and easily the Voyager's crew accepts the appearance of the phenomenon. To help her cause, she recruits Naomi Wildman, the Doctor, and an alien pilot named Qatai to stop the ship from entering and from being digested by a large bioplasmic space-dwelling lifeform.
