The Swarm

An alien system comprised of thousands of little space ships, rears its compositefhead and gets in the way of Voyager's route home. Janeway decides she would rather put her crew in danger than take a year to get around these things. Meanwhile, the Doctor is beginning to degrade. He is losing his memories. Kes sets about trying to get him back on course. Unfortunately for crew members, if he is re-initialized, he will lose all of his personality and memories (for instance, even knowing who Kes is). These two events are flip-flopped throughout the episode. There is some comic relief. We forget what a piece of machinery the guy was at the beginning of the series. Once again, Janeway is able to pull some amazing rabbits out of her hat.
