When getting ready for Paris' surgery, The Doctor states that he is sterilizing his hands, which makes little sense: he is a hologram that could just change his density to nothing, remove any germs on his surface, and then reinstate his solidness. Furthermore, after the sterilization is complete, he touches the control pads on different pieces of equipment, which have been touched in the past by other people who were not sterilized and would nullify the effort of sterilizing his hands.

Doctor, Doctor, Give Me the News
22 August 2018 | by HitchcocSee all my reviews

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.
