Well, Star Trek writers like the idea of an alien species that takes control of someone else's body and possesses it or pretends to be someone else. The good old impostor story, which Philip K. Dick already wrote in the 1950s - a classic in Sci Fi.
In this episode, an alien is able to switch bodies and chooses Tom Paris. Although Tom then acts like a jerk, no one even imagines the eventuality, that something must be wrong with him. Although they just met an alien guy in a high tech ship right before Tom became all weird and the crew has been possessed multiple times before by alien species already. Not eben B'Elanna becomes suspicious. So much for judge of character. Especially on a highly sophisticated star ship with its rules, and regulations - it is amazing that someone that doesn't know Starfleet or how to operate Voyager is able to blend in without anyone noticing that he is an impostor. Of course, the Voyager crew manages to put everyone back in his or her body again, thanks to the doctor that just achieves anything.
What is strange in this episode: They encounter this space ship that can fold space to travel vast distances really fast. But no one seems to be eagerly excited to maybe use this technology to retrofit Voyager and fly home faster. They try to build this technology in one of the shuttles but that's about it. No more word later about this fascinating piece of technology, that could get them home in no time or at least save them a lot of trouble with other alien species on their trip.
