Since Kes left Voyager and Neelix is no longer the jealous jerk of the first seasons and he also no longer wears that ridiculous chef's hat, he has become much more bearable and profound. His warm-hearted and empathetic nature towards the crew comes through much better and is not constantly overshadowed by mistrust and a lack of self-confidence.
In this episode, Neelix tells the Borg children how an alien creature has crippled half of Voyager and Janeway is now trying to find a new home for this creature. The scenery has something of campfire romanticism - when scary stories are told in the darkness by the light of the fire. Through flashbacks and constant interruptions and questions from the children about the events, including their own interpretations, the plot develops step by step. You almost have the feeling of being there and listening to Neelix's story. The whole thing has something of a sci-fi mystery horror about it.
However, I wonder why Janeway and the senior officers are keeping such a secret about the stowaway. Voyager has encountered strange beings countless times and has had one or two uninvited guests on the bridge. It would have made more sense to inform the crew about what happened on the ship and that they are looking for a new home for an alien energetic, non-corporeal life form that has temporarily made itself comfortable on deck 12. After all, they are explorers and first contact is one of their goals.
