In the episode Natural Law Seven is stranded on a planet with Chakotay. She's anxious about getting stuck there with the natives and she goes off alone to find a part of the ship they need in order to be rescued. In contrast Chakotay trusts the situation and is fascinated by the local people.
On her mission she accidentally loses her tricorder and reality suddenly sets in. She's a control freak and now she's all alone in a dangerous jungle and it's getting dark. In her despair she regresses back to her childhood self, which is all she truly has left. She's a helpless 7 year old girl who's going to die.
A native girl finds and saves her. Seven manages to get her to understand her mission and they continue together.
However the girl takes her to see a beautiful waterfall. At first Seven is confused and upset because she needs to find the part. However the girl is adamant about it and eventually she starts to see the beauty. It's exactly what she needed and the girl knew that all along.
I think this moment can teach us a lot about ourselves and our relationship to technology and beauty.
