Ensign Graham informs Captain Picard that the shuttlecraft (flying between the Enterprise and the planet) is out of transporter range. Yet later, the away team beams to the planet without problems. It is conceivable that at the time the Enterprise was trying to intercept the shuttle, she was still a long way away from it and again much further from the planet, even if the visual of the shuttle on screen suggested otherwise; it probably showed a close-up of the shuttle rather than its true distance. Ensign Graham's statement was therefore correct. See more »

Lt. Cmdr. Susanna Leijten: What about you?
Lt. Commander Geordi La Forge: Mm, I enjoy the bachelor's life too much.
Lt. Cmdr. Susanna Leijten: That doesn't sound like my "little brother", who always wanted advice on women.
Lt. Commander Geordi La Forge: Well, obviously you were a... a great advisor.

This is really quite well done. Five years previous to the events here, Geordi and an away team are on a seemingly benevolent planet doing research. As the story begins, a shuttle containing a friend of Geordi's burns up in the planet's atmosphere. This happens despite Picard's intense warnings. Something has happened that isn't explainable. Geordi's friend Susanna was with him on the planet and is now aboard the Enterprise. She is suddenly taken ill and convulsing. Soon her body begins to change. She is becoming another species. Geordi recognizes changes in his own body and realizes that the same thing will happen to him. The plot involves efforts to counteract this. Susanna feels helpless because in her condition she can't leave the ship, yet she is best equipped to assist in solving the mystery. This episode allows us to see an alien race that has a whole different being and it is quite fascinating.
