In the Pilot episode, "The Cage". I was always a little confused about something. Maybe someone here can clear it up for me.
When Christopher Pike was shown Vina's true appearance towards the end of the episode, Vina stated that the Talosians found her almost dead as the solo survivor of her crashed ship and they were able to repair her physical damages. However, they had never seen a human before and had no basis of putting things back together correctly.
The Talosians were masters of creating illusions. These illusions were derived from the Talosians reading your mind and generating illusions from the depths of your memory...even some things you probably had forgotten. If this is so, why couldn't they read Vina's mind to at least see how she looked prior to the crash and try to restore her back to that appearance? Also, why couldn't they read her mind to draw out all of the basic biological and physical science information that was in her brain from her school years to assist in their attempt to restore her back to her previous self?
