CRUSHER: Well, according to his medical records and psych profile, he's very high on the ESP scale. A sort of prodigy.
PICARD: A prodigy? In what sense?
TROI: Well, in most Betazoids our telepathic gifts develop at adolescence.
PICARD: You mean you're not born reading minds?
TROI: No. Except for some reason that no one understands, occasionally a Betazoid child is born different.
PICARD: How different?
CRUSHER: Born with his telepathic abilities switched on.
TROI: Most Betazoids born like that never lead a normal life.
CRUSHER: The noise of other people's thoughts and feelings must be overwhelming, incomprehensible, especially to a child.
TROI: And painful. Early diagnosis and special training did help Tam adjust, but he has some problems.
PICARD: You mentioned a hospitalisation.
TROI: For stress. Repeatedly, throughout his life.
CRUSHER: I always wonder what holds one person together through that kind of struggle, while another goes under?
PICARD: Yes, well, he's evidently done more than hold together. He's the indispensable man. The Federation's finest specialist in communication with unknown life forms.
CRUSHER: The more unusual a life form is, the better he likes it. His personnel file shows that he's gravitated toward assignments that isolate him from other humanoids.
