ET- Telepathic Shield

  E.T. worked along, most upset. If this fate, the edge of which he’d spied, were ever to unfold, he would not just be farmed out, he’d be cast out, forever, from the planet itself.

  “A strange thought attends you,” said Botanicus, appearing beside him in the row.

  E.T. quickly wrapped a mental sheath around himself, black and thick, folds impenetrable to all—except Botanicus, for whom it was transparent, like leaves held to the sun, through which he saw the mad configuration in E.T.’s brain. “There have been voyagers like you in the past, dear Doctor, who fell victim to the narcosis of the stars.”
