“Or are you too sunken in this uncanny habit to care whether your sister breaks her heart?” Farris demanded.

Berreau flared. “You’re a smug pair! You treat me like a drug addict, without knowing the wonder of the experience I’ve had! I’ve gone into another world, an alien Earth that is around us every day of our lives and that we can’t even see. And I’m going back again, and again.”

“Use that chlorophyll drug and go hunati again?” Farris said grimly.

Berreau nodded defiantly.

“No,” said Farris. “You’re not. For if you do, we’ll just go out there and bring you in again. You’ll be quite helpless to prevent us, once you’re hunati.”

The other man raged. “There’s a way I can stop you from doing that! Your threats are dangerous!”

“There’s no way,” Farris said flatly. “Once you’ve frozen yourself into that slower life-tempo, you’re helpless against normal people. And I’m not threatening. I’m trying to save your sanity, man!”

Berreau flung out of the room without answer. Lys looked at the American, with tears glimmering in her eyes.

“I fear not,” the girl whispered. “It has become a madness in his brain.”
