Ghanima spoke in one of the ancient languages they shared in genetic memory: "So today we have a grandmother."

"It bothers Alia greatly," Leto said.

"Who likes to give up such authority?" Ghanima asked.

Leto laughed softly, an oddly adult sound from flesh so young. "It's more than that."

"Will her mother's eyes observe what we have observed?"

"And why not?" Leto asked.

"Yes... That could be what Alia fears."

"Who knows Abomination better than Abomination?" Leto asked.

"We could be wrong, you know," Ghanima said.

"But we're not." And he quoted from the Bene Gesserit Azhar Book: "It is with reason and terrible experience that we call the pre-born Abomination. For who knows what lost and damned persona out of our evil past may take over the living flesh?"

"I know the history of it," Ghanima said. "But if that's true, why don't we suffer from this inner assault?"

"Perhaps our parents stand guard within us," Leto said.

"Then why not guardians for Alia as well?"

"I don't know. It could be because one of her parents remains among the living. It could be simply that we are still young and strong. Perhaps when we're older and more cynical..."

"We must take great care with this grandmother," Ghanima said.

"And not discuss this Preacher who wanders our planet speaking heresy?"

"You don't really think he's our father!"

"I make no judgment on it, but Alia fears him."

Ghanima shook her head sharply. "I don't believe this Abomination nonsense!"

"You've just as many memories as I have," Leto said. "You can believe what you want to believe."

"You think it's because we haven't dared the spice trance and Alia has," Ghanima said.

"That's exactly what I think."

They fell silent, moving out into the flow of people in the central passage. It was cool in Sietch Tabr, but the stillsuits were warm and the twins kept their condenser hoods thrown back from their red hair. Their faces betrayed the stamp of shared genes: generous mouths, widely set eyes of spice addict blue-on-blue.
