He said: "The Lady Jessica was trained to rule."

Ghanima nodded. "Why does she choose this time to come back?"

Alia scowled. Then: "Is it possible she merely wants to see her grandchildren?"

Ghanima thought: That's what you hope, my dear aunt. But it's damned well not likely.

"She cannot rule here," Alia said. "She has Caladan. That should be enough."

Ghanima spoke placatingly: "When our father went into the desert to die, he left you as Regent. He..."

"Have you any complaint?" Alia demanded.

"It was a reasonable choice," Leto said, following his sister's lead. "You were the one person who knew what it was like to be born as we were born."

"It's rumored that my mother has returned to the Sisterhood," Alia said, "and you both knew what the Bene Gesserit think about..."

"Abomination," Leto said.

"Yes!" Alia bit the word off.

"Once a witch, always a witch - so it's said," Ghanima said.

Sister, you play a dangerous game, Leto thought, but he followed her lead, saying: "Our grandmother was a woman of greater simplicity than others of her kind. You share her memories, Alia; surely you must know what to expect."

"Simplicity!" Alia said, shaking her head, looking around her at the thronged passage, then back to the twins. "If my mother were less complex, neither of you would be here - nor I. I would have been her firstborn and none of this..." A shrug, half shudder, moved her shoulders. "I warn you two, be very careful what you do today." Alia looked up. "Here comes my guard."

"And you still don't think it safe for us to accompany you to the spaceport?" Leto asked.

"Wait here," Alia said. "I'll bring her back."

Leto exchanged a look with his sister, said: "You've told us many times that the memories we hold from those who've passed before us lack a certain usefulness until we've experienced enough with our own flesh to make them reality. My sister and I believe this. We anticipate dangerous changes with the arrival of our grandmother."
