Nods and tell her of his plans to takeover Hogwarts and kill Dumbledore

He let out a high, thin chuckle, a sound that grated on the nerves. "Clever, Rose. Very clever. To think that my enemies could be so bold." He traced a long, pale finger along a silver spine on a nearby shelf. "But I have anticipated this. I have laid my own trap. Hogwarts... that nest of Mudbloods and Muggle-lovers... will soon be mine. Dumbledore will fall, not by an outside army, but from within."

"Yes master. He will fall." Rose said.

Voldemort's eyes gleamed with feverish light. "The old fool trusts. It is his greatest weakness. He trusts in the loyalty of his staff. He trusts in the power of ancient magic. He will be in for a rude awakening. A key figure, one he has protected for years, will be the instrument of his undoing. And when the Headmaster is gone, the school will be ripe for the taking. A new age of magical education will begin. One that teaches true power."

Rose ask. "Who do you mean?"

"Snape of course. He is the key. The old fool trusts him. The old fool is wrong. The Dark Lord is always right." Voldemort looked at Rose "I am giving you this information because you are mine now. You will not leave this castle. You will be protected and you will watch your children grow. You will watch my victory from the safest seat in the world." His gaze was possessive, triumphant. "Do you have any objections, mother of my heirs?"

Rose felt the floor tilt beneath her, a dizzying vertigo that had nothing to do with the life shifting inside her. This was the crucible. Every path forked from this single, terrible moment. She could see them all laid out before her, three futures branching from this room.

The first was the easiest. A few words. A simple betrayal. "My Lord," she could say, letting her voice tremble with righteous fury, "you are mistaken. Snape is still Dumbledore's man. He plays you for a fool." She would be rewarded. Voldemort's favor, a life of gilded safety as the treasured mother of his line. She would watch the world burn from a velvet throne, and Snape would be ash.

The second was more complex. A gambler's throw. "My Lord," she could whisper, her eyes filled with a dark fire, "Snape is yours, but his resolve wavers. Let me be the one to turn him fully. I can break the last of his old loyalties and forge him into a weapon worthy only of you." It was a power play. It placed her as his temptress, his queen, the one who could break even the most stubborn will. It was a lie that might just become true if she played it well enough, twisting Snape's desperation to her own ends.

And the third... the third was a razor's edge of silence. To keep this knowledge to herself. To carry it back to Snape like a poisoned dagger and let him decide how to use it. It was the path of conspiracy, of shared risk. The path where their lives were tangled together in the dark, wholly dependent on the other's nerve.
