Snape came to him on the sixteenth of January as Dumbledore was out of the castle.
Not to the dormitory — the dormitory was not where these conversations happened, and Snape was not a man who came to students' dormitories. The conversation happened in the corridor outside the Potions classroom at twenty past nine on a Wednesday evening : quiet, defensible, the castle's lower corridor traffic minimal at this hour, the torches at the low register of a building that had settled into its night routine.
Snape was in the position he had in these conversations — the particular composed quality of a man who had been carrying intelligence across the border between two very different worlds for his entire adult life and had developed, through the carrying, the quality of someone who knew exactly how much to say and exactly how to say it. He was not wasting time. He never wasted time in these conversations.
'He is lying low,' Snape said.
Ron waited.
'Since the failure of the Azkaban attack.' Snape's voice had the quality it had when he was choosing precision over completeness, delivering the usable information and leaving the surrounding detail for inference. 'Not the lying low of someone managing a setback — the lying low of someone who has decided the setback is temporary and is adjusting the timeline accordingly. He is not rebuilding. He is waiting.'
'For the prophecy,' Ron said.
'For the prophecy,' Snape confirmed. 'Which is proceeding slowly.' A pause. The specific pause of someone conveying something they found notable. 'More slowly than he anticipated.'
Ron was still. 'How slowly.'
'They have had people in the Department of Mysteries since October. The full strength of the Imperius network he has maintained within the Ministry — which is not inconsiderable. They have not been able to retrieve it.' Snape looked at him with the quality he had occasionally when something had confirmed a private calculation. 'The protections on that hall are more extensive than anticipated. Each attempt to access the shelf has triggered responses that have required — ' another pause — 'careful management on their side, to avoid alerting the Department's Unspeakables to the attempts.'
Ron thought about this. 'How many people know the prophecy's location.'
'Within his inner circle: all of them. The problem is not knowledge of its location. The problem is access.' Snape's expression had the flat professional quality of a man who had sat through the conversations about this and was summarising them with the compression of someone who had heard them in their original, significantly less compressed form. 'The only person who can remove the prophecy from the shelf is the person to whom it was made. He has known this since November. He has been — adjusting to this knowledge.'
Ron held this.
The only person who can remove the prophecy is the person to whom it was made.
The prophecy had been made to two people — Voldemort, who could not walk into the Ministry of Magic, and Harry Potter, who did not know where the Department of Mysteries was. This was the specific leverage point that the original timeline had required months of manipulation to exploit. Harry's connection, the dreams, the planted vision of Sirius — all of it had been engineered around the single fact that Harry could reach the shelf and no one else he controlled could.
That manipulation was what Ron had spent three years working to pre-empt.
'He's considered using Harry,' Ron said.
'He has considered it extensively,' Snape said. 'He has not yet arrived at the mechanism. The — ' the slightest hesitation — 'the connection between them that existed previously has not been available in the same form this year. He is aware of this. It has added to the frustration.'
Ron thought about the Occlumency. About the Tuesday sessions building toward the specific capability that had closed the connection before Voldemort could use it as a door. About the specific Tuesday in third year when Dumbledore had said: the most important thing we can do this year is ensure that nothing of his can find purchase in Harry's mind, and the work that had followed across two years of methodical building.
'He's not going to wait indefinitely,' Ron said.
'No,' Snape said. 'He is not.' The flat precision of someone delivering the relevant conclusion. 'The current assessment — ' again the pause of a man curating his source — 'is that patience is holding. But it is holding the way patience holds in someone who has been patient for sixteen years and has arrived at something within reach. The range of that patience is finite. When he determines the mechanism — when he believes he has found the path to Harry — he will move quickly.'
'He'll move by June,' Ron said.
Snape looked at him. The look had the quality it had in rare moments — the quality of someone who had been watching this situation from the most dangerous possible vantage point for the duration and had arrived at a specific position on it. Not approval, which was not the register Snape used. Something more careful than that. 'That is my assessment also,' he said.
Ron looked at the wall.
He thought about the shape of the next five months. January's training — the depth work, the apparition sessions, the ritual in March. The career sessions. The OWLs in late May. And underneath all of it, running parallel and invisible to most of the castle, the specific question of when Voldemort would find his mechanism, and whether Ron would be ready when he did.
He was ready now. He had been essentially ready since October and had spent the months since becoming more ready in the specific ways that October's readiness had not yet covered. The preparedness was not the question.
The question was whether Voldemort's timeline would coincide with the specific conditions that were needed — the Horcruxes reduced to the Cup, the Death Eaters accessible, the Ministry in Amelia's hands rather than Fudge's. All three. They needed all three.
'The Cup,' Ron said.
Snape's expression registered something that was not surprise, but was the acknowledgment of someone who had expected to be surprised and had not been and was noting this. 'Bellatrix Lestrange has not accessed Gringotts since August. She does not wish to risk recapture, especially since Lucius was killed.' A pause. 'This alone has prevented the spread of our knowledge of the horcruxes to Voldemort'
Snape was quiet. Outside the corridor, the castle settled further into its night register — a torch guttering briefly in a draught, the distant sound of something moving through the upper floors that was probably Peeves and was the castle's problem rather than theirs.
'One further thing,' Snape said.
Ron waited.
'He is not communicating freely with the inner circle.' The specific care of a man reporting something he had parsed for implication over several weeks and was delivering the implication rather than the raw material. 'Since Naginis death. The communications are more — guarded. The inner circle is aware of this. They are not discussing it. They are carrying it with the specific quality of people who understand that asking about it would be the kind of thing that was noticed.' Another pause. 'He is suspicious.'
'Of the intelligence leaks,' Ron said.
'Of the pattern of his plans not proceeding as intended.' Snape's voice was level. 'He has not identified a specific source. He is not in a position to identify a specific source — the divergences between his expected timeline and the actual one are widespread enough and varied enough in origin that they do not point toward a single person. But he is aware that something is different. That the resistance he is encountering is organised in a way that surprises him.' He held Ron's gaze for a moment. 'He used the word prepared in January. In the context of the Azkaban operation.'
Ron thought about this.
Prepared.
He had been building this for four years. The intelligence, the training, the rituals, the relationships, the specific accumulation of small correct decisions across forty-eight months of consistent and unglamorous work. And Voldemort, across the country, sitting in the specific quality of someone who had returned from a kind of death and was finding that the world had used his absence to become more difficult, was beginning to understand that the difficulty had a shape.
Was beginning, dimly, to understand that the shape had an origin.
'Thank you,' Ron said. 'For the full picture.'
Snape left. The corridor returned to its ordinary late-evening quality. Ron stood in it for a moment and thought about the specific word — prepared — and thought about what it meant that Voldemort had used it, and thought about the five months between January and the Department of Mysteries, and found himself, standing in a corridor on the lower floor of Hogwarts at half past nine on a Wednesday in January, something that was not quite ready but was the thing adjacent to it.
The thing that came from having done the work.
He went to bed.
