When Snape regained consciousness, he found himself in the infirmary at Hogwarts. 'How did I get here,' he wondered.
"I see you are finally awake Professor Snape," Madam Pomfrey said. "If you will take your potion, I will go and get the headmaster. He wanted to speak to you when you came to."
"How did I get here? What happened?" Snape asked.
"Just take your potion, Severus. Have some chocolate too. You'll get your questions answered in time." Pomfrey left to get Dumbledore, leaving Snape to look around the infirmary.
'It's been a long time since I was here as a patient,' he thought. He looked around and could see that the Muggles that had been tortured along with him were also there. "Muggles at Hogwarts," he said aloud with some disgust. "Whatever next?"
"I was hoping you could tell me, Severus," came the voice of Dumbledore. Snape quickly jerked round and saw him entering with Pomfrey. "What happened?"
"He summoned me, Albus. I had to go. When I arrived at his location, he suggested that to prove my loyalty I would have to deal with the Muggles. It was just a cruel trick, though. He knew I had betrayed him."
"Then why are you still alive?" Dumbledore asked seriously. "Voldemort has never been known for his mercy to those who betrayed him."
"He wanted me to come back here. He gave me a message for you," Snape said quietly, coughing occasionally as a result of his treatment at the hands of Voldemort. "They will be here very soon; I would think two days at most. He and the Death Eaters took great delight in torturing the five of us."
"You know who the Muggles are, Severus?"
"I can guess. One's obviously Granger's mother while another is probably her father. As for the other two, anybody who's talked to Hagrid knows they are the Muggles Potter spends his summers with. I'm not sure why they were kept alive though."
"Headmaster," Pomfrey warned, "Don't talk to Severus too long. He needs his rest. I haven't seen anybody tortured more since the first war."
"Of course, Poppy. I won't be much longer," Dumbledore responded. "Severus, did Voldemort say how he knew you were no longer his loyal servant?"
"He said he never trusted me since he returned. And he suggested he has one or more informants inside Hogwarts," Snape replied.
"I see. Very well Severus. Thank you for your information. Now obey Poppy's instructions and get some rest. I will need you healthy when the battle begins." With that, Dumbledore left and Madam Pomfrey began to fuss over Snape and her other patients. Soon enough, Snape fell asleep once more."
