Oh, of course, Harry thought, saying nothing as he listened. He was surprised at the offer, and felt a bit guilty at his previous doubts, the hesitation that had come the moment Dumbledore had mentioned Severus' name. It had felt so much like he remembered from when he was a teenager, the question if Severus would want to hurt him and Ginny. But now he was offering.
"Professor Dumbledore suggested it already," he said. "I was going to come talk to you in the morning. Ask if you were willing," he said. "I appreciate the offer."
