"I know," she said, looking at Remus and Sirius, then back up at James. "I can go to Professor Slughorn and get a potion for Sirius. Just something to calm him, give him some of his strength back. He could just lay down on the couch here, by the fire." It seemed like a good compromise, something she hoped would work for everyone.
