Harry smiled. "I didn't think you would be," he said, before sighing and looking at Al. "Severus knows," he said. "You can talk to him about it if you want as long as no one is around to hear you. Including any portraits, ghosts or house elves. Or Peeves," he added. He could only imagine the chanting.
He looked at Al, surprised at the request, but he didn't see the need to argue. "Of course. I'll figure something out." He'll just open a vault in his and Al's name and save the money there for him. Al didn't need to know until later, if at all. He could use whatever money there was to buy him a place to live when he wanted to move out again.
