The amusement was gone in a heartbeat. "I'm not even worried about that. Creatures we can deal with. Dementors, vampires, dragons, those are things we can take. People scare me more. Death Eaters." He put his wand in his pocket. "There was something that I wanted to talk to you and Sirius about, something that Marlene brought up: legilimency." He had avoid thinking about, too busy with other research, but he had looked into it a bit.
"I didn't know it was something wizards could do, not until she said it a couple of weeks ago. I think that's what Bella did. I kept thinking to myself that maybe it wasn't my fault. She never really asked me anything she didn't really know. There had to be someone else," he said, frowning. "I was so sure that I never gave them anything, not until- I must have told them that, because of how the Fidelius works, but I always figured that I hadn't really done any damage, but if she took it from my head?" He sighed. "I'm not even sure what I'm saying. That bitch could have gotten the information without threatening my family, without me even knowing, but she wanted me to know. She enjoyed it." God, if she ever came back, he'd kill her in the most painful way.
He smiled at little. "It's ... I like him, Harry I mean. Despite Petunia and her awful husband, despite everything that happened to him, he's a good man. He's good because of you and Lily. You must be really proud of him. Even if we don't pay attention at times," he added, with a chuckle.
Peter cast spells on both sides of the corridor to ensure that no one would accidentally walk by. "Come on, let's go find Remus," he said, putting his wand away. "He's happy, though. The way he talks about Regulus- He's happy, and I want him to be happy."
