The hair ruffle felt so familiar that Sirius didn't even think to question it.
"Duly noted," he said with an only slightly bitter laugh. "I think I'll stay in my own head though, unless there's no other option. I'm weird enough without all of this."
He shifted in the hideous but comfortable chair, contorting his body to find the perfect position where he could both lounge and give Peter his full attention.
"I'm really, truly sorry about all of that Pete. Cassandra was brilliant. You're right, she just sort looked at you and knew stuff, huh? I didn't know her as well as you did, obviously, but I liked her. I really did. She was a good person and I'll miss her. I'm sorry you never got to see where things could go with the two of you. I'm sorry you lost a friend. I'm sorry I wasn't me and you weren't you when it happened." That was the worst of it, for Sirius at least. He'd been Snape when he found out and hadn't cared in the slightest.
"Me, well, for real? I'm a fucking disaster. But what else is new, right?" He grinned, spreading his hands and gesturing to himself broadly. "When am I not a disaster? So, I'll get past this like everything else."
