"Yeah. Yes. Exactly. Best friends. Less stupid. All of that."
He nodded, patting Peters head fondly before settling against his shoulder. He never saw anything weird about being affectionate with his friends, and it was nice being close to Peter again.
"Yeah, you should talk to him. And trust me, I know all about pushing people away so you don't get hurt. But... Maybe he'll surprise you. If you're honest, and open. Talk to him like you're talking to me." James had been badly hurt, but that didn't mean he couldn't forgive. Sirius knew James, and he knew how hard it was for him to be angry with Peter. "Whatever happens you can talk to me about it."
Sirius definitely did not want to talk about James or Remus. At least, not in the way that Peter was implying. Sirius knew his friends loved him. He also knew they weren't in love with him, and he was just starting to really come to terms with the fact that he might be totally in love with both of them and how utterly futile that was, and he could really only do so much self reflection in one day.
"Very funny," he said, playing along with the joke they both knew wasn't a joke. "But thank you."
