Sirius wasn't sure what hurt more, the confirmation that Remus and Regulus weren't just flirting but we're a thing, or the way Remus said 'you've convinced yourself you have feelings for me.' No, scratch that, he knew exactly what hurt more. Convinced yourself. As if Sirius' feelings couldn't possibly be real, couldn't ever have meant anything. It was a dismissal so thorough that it left Sirius slightly reeling. Remus had known, and not only did he not reciprocate, he didn't even care. Sirius had just convinced himself. And why should that even surprise him? He'd known for years that Remus and James could never feel for him what he did for them. It's why he'd never said anything. He knew himself well enough to avoid that kind of rejection. But this, this was so much worse. This wasn't an I don't fancy you Padfoot. This was I don't fancy you and I know that anything you might be feeling is bullshit. For a second Sirius thought he might actually break apart.
Stop it. Don't let him see. He's happy, don't fuck this up.
The walls slammed up harder than they had in a very, very long time. Sirius knew how to protect himself, was very good at blocking out the things that could hurt him. He had just always left the door open for Remus. Not anymore.
He smiled.
"Hey, it's okay. I don't know what Peters on about but you don't have to worry about that. I'm happy for you and Reggie. He's a good kid. You two are a cute couple." He pushed himself to his feet and leaned against the wall.
"Is that what this whole big thing is about? Because it's all gravy, Moony. I didn't even know you were into blokes. But you couldn't have picked a better one."
