"Well it's a very good thing that I've never befriended any sane people, then isn't it?" He grinned at the pair of them, despite the Look from Lily - he'd long since perfected his immunity to such things, unlike a certain best friend who had gone and married her.
"Oi, I'm injured you can't just go around hitting injured people. Where are the healers? I'm going to report you." He warned her. "I can't help that Remus thinks I'm funny, I am, in case you've forgotten. Hilariously funny, it's just a hazard of being my friend - something ol' Moony here has known since we were kids." He was grinning as he spoke, mostly looking at Lily though he'd peek a glance occasionally at Remus as well - he couldn't help teasing them really, he'd been stuck in a bed for days, these kinds of things built up and it wasn't healthy to keep them in.
Sirius shook his head. "And that's just about all I want to hear about my brother's creative streak, I'm sure he'll find some manner of revenge and that's all I need to know."
