Re: Astoria/Sirius
Sirius had stayed with James after everything, but eventually they'd split up - people wanted to offer their sympathies to James and Sirius wouldn't stand there in their way, he'd rescue James of course if it got to that point, but for the time being he left him on his own to talk with relatives and friends and anyone else who had come to the service.
He'd found a few people around that he chatted with, though really Sirius hadn't been up to any serious conversations at the moment, he even made quick apology to Ron and Hermione - even if Sirius was still convinced he'd end up punched in the face again if he talked with the man long enough.
And eventually he settled on Astoria, after the wedding and everything that had happened he couldn't imagine too many of the Weasleys were in a hurry to talk to her - and as he'd been reminded at the wedding, and with the birth of her children, she was family. And so he made his way over to her.
"You look surprisingly nothing like a woman who has just recently given birth to twins." He commented - surely there was some magic at work there. "How are Carina and Cepheus?"
