Sirius was glad Harry was back. There were presences he counted on as being constants here, and he hadn't realized he had thought of Harry was one of them until the boy was gone. Still, it was a bit strange. Perhaps it was the absence of James, which Sirius felt all the more keenly now that his son had returned, but he hadn't. Or, perhaps, it was simply that Harry was older -- and Sirius didn't remember him any better, but Harry had to know him better this time.
He knew it was a good thing -- a great thing -- that they all had this future to look forward to. Cici and Johnny got just about as normal a childhood as a kid coming out from a Lupin, Black, or Potter could hope for. While Sirius did look forward to it, it did always seem to emphasize everything he didn't have yet -- all the things he was devoid.
Still, he wasn't stupid enough to pass up a chance to spend time with his godson. He readily accepted the invitation. It didn't take him long to find Harry when he walked into the pub -- still looking a ridiculous amount like James.
"Getting started without me?" Sirius teased as he walked up beside Harry.
