Wait, Regulus brought the Dark Lord down? What the Bloody Hell? Sirius almost made a snarky remark about how his baby Godson axtually did that, thank you very much, but he knew thr conversation would be over the moment he did. Instead he filed tidbit of information away. He'd ask Dumbledore about it later.
"I have Mother's portrait all ready for you to take, since I know how much you'd want it,"
Sirius actually laughed at loud at that.
"Oh yeah, hand it over. I've always wanted a bat shit crazy painting to scream at me all day and insult every choice I've ever made."
Sirius took a moment to actually look around.
"Now that you mention it, the stink of Evil is not nearly as prominent as it was when I was here last. Good job, kid."
