It's obvious that Kieren's more than a little nervous about this whole thing and Sirius can't say he blames him at all. It has less to do with having a strange boy in his bed and far more to do with the fact that he's suddenly fully human again, no longer undead or whatever it is he'd been before. He's back to breathing and bleeding and eating and simply being alive. It won't take long to notice, he's sure. Even now, Sirius remembers too well the layers of gunk Kieren would slather onto his skin to make himself appear normal, the contacts he'd wear and the way he'd try to cover up.

He still tries to cover up a bit, but Sirius has learned that's simply Kieren's terrible fashion sense and not really a factor of being partially dead.

So he follows quietly, linking his fingers with Kieren's until they've made it downstairs and then slipping away a bit when his mother approaches. She both is and isn't how Sirius had imagined, looking far more like James's mother than his own as she immediately wraps her arms around her son.

It's a strangely intimate moment and Sirius averts his eyes only to find Kieren's sister staring daggers at him.

He falters only a moment before pasting on a wide, warm smile and giving slight bow. "Sirius Black," he tells her with complete honesty and as much charm as he can muster. "And you must me Jem. Your brother's told me a lot about you. All good things, of course. Overwhelmingly so."
