Sirius still wants to insist that he's doing no such thing, that his worries are completely reasonable given the events of the evening. And it wasn't so long ago that some people wanted Kieren dead simply for his affliction, of which he had no control. How is he being unreasonable for simply wanting to keep Kieren safe?

But it's obvious Kieren is worn out, both from the encounter with the beast as well as the argument, and Sirius forcibly swallows back the words. It takes quite a bit of effort.

"A charm," he says, because he's not giving up on that. He pushes himself to his feet and holds his hand out for Kieren to help him up. "It won't be anything that draws attention, I'll make sure of it. Can we at least go to bed together or am I being relegated to the sofa tonight?"
