Sirius wants to point out that he essentially already has a charm, that being his wand. But he's quite tired of arguing himself tonight and only nods instead. If it'll make Kieren feel better about the whole thing, he'll do it.

He frowns a bit at Kieren's added statement, feeling a mite defensive once again, but he bites his tongue as he helps Kieren to his feet.

Then, without a word, he turns to head back to their room, his shoulders a bit droopy and his muscles weary. The cold tea he'd brought up remains on the floor and he doesn't so much as bother to turn on the light once he's reached their bedroom, only quietly strips off his clothing, his back turned to Kieren so as not to give him the impression that he plans to try anything.
