Even expecting it as he is, Kieren's cries send a chill straight down Sirius's spine. To be honest, he'd would be quite happy to never hear again hear Kieren in so much pain, to never again be the direct cause of such pain, even if it is for an eventual good.

As it is, there's nothing to be done for it apart from squeeze Kieren's shoulder as tightly as possible, a reminder that he's right there, that the pain will stop in due time.

And, eventually, it does, the tension bleeding from Kieren's muscles bit by bit, his brow tinged with sweat and eyes cloudy with unshed tears when he meets Sirius's own once more.

"Can you move it?" he asks, nodding down at Kieren's wrist, still a bit worried he's messed up some despite his earlier confidence.
