It's clear that Sirius doesn't understand the magnitude of what he's said – doesn't really get what he's trying to say at all. If he does, he's doing an admirable job of hiding it. Perhaps it's for the best, though. If Sirius doesn't fully grasp what he'd been trying to say. It's not like it would make a difference, anyway. Nothing would change.

He watches Sirius closely for a moment, scrutinizing his expression for any hint of... he doesn't know what. Finally, he nods. With one last squeeze to the fabric between his fingers – not even something Sirius would be able to feel – he releases his grasp on Sirius' sleeve.

It feels like letting go of something forever.

"You'll be all right?"
