He listens, Thanatos's words sinking into his soul like water into parched land. This is what Thanatos does - this is part of who he is, and he wouldn't lie or mince words to make Ryo feel better. Ryo is absolutely certain of that.

So that means...

He did this. The soul has moved on - the soul is where they're supposed to be - because of him. This is what the change in his Sense is for. This is what his Diagad powers are for-

This is confirmation, played out right in front of him, by his hand, that his powers have changed. The power to kill with a touch is gone, if it had ever really been his to begin with; in its place is the power to help those who have already died, who would normally be out of his reach as a healer. He doesn't have to be afraid of himself anymore.

It's only when he feels a new, biting cold on his face that he realizes he's crying, the tears rolling down his cheeks rapidly cooled by the night air. He tries to wipe them away, only for them to be immediately replaced, and the dam bursts in a flood of abject relief, leaving him crying quietly into his hands, overwhelmed with emotion and unable to stop. "It's- it's okay," he manages, whispered words stolen between hitched breaths. "I'm okay."

It wouldn't make any sense to anyone else listening, but Thanatos should know enough to understand.
