... Tokinaga became, or was already, infected and died. [he doesn't know if obikawa is the vengeful sort so he won't mention who killed him.] Likewise, Rafayel's health improved, but only in the sense that the infection properly awakened in him, and he killed his remaining companion.

He came to his senses afterwards, but the townspeople got a hold of him and likely killed him as well.

[there's the look of guilt again of someone wondering if he could've done something to prevent rafayel's death...]
