[Byleth opened his eyes at the sound of her voice, and saw both the offered knife and her bleeding finger. He considered it for a moment, before carefully taking it and wiping the smudge of blood off with the gloved pad of his thumb.]

You should clean this knife after I use it. My blood can be toxic to other people if ingested or absorbed into wounds.

[With that, he started working his glove off to also carefully cut... the side of his index finger, rather than the pad of it. Less likely to be irritated by him touching things and easier to heal - and it won't bleed much either.

(He also made sure to wipe the knife clean on his trousers until not a smear of blood remained.)]

Who should go first? Or shall we do it at the same time?
