Strange…The way he's phrasing it makes it sound almost like a request. Mikleo tilts his head slightly to one side, trying to comprehend the words, a puzzle left in scattered corners of his clouded mind. Is the exorcist's command that he walk at his side, rather than rest within? Is he expected to be combat-ready at all times?

It's confusing, trying to interpret the words without orders. After several moments of strangled thought he manages, “Malakhim don't require sleep. Command me to walk with you, and I will.”
