Zoro stubbornly swallows a primal grow that threatens to burst from his chest. Pinned under some strange kid's Concerned Gaze, his body screams "danger!" and his blood itches to tear this person's throat out.

But instead of reaching for his blades, he grounds out between clenched teeth: "I don't know what the hell you're talking about."

(It's probably the almond-shaped feline eyes. Or the pair of fangs he's angrily baring at the young man in front of him. But that would mean admitting his body is changing without his say so...and Zoro's frayed nerves aren't leaving much room for thoughts outside of "fight" or "die".)
