[Hans at least composes himself enough that he's not as defensive, keeping a more cool, if calm pitch of voice as he looks at the Arendelle queen.]

I don't plan on harming anyone, not right now. [He pulls his eyes away from her, just looking off into a different direction, mostly at the colorful decorations still hanging from the trees.] Believe it or not, I don't come into every situation planning to hurt others.
