The Soldier nods, hums the "I come in peace" phrase, then backs off a couple crouching steps before straightening up to follow Misty again, over to the chairs. They absolutely understand needing space and being gentle, and even having a rough time. "I can't use the instrument, so I'm trying to learn their language. By singing it. I learned how they refer to us."

A weird, automatic instinct has them pulling a chair out for Misty, then blinking at the chair like they're not sure why they did that. (Spoiler: they're not.)
