Soldat looks between the charm and Owl Friend, then translates the question into Morse: "This will protect me?" Well, now it's not just going in their room, they're keeping it on their person. Maybe attached to their lantern.

Or maybe in a pocket. Somewhere it can't be damaged. They absolutely do not want to damage their friend's gift. (We're running out of room in our pockets. Make new ones? Hair. Asset, I don't know if it's a good idea to weave something long and glittery into our hair. Not actually sure I know how, anyway.)
