Not mute; Samus just didn't see the point in wasting words, especially when the boy seemed so fond of them himself. So she held up a finger, wishing there was something shinier or sparkly on it to hold his attention better, and then waved her hand as she turned in the universal gesture for follow me, and started toward the counter.

Once there, she pulled out a file box that Apu had pointed out to her, marked with a label that read Employee Files, which had been decorated with little hearts and a fine layer of dust. She brushed it off, glad for her helmet to keep her from coughing (because even her tolerance for different atmospheres would have been put to the test with that dustcloud), and opened it up. She then turned it toward the boy, shoved it toward him, and nodded at it, wondering if he'd be able to pick up that she wanted to see which file was his so she could have more than just Mr. Hank to go off of.
