The Soldier doesn't look up, hearing the feet so not surprised, then hearing the voice and knowing who it is. It makes sure to make a few gears in its arm spin a little louder, so Matt knows who it is, too, before speaking. "It's spare fabric," it explains. "Could be. Something better. I just don't know to make it something better." The feeling that it should know is frustrating, and standing here for a couple hours probably isn't going to help it figure out what it doesn't know.
