There's Scarlett's room, but that seems kind of rude, and besides, it thinks she's probably in there. "I stay in the village. I don't really care about needing privacy, unless you do." He's going to talk to the Soldier's metal arm. How much privacy does that need? It's not likely that anyone else if going to understand, right?

It does have tools, though, just a small packet in one of its many pockets (one accessible with the flesh hand, because that's just common sense), made especially for dealing with the arm. Just in case it fishes those out.
