Willhelm quickly darts out of the room and  flattens his back against the wall next to the room. Wait antique? He wanted to yell out in anger but he realizes that this is the middle of the wasteland and angering the wrong people is not a good idea. Instead he continues to keep his hand on his katana. Then says in a neutral but stern voice. "Hello , I do not mean any harm. I am a traveler and only came here to rest. " He kept his hand on his katana and waited for a response. He saw a rifle so if this becomes a fight it wont be a easy one if he can not get close.
