Trickery and Deceit

Last week Chad was looking for the key to the bathroom. He asked Justin if he knew where it was, Justin seemed to know that the key was gone, but said he didn't know where the key was. After Ashton got home from school that day she went to the bathroom and a bit later Chad found her in there yelling to get out. The door was locked with the key from the outside! Apparently, not only did Justin know where the key was, but he knew how to use it.
