Revealing mistake: When Charlie is writing her letter we can see it through a hidden camera in the pen she is using. By watching the angle on how the camera would be attached to the pen we know that she would have seen the camera. Also her hand would be blocking the camera view, so we shouldn't be able to see anything at all. (00:30:30)
