Intruders

Casey spies on the staff by installing a security camera in front of the nurse's station, and everyone begins ""performing for the spycamera."" Annie keeps trying to express her discomfort with the camera, but Casey keeps giving her the brush-off – so Annie jerks it off the wall. Meanwhile, Hank tries to locate Gina, but Julie's the only one who knows that she's returned to her native homeland. Jack passes himself off as a doctor to get into the doctors' lounge – but he ends up in surgery.
