   As soon as you exit the cage at the very
 beginning, look left and up to see Richard
 Vander Wendee's child in the lower right-hand
 corner of the screen. Also if you go over to

 see the faces of Robyn Miller's two children
 in the upper-left corner. The guard's body
 must have been removed first.
