The intruder wasn't done. He disappeared for a moment as he went into the walk in closet, only to return with belts in hand. Amanda struggles as he takes a hold of her legs and binds them to the bed posts, forcing her onto her back.  From Chuck's camera angle, he can see between Amanda's legs pretty good, and since his house is slightly elevated to the Carston's, he can partially see her chest and face. The girl looks even more terrified than she did before, if that was possible.
