echos

The echos when R or G talk could be that since they are not being used in the play they don't directly affect anything. The echos comes from their voices but when it is heard people look around where the two stand but never seem to take notice in them. They pass off the echo as a voice they made up in their head. Because the two charcters arent being used as Claudius' tools they do not effect the story because they have no part other than when they are needed. The play never said anyhtign to the effect of what they do off stage.
