In act 3 scene 2 Hamlet stages a play, which he calls ';The Mousetrap'; which re-enacts the murder that Claudius committed. Claudius interrupts the performance and yells ';Give me some light:away!'; The next time we see Claudius, he is on his knees attempting to pray, although he later admits that his thoughts did not go up to heaven.At what point in Hamlet did Claudius figure out that Hamlet knew he killed his father?
There is no specific point, but I think sometime during the ';play within the play'; scene: Claudius probably saw through what Macbeth was trying to do.





%26amp; Also, he definitely was onto Hamlet after Hamlet stabbed Polonius (hiding behind the curtain), because Hamlet thought Polonius was Claudius. As Claudius said, Hamlet was a threat to him and his wife, etc. %26amp; so he wanted Hamlet shipped off to England for the King's safety.

Most believe that it was during the play within a play scene ';Mousetrap';
