I demand you, Gertrude, to avoid Claudius's bed!!
Son, stop it!!
Claudius I'm coming for you! It is about time that I kill you!!
I'm not Claudius...
Scene 4: Hamlet is very specific in this scene and tells her not to let Claudius arouse her by fondling her neck, and other shockingly graphic details.
Scebe 4: Hamlet, realizing that someone is behind the arras and suspecting that it might be Claudius, cries, " How now! A rat?" (line 22). Hamlet then draws his sword and stabs it through the tapestry, killing the unseen Polonius.
