At the end of act 3, Hamlet accidently kills polonious. He is with his mother talking when he spots something moving behind the curtains. As it's his mother's bedroom he assumes that is Claudious and sees this as a chance to kill him as he'd already failed his first attempt. After realising it wasn't Claudious afterall and that it was in fact Polonious, Hamlet shows no remorse and thinks nothing of the fact that he had just committed cold blooded murder. A little bit later, the ghost turns up and Hamlet talks to the ghost; however, the mother cannot see nor hear anyone so thinks that her son is going mad.

In act 4 Hamlet goes and pulls Polonious' body apart. Hamlet is told that he's being sent away to England. Claudious seems to be relieved and feels like he has taken care of the risk of being exposed as a murderer and also of the risk of getting killed by Hamlet as revenge for his father.

Fortanbras arrives with his army seeking revenge on Norway.

Hamlet reads out he's soliloque in page 102 and 103 where he says 'my thoughts be bloody. He is really determined to at last avenge for his father and kill Claudious for all he has done, murdering his father as well as marrying his mother within 2 moths of his father's death; however, he has a porblem: he is being sent away to England.

In scene 5 Ophelia sings. The country want Laertes to be king. He returns to find out his father has been murdered and is after revenge. Ophelia has gone mad understandibly after all that she has been through. The king realises he needs to start thinking on his feet.
