Hamlet- Act 4 Scene 5

The scene opens with Gertrude, Gentlemen, and Horatio discussing Ophelia's behavior. Gertrude wishes to not speak with Ophelia, but complies. The audience gets an insight into Ophelia's madness as she enters singing odd songs and acting rather strange. I can understand Ophelia's lack of sanity due to her father's death, the removal of Hamlet, and the rumors stirring about her father's death. She implies to Claudius that she hopes he gets what he deserves in lines 42-44, "They say the owl was a baker's daughter. Lord, we know what we are, but know not what we may be. God be at your table." So, I think Ophelia believes Claudius to be the reason for her father's death. Also, she is still very hurt from Hamlet's absence, that she sings songs that explain her innermost emotions. Most of the songs refer to sex and the uncertainty of true love.
Ophelia is not the only one deeply affected by her father's death, but also her brother, Laertes. He returns in secrecy from France with with a rebellious mindset to take control over the kingdom and avenge his father's death. This seemed all too familiar because now we not only have Hamlet and Fortinbras avenging deaths, but a third as well! The citizens are on board with Laertes becoming king. Claudius pleads his innocence, but then Ophelia reenters with a lack of sanity, and Laertes's rage comes back. Both Claudius and Laertes come to a conclusion to send Laertes's friends to hear out King Claudius and decide if he is guilty or not. If he is guilty, Claudius agreed to give up his crown to Laertes, but if decided he is innocent, the proper person who killed Polonius will be put to death. Since Claudius wants Hamlet dead, will he tell everyone that Hamlet is the murderer? Secondly, Ophelia has too much going on in her life and no one to turn to, I wonder how soon she will kill herself.
