Hamlet 2:1

Question 1:
The first half of the scene is just Polonius paying Reynaldo to spy on his son Larates. Then Ophelia comes in to tell Polonius that she's really scared because Hamlet came into her room acting and looking crazy. He tells her that he is going to go tell the king then asks if he acted that way because they argued. She said no, it was because you made us break up. Then he says that he wished that he hadn't and the scene ends.
Question 2:
The most important line is when Polonius says "But beshrew my jealousy," after Ophelia told him that Hamlet was acting weird. Its important because it shows that Polonius has a heart and regrets being mean to his daughter.
Question 4:
My favorite line is when Ophelia says "No, my good lord, but as you did command I did repel his letters and denied his access to me," when talking about why Hamlet was acting strange. I like it because it explains that Ophelia didn't want to break up with Hamlet.
