Consider the scene where Laertes confronts King Claudius. What differences do you notice between Laertes’s interactions with the King and Hamlet’s? In what way is Laertes a foil for Hamlet? (A foil is a character who contrasts with the protagonist.) Use textual evidence.
Please note: The post contains several elements. The eNotes Homework Help policy allows for one question per post. This answer addresses the last question.
Laertes is a foil to Hamlet in several ways. There are some important similarities between these two characters. They are both young men who have spent time away from court, and both lose their fathers. In Hamlet's case, the death of King Hamlet occurred before the play's action started. For Laertes, however, his father's death is a pivotal event in the play. Whereas Hamlet had been the more serious youth, Laertes now turns away from his frivolous behavior.
Because Hamlet kills Polonius, Laertes is obligated to avenge his death. This responsibility both establishes another similarity between them, as Hamlet is also seeking revenge on his father's killer, and makes them enemies. Another parallel is that they both have Ophelia's best interests at heart. But here, too, they diverge. Hamlet speaks harshly to Ophelia, trying to get her to leave the dangerous court. After she dies, Laertes blames Hamlet for her death, which adds another family member who must be avenged.
Ultimately, they are so close that they die together, with Laertes first understanding his errors about Hamlet and Claudius. In dying they come even closer, as both are killed by the poison-tipped sword, which represents Claudius's treachery, not in a fair duel as would befit their honorable natures.
