Final answer:
After Ophelia is placed in the grave, Laertes leaps into the grave in grief, which leads to a confrontation with Hamlet.
Step-by-step explanation:
The student has asked what Laertes does after Ophelia's body is placed in the grave. In William Shakespeare's tragedy Hamlet, once Ophelia is placed in the grave, Laertes leaps into her grave in a dramatic display of his sorrow and love for his sister.
Laertes's action is a catalyst for further confrontation when Hamlet, upset by this scene and mourning Ophelia in his own way, also jumps into the grave, leading to a heated argument and a physical altercation between Hamlet and Laertes, both of them grappling with their grief and each other in Ophelia's grave.
After Ophelia's body is placed in the grave, Laertes takes action. In Shakespeare's play Hamlet, Laertes is grief-stricken and angered by his sister's death. He jumps into the grave, demands to be buried with her, and then engages in a physical altercation with Hamlet, who is also mourning Ophelia.
