What happens when hamlet comes out of hiding during ophelia's funeral?

He and Horatio hide as the procession approaches the grave. As Ophelia is laid in the earth, Hamlet realizes it is she who has died. At the same moment, Laertes becomes infuriated with the priest, who says that to give Ophelia a proper Christian burial would profane the dead. ... Hamlet storms off, and Horatio follows.
