Horatio stays with Hamlet throughout the scene, joining him in making fun of Osric, offering to get him excused from the fencing match, and trying to join him in death. Horatio never really shows that he needs Hamlet. Horatio is the only one caring for him, taking care of him, making sure he is good, and okay. Active Themes All three men lament having lost the chance to communicate with the ghost. Horatio is the only friend/family Hamlet has. Horatio, like Fortinbras, is a man of actionand stands in stark contrast to the character of Hamlet, who struggles to take decisive action and ascertain what’s right. Apparently Hamlet has already told Horatio some of the story of his adventures on the sea between Denmark and England now Horatio hears the rest of the story. Horatio is one of the two people who know for certain that Hamlet’s madness is an act. These words of Hamlet's open the last scene of the play. "So much for this, sir: now shall you see the other / You do remember all the circumstance?" (5.2.1-2). In the last part of the scene, when Hamlet jumps into the grave to struggle with Laertes, Horatio says, Good my lord, be quiet" (5.1.265), but that's all. Horatio acts as the sounding board for some of Hamlet's flights of fancy about death. "Custom hath made it in him a property of easiness" (5.1.67), says Horatio, when Hamlet wonders at the fact that the gravedigger sings as he digs. This is the opening of the very short scene in which Horatio learns that Hamlet has returned to Denmark on a pirate ship. "What are they that would speak with me?" (4.6.1), Horatio asks a gentleman who tells him "sea-faring" men have letters for him. Also, Horatio apparently never tells Hamlet of Ophelia's madness. The "Gentleman" who is with him delivers the same message as he does.
These are Horatio's only lines in the scene, and we may wonder why he's there at all. "Twere good she were spoken with for she may strew / Dangerous conjectures in ill-breeding minds" (4.5.14-15), says Horatio to the Queen, of mad Ophelia. In the same scene, after the performance of The Murder of Gonzago, Horatio confirms to Hamlet that Claudius looked very guilty. We assume he does, but recall that the last time Horatio is present when Hamlet interacts with Ophelia is the 'mousetrap' scene, and Hamlet is not 'romantic' toward her.
Thus begins a passage of about thirty lines in which Hamlet expresses his admiration and friendship for Horatio. Best answer: IIRC, I dont think Horatio is shown to know about the Hamlet-Ophelia relationship in its full effect. "Horatio, thou art e'en as just a man / As e'er my conversation coped withal" (3.2.54-55). Horatio and Marcellus catch up with Hamlet after the Ghost has spoken to him. When the Ghost does appear and gestures for Hamlet to follow him, Horatio tries to keep Hamlet from going. He accompanies Hamlet to the walls of the castle to wait for the Ghost to appear again. "It is a nipping and an eager air" (1.4.2). Accompanied by Barnardo and Marcellus, he comes to tell Hamlet of the Ghost.
Horatio, a bit reluctantly, comes with Marcellus to hear about the Ghost. David Tennant as Hamlet and Peter De Jersey as Horatio
