He introduces a major conflict.
Step-by-step explanation:
William Shakespeare's tragedy play "Hamlet" revolves around the revenge act of Hamlet for the wrongful death of his father, King Hamlet. The young prince sets about exacting revenge on his Uncle/ stepfather and current king Claudius.
Act I scene ii of the play is when Queen Gertrude asks her new husband King Clausius to try to persuade her son Prince Hamlet to stay in Denmark. But more importantly than that, the ghost's appearance to the guards had led to the discovery of it being the dead king's ghost. In this second scene, Horatio finally decides to inform Hamlet about his late father's ghost and even decides to accompany them on guard the next time. This scene introduces the major conflict which will be the theme of the whole play.
