Act 3, Scene 4

    After Banquo is murdered, Macbeth continues on with his glories of being king, but we discover his guilt is beginning to rise. Macbeth and Lady Macbeth enter the room with their court to see the feast that is served for them. One of the murderers arrive and tell Macbeth that Banquo is dead, but Fleance escaped. When Macbeth returns to the table he goes to sit in his seat at the table, but notices to his own eye of guilt rising that Banquo's ghost is sitting there. When Macbeth makes a big scene, Lady Macbeth is forced to be the calm one, which is surprising because she is psycho, and excuse herself and Macbeth from the table.

    As Macbeth and Lady Macbeth are talking about Banquo's ghost, Macbeth talks about the river of blood that he is in. He is in so deep and had killed so many people that if he would turn around in the river and go back it would be the same as him just finishing what he started and continuing to walk all the way to the other side of the river.
