The Fourth Prophicey

Remember the third prophicey said that Fleance(Banquo's son) was to be king. So Macbeth hires two guys to kill them. They track them down in a forest and Banquo is killed, but Fleance escapes. Macbeth is furious, when he finds out. Fleance was the one he really wanted dead.
Later at dinner he starts seeing things, he sees Banquo's ghost. Lady Mac, tries to clam him and eventually tells everyone to go home. People are starting to get suspicious.
Thi is where Macbeth hires people to kill Banquo and Fleance. " My genius is rebuk'd , as it is said Mark Antony's was by Caesar. He chid the sisters When first they put the name of the king upon me, and bade them speak to hom, then, prophet-like, They hail'd him father to a line of kings. Upon my head they plac'd a fruitless crown, And put a barren sceptre in my gripe." Macbeth.
