Original: Despite his success, Macbeth remains uneasy about the prophecy about Banquo, so Macbeth invites him to a royal banquet where he discovers that Banquo and his young son, Fleance, will be riding out that night.
Simplified: Act II starts with Banquo and his son Fleance walking in a courtyard in Macbeth's castle. They meet Macbeth, who lies to Banquo and says that he has not thought about the witches' prophecy.
