Sir Toby Belch is introduced, he is Olivia's uncle
Sir Toby Belch complains to Maria about his nieces behaviour
Maria advises Sir Toby to keep his drinking and revelry under control
Maria and Sir Toby gossip about Sir Andrew who is trying to woo Olivia
When Andrew arrives, his vanity and literal-mindedness are made the butt of the others' bawdiness and quick wits
Sir Toby needs Sir Andrew's money and so encourages him in his love for Olivia and the idea that he is an excellent dancer
Sir Andrew capers to Sir Toby's command as he is gulliable
Sir Toby is characterised by excess and refuses Maria's remarks about self-restraint as he is devoted to self-gratification without much thought for others
Scene 3 is in prose rather than blank verse and the word play is of a bawdy and bantering style
