Back in Athens at Antony’s house, Antony complains to Octavia of Caesar’s behavior since their departure. Caesar has broken their pact and waged war against Pompey, not to mention he has railed against Antony in public.
Octavia laments that she’s monkey in the middle of this mess, and she pleads with him not to believe the reports against her brother. She wouldn’t know whom to support in a quarrel between her brother and her husband.
Antony tells her not to fear; he’ll win back his honor by raising a war against Caesar.
He sends his wife back to Rome to be with her brother (and ostensibly make peace between them) while he prepares for war with Caesar.
