Fluter dies, leaving Cleopatra VII, now 18, as joint ruler with her young brother Ptolemy XIII. Cleopatra makes it clear her brother's regents can 'advise' him, but not her. Cleopatra, deceived by her brother's adviser Pothinus, receives and charms Pompey's son Gnaus, who has come to seek Egyptian support in for his father in his civil war against Caesar. This enrages the mob and Cleopatra has to flee, as Pothinus planned. The defeated Pompey is allowed to land by Ptolemy and his advisers; they then kill him, expecting to win the pursuing Caesar's approval. This does not work, Caesar is affronted by their treachery.
