"De Patre Vostro (About Your Father)" is the series finale of the television series Rome. It is the tenth episode of the second season and 22nd overall. It originally aired on March 25, 2007.

After losing the Battle of Actium, a vanquished Mark Antony barricades himself with Cleopatra in their palace in Alexandria. The palace becomes a place of endless debauchery as Mark Antony and Cleopatra host orgies while drugging and drinking themselves into a stupor. Octavian sends an emissary to Mark Antony, with a secret message to Lucius Vorenus, offering him amnesty if he will betray Antony and open the palace gates in an attempt to avoid a direct assault on the palace which might lead to a popular uprising. It is made clear that Titus Pullo is aware that Caesarion is his son and that Vorenus also knows this. Mark Antony refuses Octavian's offer of unconditional surrender and challenges Octavian to single combat. Vorenus also refuses to betray Mark Antony. Meanwhile, Mark Antony's physical condition continues to deteriorate along with his mental condition. When he spars with Vorenus, he is easily defeated. When a bystander accidentally laughs, Antony is enraged. He then challenges the bystander, quickly killing him.

Octavian refuses the challenge as barbaric and secretly sends word to Cleopatra offering her the chance to keep the crown of Egypt and save the lives of her children if she gives up Mark Antony. She tricks Mark Antony into believing that she has committed suicide. Vorenus assists in Antony's suicide at his request. Vorenus, shocked to find Cleopatra still alive, tells her that Octavian will keep Mark Antony's children alive as a popular gesture of mercy but will almost certainly kill Caesarion as a potential rival to the rule of Rome; he also reveals his final orders from Mark Antony to escape with Caesarion to keep the boy alive. It is made clear that Cleopatra knows that Caesarion is actually Titus Pullo's son.
