Both of them, both of them saw themselves as natural heirs to Julius Caesar. Antony says, hey, this young little 18-year-old upstart, what has he done to deserve this empire? I've been beside Julius Caesar the entire time. Octavian's here saying, hey, I am now officially Julius Caesar's adopted son. He takes on the name Caesar. I am the rightful heir to Julius Caesar's power. And so sitting here in Tyre, Antony decides, okay, let me go take on Octavian.
