In Act IV of Julius Caesar, Antony/Octavious have more power than the others. As this act opens, Rome is under the control of the triumvirate of Antony, Octavius Cesar, and M. Aemilius Lepidus. And, the triumvirs decide who are their political enemies, and whom they will keep as allies. However, Antony speaks to Lepidus, telling him to go to Caesar's house and retrieve the will so that they can make changes in it. When he departs, Antony, who plans to use Lepidus, tells Octavius that Lepidus is expendable:
This is a slight unmeritable man.
Meet to be sent on errands; is it fit,
The threefold world divided, he should stand
One of the three to share it? (4.1.13-16)
But, Octavius, the adopted son of Julius Caesar, defends Lepidus. saying he is "a tried and valiant soldier"(4.1.30-31). Here Octavius demonstrates that he is the adopted nephew of Caesar, and will not be influenced by Antony.
