"He is a nobleman and tribune who acts first as a messenger for Saturninus and then as a supporter of Lucius in the play's final scene. In IV.iv, Aemilius reports to the emperor that the Goths, under the leadership of Lucius, are marching on Rome. Saturninus asks him to take a message to Lucius proposing a peaceful meeting at Titus's house. He does so in V.i. Aemilius arrives for the feast at Titus's house in the company of Saturninus and Tamora, but at the close of the play, with Saturninus dead, he proposes that Lucius be the next emperor, noting that Lucius appears to be the choice of Rome's citizens" (e-notes).

Another view of Roman tradition, not necessarily Ameilius, is family loyalty. An attack on any member of the family is viewed as an attack on the entire family and must be dealt with through group solidarity of action.
