In this passage in act 5, scene 2, Tamora comes to Titus disguised as the personification of revenge. When he calls her Tamora, she says she is not Tamora, who is his enemy, but Revenge, his friend. She says she has come to "confer" with Titus and that people fear her. Titus questions whether she is truly Revenge and asks her to do a "service" for him. He wants her to kill her two sons, who have come with her in disguise. He calls them Rape and Murder. He says he will then be on her side.

Tamora poses as Revenge because she thinks Titus has gone insane and will be tricked by her disguise. However, he has only been pretending insanity. Tamora courts Titus because she wants him to invite Lucius to his house for a banquet in order to keep Lucius occupied while she causes chaos among his followers.

The poetic device of metaphor Tamora uses in referring to Titus's mind as a "gnawing vulture" enhances the sense that he is tortured by inner demons. Her description of revenge, as so powerful that

not a hollow cave or lurking-place,
No vast obscurity or misty vale

can give the guilty cover, shows that she understands Titus's desires and faith in revenge, and also amplifies the theme that revenge is a powerful and frightening force.

When Titus asks for proof that she is Revenge, he says:

Stab them [her sons], or tear them on thy chariot wheels,
And then I’ll come and be thy wagoner,
And whirl along with thee about the globe.

The graphic imagery of wanting her to "stab" or "tear" her sons on her chariot wheels enhances the idea that Titus is fixated on violent, bloody revenge. It also foreshadows what he will do to the sons, which will be to kill them. The alliteration in the w in "wheels," "wagoner," and "whirl" emphasizes the way revenge is a force always in motion.
