How does Rosalind play an important role in the scenes of Act 3?

One of the characteristics of Rosalind is that she is dealing with a play that is primarily created for her pleasure. She therefore becomes the director of the play, managing all of its subplots and influencing the action. She says, "Bring us to this site, and you shall say / I'll prove a busy actor in their play" (3.4.52-53). In this sense Rosalind is like Puck in A Midsummer Night's Dream. She can intervene in others' lives and play games with them. However, at the same time that she is controlling others, Rosalind is still unliberated from Celia. By being a part of the play and directing the actions of the other characters, Rosalind will achieve a liberation from Celia that will allow her to marry Orlando.
