In The Taming of the Shrew, why did Lucentio say the following quote in Act I, Scene 1?"Tranio, let's go. One thing more rests, that thyself...

Let us remember the context of this quote that you are
asking about. It comes towards the end of the first scene of this play, after Lucentio
and Tranio have overheard the conversation between Baptista and the suitors that want to
marry Bianca. They have devised a plan to win Bianca for Lucentio, and having planned to
swap places, now they must put their plan into action and allow the wooing to begin.
Lucentio has devised to pass himself of as a tutor, which he hopes will gain him access
to Bianca, and meanwhile, to cover for his absence, Tranio will play the role of his
master. Thus this quote neatly concludes their plan in Act I scene 1 and expresses
Lucentio's determination to make sure that he succeeds in wooing Bianca. Thus the plot
is set up and we shall see what happens during the accompanying
chaos.
