In another part of the forest, Audrey admits to Touchstone that another man is in love with her.
Just then, the other man wanders in and Touchstone chats with him about his background.
Touchstone sweetly suggests, in both language of the forest and the court, that William get lost or Touchstone will kill him. Here's a little sample: "I will kill/ thee a hundred and fifty ways. Therefore, tremble, and depart."
William is off, with a hearty "God rest you merry, sir."
With that potential plot-disruption out of the way, Corin is free to enter and announce to Touchstone that Ganymede and Aliena want him immediately. As in, now.
