It is the Friars idea that Juliet administers a potion in order that she may appear dead until Romeo can return to Verona to rescue her.
Mercutio: The Princes kinsman and a close friend to Romeo. Mercutio is a colorful character who enjoys word-play and double entendres particularly of a sexual nature.

This prophecy is realized as the plot unfolds.
