In act 2, scene 3 of William Shakespeare's romantic tragedy Romeo and Juliet, Romeo goes to Friar Laurence early in the morning to tell him about Juliet, the new love in his life, and to ask the Friar to marry them as soon as possible. At first, Friar Laurence is confused about Romeo's visit, given the early hour and the jumble of thoughts pouring out of Romeo's mouth. The Friar thinks that Romeo has spent the night with Rosaline, a young woman with whom Romeo was utterly lovestruck and lovesick but who had no romantic interest in Romeo.
Once the question of Romeo's current love interest is resolved, the Friar takes Romeo to task for changing his mind about Rosaline so quickly, when just the day before, Romeo was weeping about his unrequited love for Rosaline.
"Thou chid'st me oft for loving Rosaline" (2.3.82), says Romeo, "And bad'st me bury love" (2.3.84). The Friar responds that he was merely chiding Romeo for doting on Rosaline. By telling Romeo to "bury love," he means for Romeo to forget about his infatuation with Rosaline but also not to jump so quickly from infatuation with one woman to infatuation with another, as he appears to have done.
FRIAR LAURENCE. Not in a grave
To lay one in, another out to have. (2.3.85–86)
The Friar makes an interesting if somewhat obscure reference to graves, which is the Friar's first foreshadowing of future events in the play regarding Romeo and Juliet's fate.
Later in the scene, Friar Laurence makes two more comments that more clearly and more directly foreshadow events in the play. In the first instance, although the Friar isn't convinced that he should marry Romeo and Juliet, he decides to do so for one particular reason: that "this alliance may so happy prove / To turn your households' rancour to pure love" (2.3.94–95). Friar Laurence believes that marrying Romeo and Juliet will put an end to the feud between the Capulets and the Montagues. Ultimately, it does end the feud, but not in the way that the Friar hoped it would.
In the second instance in this scene, Romeo urges the Friar to marry them as soon as possible. The Friar responds, "Wisely, and slow. They stumble that run fast" (2.3.97), but the Friar fails to take his own advice. It's the Friar's decision to marry Romeo and Juliet, and to do it as quickly as possible, that accelerates the action of the play which leads to Romeo and Juliet's deaths just two days later.
In act 2, scene 6, just before marrying Romeo and Juliet, Friar Laurence opens the scene in a positive way by saying, "So smile the heavens upon this holy act" (2.6.2). He then adds a not-so-positive remark that reflects his concern about the hasty marriage, "That after-hours with sorrow chide us not!" (2.6.2). This foreshadows the sorrow that does, indeed, "chide" not only Romeo and Juliet, but also everyone else in the play who is involved with them and their families.
Romeo tempts fate with his next speech. Overcome with his love for Juliet and caught up in the moment of their marriage, Romeo says that once they're married, he doesn't care what happens to them.
ROMEO. Do thou but close our hands with holy words,
Then love-devouring death do what he dare—
It is enough I may but call her mine.(2.6.6–8)
Friar Laurence responds, "These violent delights have violent ends / And in their triumph die" (2.6.9–10), meaning that the all-consuming love for each other that compels Romeo and Juliet to be married so quickly might just as quickly drive them to an equally "violent," all-consuming end.
Friar Laurence has a few more things to say that foreshadow coming events in the play. In act 3, scene 3, after Romeo kills Tybalt and runs away from the scene, Romeo seeks refuge with Friar Laurence. The first thing that Friar Laurence says to Romeo is that trouble seems to follow Romeo wherever he goes, which is definitely true.
FRIAR LAURENCE. Affliction is enamour’d of thy parts,
And thou art wedded to calamity. (3.3.2–3)
By "Thou art wedded to calamity," Friar Laurence isn't necessarily saying that Romeo's marriage to Juliet is a calamity, or that Juliet herself is a walking calamity, but that Romeo and misfortune seem to go though life hand in hand.
Friar Laurence then tells Romeo that Prince Escalus has banished him from Verona. Romeo falls to the floor "Blubbering and weeping, weeping and blubbering" (3.3.91) as the Nurse says, and then Romeo threatens to kill himself. The Friar scolds Romeo for even thinking about killing himself, and, in a sense, the Friar foreshadows events in the last scene of the play.
FRIAR LAURENCE. Hast thou slain Tybalt? Wilt thou slay thyself?
And slay thy lady that in thy life lives,
By doing damned hate upon thyself? (3.3.122–124)
Friar Laurence's final words on the matter foreshadow Romeo and Juliet's fate.
FRIAR LAURENCE. But, like a misbhav'd and sullen wench,
Thou pout'st upon thy fortune and thy love.
Take heed, take heed, for such die miserable. (3.3.149–151)
