An example of fate is Juliet getting the chance to have the vial from the Friar in act 4 scene 1, "Take this thou vial, being then in bed, and this distilled liquor drink thou off; when presently through all my veins shall run a cold and drowsy humor, for no pulse."
In act 4 scene 1, a character trait for Paris is considerate, "Immoderately she weeps for Tybalt's death, and therefore have I little talked of love." He knows that Juliet needs time to grieve so he is considerate of that.
In act 4 scene 3, Juliet experiences free will because she has to decide if she wants to take the vial or not, "Come, vial. What if this mixture do not work at all? Shall I be married tomorrow morning? No, no! The shall forbid it, Lie thou there." This is an example of free will because she has to decide if she wants to take the vial or not.
A character trait for Juliet is bavery. In act 4 scene 3, she decides to take the vial. She didn't know if the vial was going to work, or if it is going to kill her but she took it anyway, "Seeking out Romeo, they did spit his body. Upon a rapier's point. Stay, Tybalt, stay! Romeo, Romeo, Romeo, I drink to thee!"
A character trait for Friar Lawerence in Act 4 scene 1 is trustworthy, "O Juliet, I already know thy grief; It strains me past the compass of my wits. I hear thou must, and nothing may prorogue it, on thursday next be married to this County." This shows he is trustworthy because Juliet and everyone else can come to him with anything and he keeps it to himself.
