Mercutio is one of Romeo's best friend but was also hinted to having a closer relationship to Romeo in the original script.
Mercutio likes to get wild and party, as seen when Mercutio got drunk after the party, " I conjure thee by Rosaline’s bright eyes,By her high forehead and her scarlet lip,By her fine foot, straight leg and quivering thighAnd the demesnes that there adjacent lie,That in thy likeness thou appear to us!
I conjure thee by Rosaline's bright eyes,
By her high forehead and her scarlet lip,"
But most well known for his Queen man speech, "MERCUTIO: O, then I see Queen Mab hath been with you.
She is the fairies' midwife, and she comes
In shape no bigger than an agate stone
On the forefinger of an alderman,
Drawn with a team of little atomies
Over men's noses as they lie asleep;
Her wagon spokes made of long spinners' legs,
The cover, of the wings of grasshoppers;
Her traces, of the smallest spider web;
Her collars, of the moonshine's wat'ry beams;
Her whip, of cricket's bone; the lash, of film;
Her wagoner, a small grey-coated gnat,
Not half so big as a round little worm
Pricked from the lazy finger of a maid;
Her chariot is an empty hazelnut,
Made by the joiner squirrel or old grub,
Time out o' mind the fairies' coachmakers.
And in this state she gallops night by night
Through lovers' brains, and then they dream of love;
O'er courtiers' knees, that dream on curtsies straight;
O'er lawyers' fingers, who straight dream on fees;"But he is very emotional and cares for what actions Romeo takes, "Mercutio. If love be rough with you, be rough with love; Prick love for pricking, and you beat love down. Give me a case to put my visage in: A visor for a visor! what care I What curious eye doth quote deformities? Here are the beetle brows shall blush for me."
