Romeo · secret husband and wife · Juliet
They meet, marry and die within a few days. Juliet is often the more practical of the two, proposing marriage in the balcony scene, and in the end each dies rather than live without the other.
Romeo · close friends · Mercutio
Mercutio mocks Romeo's love and dies fighting the duel Romeo refuses. His death, under Romeo's arm, turns Romeo to revenge.
Romeo · cousins and friends · Benvolio
Benvolio, Montague's nephew, is Romeo's confidant and a would-be peacemaker: he urges Romeo to forget Rosaline, and after Tybalt's death to run.
Tybalt · enemies, then kinsmen by marriage · Romeo
Tybalt wants Romeo dead from the feast onwards. Romeo's refusal to fight him, because Tybalt is now his wife's cousin, is what drives Mercutio to fight in his place.
Friar Lawrence · confessor and penitent · Romeo
Romeo's “ghostly father” scolds him, marries him and talks him out of despair. His advice is often wise, though many readers find his plans rash.
Paris · rivals · Romeo
They meet only at the tomb, where Romeo kills Paris and then grants his dying wish to be laid beside Juliet.
The Nurse · nurse and confidante · Juliet
She has cared for Juliet since she was a baby and carries her messages to Romeo, but after Capulet's rage she advises her to marry Paris, and Juliet never confides in her again.
Lord Capulet · father and daughter · Juliet
In Act 1 he asks Paris to win her consent; in Act 3, Scene 5 he threatens to throw her out. His grief at her apparent death, and then her real one, shows the cost of his rage.
Lady Capulet · mother and daughter · Juliet
Formal and distant, she was a mother herself by Juliet's age and presses Paris on her daughter. When Juliet begs for her help against the marriage, she refuses to speak to her.
Friar Lawrence · confessor and helper · Juliet
He marries her, and when she threatens to kill herself he gives her the potion. In the tomb he leaves her alone when he hears the Watch coming.

Tybalt is Lady Capulet's nephew. At the feast Capulet forbids him to attack Romeo under his roof; Tybalt obeys, but promises that the intrusion will turn bitter.
Lord Capulet · heads of the feuding houses · Lord Montague
Neither ever explains the feud, which the Prince says was “bred of an airy word”. Over their children's bodies they take hands and promise golden statues.
Prince Escalus · kinsmen · Mercutio
Mercutio is the Prince's kinsman, so the feud costs the Prince his own family: by the end he has “lost a brace of kinsmen”, Mercutio and Paris.
