Context paragraphs:
Characters in Romeo and Juliet: Prince Escalus, the Prince of Verona, is the desperate resolver of the feuding families.  He is based on the actual Scaligeri family which ruled Verona, possibly on Bartolomeo I.  Escalus is the voice of authority in Verona.  He appears only three times within the text and only to administer justice following major events in the feud between the Capulet and Montague families.  He first punishes Capulet and Montague for the quarrel between Tybalt, Benvolio, and a handful of servants.  He returns too late to stop the fatal brawls between Tybalt and Mercutio and, subsequently, Tybalt and Romeo.  Escalus is prepared to execute Romeo for his offence—Romeo's killing Tybalt—but lightens the sentence to lifetime banishment from Verona, when Benvolio insists that Tybalt started the quarrel by murdering Mercutio, a kinsman to the Prince.  He yells at Lord Montague for engaging in the feud, which really is the root cause which led to Tybalt killing Mercutio.  So, according to him, he lost his dear kinsman because of Lord Montague, so by exiling Romeo, Escalus gives him a 'taste of Montague's own medicine', to see how Montague feels when he loses a loved one.  Prince Escalus returns in the final scene—V.iii—following the double suicide of Romeo and Juliet, and at last declares the Lords Montague and Capulet guilty of Romeo and Juliet's death, and angrily tells them that their totally useless feud resulted in the deaths of not only their own loved ones (Lady Montague, Romeo, Juliet, and Tybalt), but also in the deaths of Escalus' loved ones (Mercutio and Paris).  He curses the feud that kills Romeo and Juliet whom he really feels sad for, just before the Lords come to peace with each other.  In the end, Prince Escalus becomes very happy that the feud has finally ended, even if with a heavy price, since it ended late.

Mercutio: Mercutio ( ) is a fictional character in William Shakespeare's 1597 tragedy, "Romeo and Juliet".  He is a close friend to Romeo and a blood relative to Prince Escalus and Count Paris.  As such, being neither a Montague nor a Capulet, Mercutio is one of the few in Verona with the ability to mingle around those of both houses.  The invitation to Capulet's party states that he has a brother named Valentine.

Romeo × Juliet: Romeo × Juliet (ロミオ×ジュリエット , Romio to Jurietto ) is an anime television series, loosely based on William Shakespeare's classical play, "Romeo and Juliet", along with numerous references and characters from other Shakespearean plays.  Though the anime borrows mostly from Shakespeare's story, the manga adaptation differs extensively from the original.  "Romeo × Juliet" was broadcast in Japan on Chubu-Nippon, broadcasting from April 4, 2007 to September 26, 2007.  In 2009, "Romeo × Juliet" was dubbed into English and released by Funimation Entertainment.

Tybalt: Tybalt is the main antagonist in William Shakespeare's play "Romeo and Juliet".  He is the son of Lady Capulet's brother, Juliet's short-tempered first cousin, and Romeo's rival.  Tybalt shares the same name as the character Tibert/Tybalt the "Prince of Cats" in "Reynard the Fox", a point of mockery in the play.  Mercutio repeatedly calls Tybalt "Prince of Cats" (perhaps referring not only to Reynard but to the Italian word cazzo as well).  Luigi da Porto adapted the story as "Giulietta e Romeo" and included it in his "Historia novellamente ritrovata di due Nobili Amanti" published in 1530.  Da Porto drew on "Pyramus and Thisbe" and Giovanni Boccaccio's "Decameron".  He gave it much of its modern form, including the lovers' names, the rival families of Montecchi and Capuleti, and the location in Verona.  He also introduces characters corresponding to Shakespeare's Mercutio, Tybalt, and Paris.  Da Porto presents his tale as historically true and claims it took place in the days of Bartolomeo II della Scala (a century earlier than Salernitano).  Montague and Capulet were actual 13th-century political factions, but the only connection between them is a mention in Dante's" Purgatorio" as an example of civil dissension.

Rosaline: Rosaline ( or ) is an unseen character and niece of Capulet in William Shakespeare's tragedy "Romeo and Juliet" (1597).  Although silent, her role is important.  Romeo is at first deeply in love with Rosaline and expresses his dismay at her not loving him back.  Romeo first spots Juliet while trying to catch a glimpse of Rosaline at a gathering hosted by the Capulet family.

Count Paris: Count Paris or County Paris is a fictional character in William Shakespeare's "Romeo and Juliet".  He is a suitor of Juliet.  He is handsome, wealthy, and a kinsman to Prince Escalus.

Queen Mab: Queen Mab (pronunciation: "M/ă/v") is a fairy referred to in William Shakespeare's play "Romeo and Juliet", where "she is the fairies' midwife."  Later, she appears in other poetry and literature, and in various guises in drama and cinema.  In the play, her activity is described in a famous speech by Mercutio written originally in prose and often adapted into iambic pentameter, in which she is described as a miniature creature who performs midnight pranks upon sleepers.  Being driven by a team of atomies, she rides her chariot over their noses and "delivers the fancies of sleeping men."  Additionally, while driving "O'er ladies' lips, who straight on kisses dream," she was known to change her mind and instead "plague" "ladies' lips" "with blisters" if she smelled "sweetmeats" or candied fruit eaten to sweeten their breath.  Along with this interpretation, others believe the blisters were a reference to the plague or to herpes simplex.  She is also described as a midwife to help sleepers 'give birth' to their dreams.  She may be a figure borrowed from folklore, and though she is often associated with the Irish Medb in popular culture, and has been suggested by historian Thomas Keightley to be from "Habundia", a more likely origin for her name would be from Mabel and the Middle English derivative "Mabily" (as used by Chaucer) all from the Latin "amabilis" ("lovable").

Mab (moon): Mab ( ), or Uranus XXVI (26), is an inner satellite of Uranus.  It was discovered by Mark R. Showalter and Jack J. Lissauer in 2003 using the Hubble Space Telescope.  It was named after Queen Mab, a fairy queen from English folklore who is mentioned in William Shakespeare's play "Romeo and Juliet".

Romeo + Juliet: William Shakespeare's Romeo + Juliet (shortened to Romeo + Juliet) is a 1996 American romantic drama film directed, co-produced, and co-written by Baz Luhrmann, co-produced by Gabriella Martinelli, and co-written by Craig Pearce, being an adaptation and modernization of William Shakespeare's tragedy "Romeo and Juliet".  The film stars Leonardo DiCaprio and Claire Danes in the leading roles of Romeo and Juliet, who instantly fall in love when Romeo crashes a party and meets her, despite their being members of the Montague and Capulet family; Brian Dennehy, John Leguizamo, Pete Postlethwaite, Paul Sorvino, and Diane Venora star in supporting roles.

A rose by any other name would smell as sweet: "A rose by any other name would smell as sweet" is a popular reference to William Shakespeare's play "Romeo and Juliet", in which Juliet seems to argue that it does not matter that Romeo is from her rival's house of Montague, that is, that he is named "Montague."  The reference is often used to imply that the names of things do not affect what they really are.  This formulation is, however, a paraphrase of Shakespeare's actual language, seen underlined below.  This scene is called the balcony scene by many people.  Juliet not only makes the statement above but compares Romeo to a rose saying that if he wasn't named Romeo he would still be handsome and be Juliet's Love.  Also as said before this states that if he wasn't Romeo, then he wouldn't be a Montague and she would be able to get married with no problem at all.
