"Myrcella's a sweet, innocent girl and I don't blame her at all for you."

- Tyrion Lannister insulting Cersei Lannister, mother of Myrcella Baratheon

Myrcella Baratheon is a recurring character in the first and second season. She is played by guest star Aimee Richardson and debuts in the series premiere. Princess Myrcella is commonly thought to be the only daughter of King Robert Baratheon and Queen Cersei Lannister. Her real father is Jaime Lannister. Her older brother Joffrey Baratheon is the current King on the Iron Throne. She has been sent to Dorne as part of a marriage pact with House Martell.

Background
Princess Myrcella is commonly thought to be the only daughter of King Robert Baratheon and Queen Cersei Lannister. Cersei and Robert made a political marriage alliance after Robert took the throne by force from the Mad King Aerys II Targaryen. Myrcella has an older brother, Joffrey, and a younger, Tommen. The real father of all three children is Jaime Lannister. She often attends tournaments with King Robert. She has a sweet and quiet disposition and is fond of her Uncle Tyrion Lannister.

Season 1
Myrcella accompanies her family north to Winterfell after the death of Jon Arryn. During their stay Bran Stark is severely injured. Myrcella is eating breakfast with Cersei, Jaime and Tommen when her uncle Tyrion joins them. Myrcella asks whether Bran will die and Tyrion replies that he is expected to live, delighting Myrcella and horrifying Cersei. Tyrion excites Myrcella and Tommen by announcing that he wishes to see the Wall and the “wintry abode of the White Walkers.” He then amuses them by claiming that he wants to urinate off the edge of the wall. Cersei is irritated by his rudeness and leaves, taking the children with her.

Myrcella attends the tournament to celebrate Eddard Stark becoming Hand of the King. She witnesses the horrific death of Ser Hugh of the Vale during his joust against Ser Gregor Clegane. Myrcella returns for the second day of the tournament and applauds when Ser Loras Tyrell unseats Gregor. Gregor attacks Loras and Sandor Clegane intervenes. King Robert calls an end to the fighting. Myrcella joins the applause when Loras declares Sandor a champion.

Season 2
Myrcella attends Joffrey's Name Day Tourney. She is pleased when her uncle Tyrion Lannister arrives during the festivities and tells her that she is beautiful. She tells Tyrion that she is glad that rumors of his death were not true.

Myrcella attends a tense dinner with her younger brother Tommen, her mother Cersei, and Sansa Stark. Myrcella naively makes smalltalk with Sansa, asking when she will marry Joffrey, Cersei explains it will be after the war ends. Myrcella says that she is excited for the new gowns she will wear to the wedding. She good-naturedly points out that Sansa will be wearing an ivory gown as the bride. Sansa isn't sure how to react but Cersei presses her to respond. Sansa parrots the usual lines that she looks forward to being married to Joffrey.

In order to strengthen House Lannister's political position during the War of the Five Kings, Hand of the King Tyrion Lannister makes plans to forge a marriage-alliance with House Martell of Dorne by having Princess Myrcella wed to Trystane Martell, the youngest child of the current ruler of Dorne. In return House Martell would hopefully supply soldiers to the Lannisters' side, or at least ensure they wouldn't openly side with their enemies. The actual marriage ceremony will wait until Myrcella is old enough, but part of the arrangement involves sending her to Dorne to live in Trystane's household. Queen Cersei is furious with Tyrion when she hears (from Grand Maester Pycelle) what he is planning, declaring that she won't let her only daughter be shipped off to Dorne as she was shipped off to Robert Baratheon. Tyrion counters that as a princess, many would say that Myrcella was born to one day forge a marriage alliance, and she will be safer in Dorne than in the capital city during a major civil war. Against Cersei's continued protests, Tyrion insists that the plan has already been finalized, leaving Cersei fuming and in tears for her daughter.

Myrcella later plays with her handmaidens in a castle garden before the eyes of Septa Eglantine, while her inebriated mother bitterly criticizes Tyrion for being ready to "seal my daughter in a crate so you can ship her away". Tyrion insists that she will be safer in Dorne, and Cersei mocks his concern for her. Tyrion firmly says that he is indeed concerned for Myrcella's safety: she is a sweet, innocent girl, and "I don't blame her at all for you".

Myrcella departs King's Landing on a ship bound for Dorne, crying as she is sent away, accompanied by a knight of the Kingsguard and is seen off at the docks by a formal royal procession including King Joffrey, Prince Tommen, Queen Cersei, and Sansa Stark.

In the books
In the Song of Ice and Fire novels Myrcella is a quiet, obedient and honest girl, eight years old when the events of the books begin. Myrcella is a year younger than Arya Stark, and a year older than Bran Stark. She is said to have inherited her mother's looks, but none of her personality. Her mother dotes on her and is keen that she does not suffer Cersei's fate of being "sold" in a political marriage without love.

According to the TV series official pronunciation guide developed for the cast and crew, "Myrcella" is pronounced "Mer-SELL-uh", as opposed to "MER-sull-uh" (that is, it doesn't rhyme with "Ursula").
