Gaius to Uther

Beauty and the Beast is the fifth and sixth episode of the second series of Merlin which was first broadcast on the 31st October, 2009. It marks the show's first ever two-parter.


Part OneEdit

Uther is captivated by his latest guest, the beautiful Lady Catrina. Arthur is appalled by his father's flirting, but Merlin is wary for a different reason - he suspects she is really a troll!

Catrina and her strange servant are welcomed into the heart of Camelot, and it is up to Merlin to prove she is a monster and save Uther from ruin. Unfortunately, Catrina has her sights set on a far greater prize than the king's heart - can Merlin overcome her powerful troll magic before it is too late?

Part TwoEdit

Newly crowned Queen Catrina settles in as Camelot's first lady. As her true troll nature surfaces, her influence over Uther increases, and the repercussions are felt throughout the kingdom.

When Catrina accuses Merlin of stealing, he is forced into hiding. Forced to sneak around the castle, Merlin must find a way to expose Catrina's true form without getting caught and beheaded. Even if he succeeds, is it enough to break her powerful magic? Or will Camelot be stuck with a troll queen forever?

Plot Edit

Part OneEdit

Part TwoEdit

After the royal wedding, Catrina, the new queen of Camelot tells Uther that her father's seal has been stolen by Merlin. Arthur sends his men to find the seal, while he rushes to his chambers to warn Merlin, telling him to leave Camelot or else he will die. Merlin leaves as Arthur tells his father that Merlin has escaped his men and could be out of Camelot.

Uther is clearly attracted to Catrina

Underground, Catrina tells Jonas her plan of getting Arthur undermined by his father. In the forest, a few bits of Merlin's clothing is found and returned to Camelot with news that Merlin is headed for the northern border. Gwen worries for Merlin's life while Gaius reassures her he can outrun them, before returning to the northern borders. Merlin, who had been hiding in a barrel in Gaius' chambers, leaves to follow Catrina.

While spying on her, Merlin sees Catrina taking the potion which makes her troll body into a human body. In the throne room, Uther, still being under the spell of Catrina, tells Arthur he is ordering a new tax on the people of Camelot even though Arthur says they cannot possibly pay the king's taxes. Catrina says that Uther had been thinking about such a tax for quite awhile when Arthur mentions the sudden change in his father's attitude to the treatment of the citizens of Camelot.


The Troll

Merlin sneaks into Jonas' room while he's asleep and steals the potion for Catrina and takes it to Gaius. Merlin asks Gaius to make a potion with a similar look of the magic one which would reveal Catrina as a troll, and they set about making it before Jonas awakes in the morning.

The Troll disguises as the lady Catrina to get the throne of Camelot

Still enchanted, Uther continues to be romantic with Catrina, who continues to act as though she is in love with Uther. Catrina questions Uther's ability as a man and a king, stating Athur is not able to take over as king. She states Uther's love for Arthur blinds him to Arthur's weaknesses and that Arthur cannot be trusted. The following morning, Gaius presents Merlin with the replacement potion to take back to Jonas' room. As he does so, Merlin is forced to hide as Jonas returns unexpectedly.

In the city, Arthur comes across a man who has been arrested for not being able to pay the king's tax. As Gwen watches, Arthur releases the man and orders his men to give everybody's money back. In the castle, Catrina and Uther get angry at Arthur on his decision and Arthur simply states he thinks his father is wrong by saying that royalty and the people cannot be equal. Uther demands that Arthur return into the town to collect the payments, but Arthur stands his ground and refuses to do it. After Arthur leaves the throne room, Catrina says that the people of Camelot would not respect her unless she was the heir to the throne, persuading Uther to agree to the request.

Catrina returns to Jonas' room for her next dose of the potion.

Merlin sees the true form of Catrina

As she takes it, Catrina and Jonas leave the room, allowing Merlin to emerge from his hiding spot relieved. In his chamber, Gwen visits Arthur to commend him on his actions in the town earlier that day. Arthur laments that Uther now hates him and that the tax will still be imposed, but Gwen states the people will always remember Arthur's clemency. Arthur says maybe Uther was right in saying he could not be both a king and a friend to the people of Camelot, but Gwen firmly tells him he has a kind heart and he should not change for anybody.

The truth is about to be revealed

After being summoned to Uther, Arthur's title is revoked and Arthur is disinherited for opposing his father causing shock to those in the room including Gaius and Sir Leon. Arthur defends his actions stating he only acted as he was brought up to act but Uther stands firm, sending Arthur away in disgrace.  Catrina is named as the rightful heir to the throne, much to everyone's surprise and confused applause. Merlin rushes to deliver the news Catrina had taken the replacement potion to Gaius, only to be met with the news of her inheritance to the throne. At Catrina's ceremony, Merlin watches from above as she takes her oath. As she does so, her troll form begins to emerge.

Arthur's reaction at the troll's exposure

Catrina snatches the crown and runs from the room to avoid being caught as a troll, only to be pursued by Uther, Morgana and Arthur. Merlin uses his magic to lock the doors and as she tries to open the door, Catrina changes to a troll. Still under the influence of the pendant, Uther is appalled when Arthur reacts

Morgana's reaction at the troll's exposure

disgustedly to the revelation of Catrina's true form. As Arthur tries to convince his father Catrina is a troll, Catrina yanks the door off its hinges and runs away, Uther on her heels. In their chambers, Uther apologises to Catrina, still remaining under her spell and seeing her as beautiful. The next morning, Gaius tells Uther in the council rooms about Catrina's true condition. Uther remains oblivious to his wife's condition and states the next person to insult his queen will be tried with treason and beheaded. Gaius advises Merlin to go to the Dragon for advice as troll magic is very powerful to overcome: however, he advises Merlin to be careful, as the races of dragons and trolls have long been allies.

Arthur has doubts about Merlin's plan

After hearing the story from Merlin, the Dragon laughs uproariously at the thought of Uther marrying a troll. The Dragon says the only way to break the enchantment is if Uther cries true tears of remorse: he also warns Merlin his advice doesn't come without a price, and reminds him of the promise he made to free the Dragon. Merlin goes to Arthur with the proposal if he fakes his own death, Uther will cry tears of remorse. A hesitant Arthur, then agrees to the plan and he takes the poison. Soon after he takes the potion and appears to be dead, Gaius leaves to break the news to Uther while Merlin is attacked by Jonas; causing the bottle containing Arthur's antidote to break.

While Uther cries for Arthur, Catrina tries to lure him away as Merlin mops up the remains of the antidote. Uther, with the enchantment broken, sees Catrina for her true self and becomes disgusted. As Catrina takes on the guards, Merlin revives Arthur. Arthur is knocked unconscious after trying to stop her. Jonas tries to kill Arthur and in turn is killed himself. Arthur, with the help of Merlin's magic, kills Catrina.

Following the night's events, Uther thanks Arthur for exposing him to Catrina though he blames it on magic once again. Arthur is amused over the events, and Uther remains disgusted and ashamed. Arthur thanks Merlin for his help and they share an awkward moment of mutual gratitude.

  • This is the first two-part story in the Series.
  • King Bayard of Mercia from the episode The Poisoned Chalice is referred to in this episode.
  • The Troll (disguised as Lady Catrina) makes reference to her crown having jewels despite having never seen it before she is crowned Queen. When the crown is revealed later its rather plain looking. She may have been making a reference to the crown that Morgana would later wear when she is crowned Queen and of the vision that Morgana has of Guinevere becoming queen in which she is wearing the same crown as Morgana.
  • These episodes are notable for featuring a troll and whatever species Jonas belongs to.
  • These episodes mark the only time Uther becomes romantically involved.
