■Gwen has been looking after the King during the period of time between the series.[10]
■A sword will be burned near the start of the series.
■There will be more Knights of the Round Table.
■Agravaine will be the new enemy within the walls of Camelot, laying a claim to the throne.
■Merlin will try to discover his destiny as Emrys, and will find out there are massive reasons why he can't reveal his magic.
■Morgause and Morgana will start looking for Emrys, unaware that he is Merlin.
■Merlin will somehow be stripped of his powers (possibly temporarily).
■Lancelot has a major role in Revival of the Witch.
■The Arthur/Gwen/Lancelot love triangle will be a major plot line.
■Lancelot will be declared dead, which causes mourning among Merlin, Arthur, the knights and especially Gwen.
■There will be more stories about Uther's past.
■Arthur and Gwen will become engaged.
■The way Lancelot is portrayed may be substantially different from the legends.
■Morgana's magic has finally become as powerful as Merlin's, and possibly more powerful than Morgause's.
■A battle for power will occur between Arthur and Uther.
■Morgana becomes quite nomadic, moving from one place to another.
■Lancelot will meet the Great Dragon.
■Grettir will make an appearance.
■The Isle of the Blessed will reappear.
■Gwen and Morgana will learn about Merlin's powers.
■Hunith will return.
■Merlin and Gwen's friendship will be explored this series.
■Gwen and Lancelot may be under a love enchantment, causing a fight between Lancelot and Arthur. In the official trailer, Guinevere is shown to be wearing a suspicious bracelet, while kissing Lancelot. What's more Lancelot shows suspicious behavior, since he attacks Arthur. (Up here is possibly true) The most likely possibility is that Agravaine has put a spell on them with Gilli's help causing a fight and trouble. (This is less likely due to Gilli is not confirmed to be in the series yet, if he is where's the proof?)
■Merlin will have a new reason to hide his magic from Arthur.
■Arthur will learn the truth of his birth again.
■There will be an episode that focuses solely on dragons and the future of the dragons.
■Uther is in a mental state that prevents him from ruling so Merlin gets the biggest chance that he's ever going to get, to guide the future in the direction that he wants, the destiny that he is set to achieve. He wants to see magic return to the kingdom under the rule of Arthur.
■Merlin is going to struggle keeping his friendship with Arthur going on, but he is met with a wall and he's not sure how to deal with that.
■Merlin's greatest fear is a reincarnation of Uther in Arthur: if there's any sign that Arthur is thinking like Uther, then he can never bring his magic to the foreground. He can never get the kingdom he wants to have.
■Merlin will dress like a knight of camelot. (Not sure why thought but was confirmed by Colin Morgan) [11]
■Arthur is walking towards the very noble, heroic king that is spoken of in the legends.
■There is someone or some people/creatures who have no faces who attack a village.
■There will be a dragon egg in one of the episodes.
■Uther is closer and warmer towards Arthur. There's some really nice, emotional stuff between them.
■As per usual Uther and Merlin will have just a little interaction.
■Merlin will be sympathetic towards Uther but ultimately loyal to Arthur.
■We'll see a lot more from Arthur's knights as their characters are explored.
■We can expect series 4 to be darker and to see the return of Excalibur.
■With Uther a broken man, Prince Arthur has the emotional dilemma of either taking charge or waiting for his father to recover.
■Uther is a broken man this series and this leaves a power vacum in Camelot which leaves Arthur with a choice.
■Somebody is going to be burnt at the stake
■Morgana is pulling an old wagon, whose contents are covered. Her face is covered by a hood. Knights of Camelot approach and inquire where she is headed. She says the Sea of Meredor. She turns and Leon says “The Lady Morgana!” to which she holds out her hand and leon goes flying backwards. She continues to do this for the remaining knights. When she’s confident they are incapacitated, she pulls down the covers of the wagon to reveal Morgause, and asks if Morgause is okay. Morgause says yes, but they have to hurry.
■In the blooper reel, someone will temporarily wear Merlin's costume and serve Arthur
