What will merlin series 4 be about

Arthur is led to said stone, where Percival, Leon and the assembled citizens of Camelot are waiting - they've all been rounded up by Merlin, with the Dragon's help.

At first, Arthur struggles to remove the sword, but Merlin assures him, "You're destined to be Albion's greatest king.

With a little help from Merlin's magic, Arthur pulls Excalibur from the stone - his faith restored! But back in Camelot, the warlord Helios reports Agravaine's death to Morgana.

Emrys is indeed a busy boy - as night falls, Merlin sneaks back into Camelot, transforming himself once more into the elderly Dragoon. Incapacitating a guard and stealing his cloak, Merlin reverts to his younger self, but not before a terrified Morgana has caught a glimpse of 'Emrys' A frantic Morgana tries to sleep, but Merlin has already planted a magical item - similar to a voodoo doll - beneath her bed. Back in the woods, Tristan and Isolde ask Arthur if they may fight at his side - both have been impressed by the honour and leadership he's displayed.

Armed with Excalibur, Arthur leads his army to Camelot - the King's forces clash with Helios and the Southron warriors. While Percival and Leon rescue Gwaine, Elyan and a weakened Gaius from their cell, Arthur leads an assault on the throne room, where Morgana is waiting But thanks to Merlin's interference, Morgana has been robbed of her magical abilities. Morgana is wounded by a knight of Camelot as she makes her escape, while Arthur is likewise injured by Helios.

Isolde saves the King before Helios can strike the killing blow, but Helios then mortally wounds her as he falls. Tristan holds his love as she dies Meanwhile, Guinevere bravely confronts her former friend Morgana. Tom Hopper as Percival. Rupert Young as Leon. Adetomiwa Edun as Elyan.

Hopefully the others will be given more to do in the upcoming episode other than wave swords around and make the odd comment. On the subject of being given little to do, Gaius is still played with calm reserve by Richard Wilson, dispensing mystic portents and medicine to those who need it and moving the plot along when we encounter a bit of legend or lore.

On the plus side, the story was a well paced romp that struck a good balance between action and plot, whilst setting up for what will hopefully be an interesting series. It definitely sets things up for an interesting part two next week. Skip to main content area. This review contains spoilers.
