Season three episode four of Game Of Thrones is all about revenge. The final minutes of the episodes were a stunning crescendo, with the masters of Astapor learning that "a dragon is not a slave," in the worst possible way. The episode was arguably the one instalment of the season that wouldn't have looked out of place on the big-screen - it had real cinematic moments, thanks to director Alex Graves.

In the episode - And Now His Watch Has Ended - Peter Dinklage's Tyrion discusses the Battle of the Blackwater with Lord Varys. Does Varys have proof that the Queen tried to have Tyrion killed? Elsewhere, Diana Rigg's Lady Elenna meets with Varys to discuss her interest in Sansa

In the North, Bran has another of his crazy dreams where he is running through the woods with Jojen Reed chasing the tree-eyed-crow. He climbs a tree in pursuit of the crow, but falls when he sees his mother who begs him not to climb again: but what does it all mean? Over in the Riverlands, Arya, Gendry and Sandor Clegane are being transported to the hideout of the Brotherhood without Banners by Thoros and his men. There, they are introduced to Beric Dondarrion, to calls Clegane a murderer - something he refutes. Arya tells the Brotherhood of Micah that Clegane killed. 

It appears the critics found the episode the most entertaining of the season so far. Matt Fowler of IGN wrote, ""Shocking deaths, brutal double-crosses and a Kingslayer undone made for some mighty fine Thrones."
