Editor's Note: The following contains spoilers for A Knight of the Seven Kingdoms Episode 5.After building up the last couple of episodes, A Knight of the Seven Kingdoms finally reveals the Trial of Seven on screen in Episode 5. After Aerion (Finn Bennett) is attacked by Dunk (Peter Claffey) at the end of Episode 3, and Egg (Dexter Sol Ansell) reveals his true identity to his companion, tensions have been high. Refusing a one-on-one match against Dunk, Aerion instead calls for a Trial of Seven to settle their problems. While Aerion has his father, Maekar (Sam Spruell), his brother, Daeron (Henry Ashton), three kingsguard, and the recent turncoat Steffon Fossoway (Edward Ashley), it's a bit more difficult for Dunk to find the other six knights he needs for his side of things.
