Merlin tries to persuade Arthur to reconsider his decision as they leave the meeting, but he refuses. Tyr tells him he has no name to give him, which causes Arthur to sentence him to death. Tyr denies all the things he is accused of, but Arthur does not believe him and asks him to reveal the names of his accomplice. Tyr is brought before Arthur who questions him. Gelda does not believe her son has done anything wrong, but Percival finds the thread that was used to re-stitch the girth of the saddle. Leon then goes to Tyr's mother Gelda Seward and informs her that her son has been arrested in suspicion of treason, whilst the other knights look around in the house. The confused Tyr is taken away by the knights. Gwaine then goes with two knights to Tyr Seward, the stablehand to the King and arrests him. After hearing this, Arthur says that Merlin may be right this time about this not being a coincidence. Sir Leon then arrives with a guard, and shows Arthur his saddle that had an unpicked and re-stitched girth which was designed to make the saddle break. Arthur wonders if the men who attacked him were questioned, but Gaius replies that their wounds were so fatal that it was impossible to learn anything from them. In his chambers Gaius treats Arthur's wound and tells him that he is fortunate not to have broken his neck.

Arthur is clearly shocked by what happened, as is Merlin. He fights them off, with a little help from Merlin, and finally defeats them. A moment after he hits the ground, he is attacked by two bandits. On the ground nearby there is a small bag which explodes and causes Arthur to fall down from his horse. It is their anniversary, and they speak of how Arthur forgot about it and both Merlin and Guinevere had to remind him that it was that day. Darkness steals into the very heart of Camelot, as Morgana and her puppet Queen hatch a sinister plan to murder the King, but when stable hand Tyr Seward becomes caught in the crossfire, he threatens to ruin everything… As the plot thickens and reaches its deadly climax, can a suspicious Merlin unravel the truth before it’s too late? Plot Īrthur and Gwen are on a ride with Merlin.
