Prophecy (1) - S1-E1
Continuity mistake: At the beginning of the episode, Kahlan Amnell, and her sister, Dennee Amnell, are escaping the soldiers of Darken Rahl on horseback. There is one scene, as the ladies are riding, that you should take notice of how many times Denee and Kahlan change positions while riding away from the soldiers in several quick shots - sometimes Denee leads while other times she is behind; then, sometimes they are riding side by side. Also take notice that Denee gets struck by an arrow while she is leading Kahlan in the chase. Then you see Kahlan looking over her shoulder in terror because her sister has been shot.
