The Darkest Hour (2) (S04E02)

As the kingdom teeters on the edge of disaster and Morgana prepares to attack, the opening episode of this fantasy drama reaches its climax. While Lancelot hurries back to Camelot with the gravely injured Merlin, Arthur forges ahead on his quest to defeat the Dorocha alone. The Knights are well aware that their path to the Isle of the Blessed is perilous, yet none can foresee the profound sacrifice Arthur is willing to make there. Their bonds of friendship and loyalty are pushed to the brink, but ultimately, it is the strength of love that transforms their lives forever.
