Who Saves the Saviors

With Ilthuran's support, Gwyn challenges Ascencia to a duel. Dal, Jankom, Zero and Maj'el are captured by the Diviner's men and find themselves in the same holding cell with Captain Chakotay and his first officer. In spite of his best efforts to not disrupt the original timeline, which could result in Gwyn never being born, Dal ends up dropping a phaser which Chakotay uses to get into the Protostar to escape. This causes Gwyn to physically phase in and out, and she loses the duel.
