Thread:The Dark Lord of the Sith/@comment-3298705-20140720030729

As the season progresses, we find out that Count Dooku is not the Sith Lord, as the Jedi were made to believe.
 * Obi-Wan: "When Dooku first mentioned Sidious to me, I thought he was lying. It's possible he was trying to cover his scent." - Here, Obi-Wan explains that he thought Dooku was the Sith Lord and that "Darth Sidious" was a lie conjured by Dooku to hide this fact.

When the Jedi discover there is another Sith Lord out there, the hunt for him begins.
 * Episode I - Vos leads an attack on a Separatist base where Darth Sidious and Count Dooku are present. He is on an assignment from the Jedi Council to discover the identity of the Sith Lord. Rather than take the base, as Vos tries to make it appear, he allows his clones to get killed, or so it seems, and allows himself to be taken prisoner. He is brought before Sidious and Dooku, just as he wanted. When he tries to remove Sidious' hood to find out who the Sith Lord is, the Sith's eyes glow yellow and Vos reels back in pain, his head burning. Images of Sidious and Dooku appear in his mind, taunting him and chanting, their eyes both glowing intensely, hands waving as if casting a spell. Vos lets out a scream, his face darkened, eyes yellow, his dark side tapped into. He starts to attack anything and everything in the room, but Sidious and Dooku team up to incapacitate the Jedi.
 * Quinlan Vos is now under a Sith trance. Sidious is using Vos as a test dummy for Anakin Skywalker; the only way to turn a Jedi to the dark side against his will, it is revealed, is through a trance. Sidious first tries this trance by directly infusing Vos with his dark side; he finds out from seeing how unstable the trance and sudden surge of the dark side made Vos that if he is to seduce Anakin in a similar fashion, he will have to be more subtle. In Revenge of the Sith, the trance Sidious applies is his words to Anakin regarding Padmé.
 * Episode II - Dooku takes Quinlan Vos back to Serenno and uses him as an assassin. Sometimes, Vos's trance is in effect, other times, he is merely pretending to gain information on Darth Sidious. In the end, Vos's dark side gets so out of control that he attacks Dooku. The two duel, and Vos overpowers the Count. Using Force Lightning on him, the Count is stunned long enough for Vos to escape. Rather than pursue him with an army of MagnaGuards, Dooku decides to let the rogue Jedi get slaughtered by his own allies, who will have no other choice of action when they see that their comrade has fallen to the dark side. Vos has served his purpose as Sidious's "test dummy," as well.
 * Episode III - A clone trooper from Vos's squad managed to survive the carnage at the Separatist base and returns to Coruscant to report to the Jedi Council that his general is missing. The Jedi discuss among themselves that Vos could have fallen prey to the Sith on his mission behind enemy lines. It is decided that Anakin and Obi-Wan are to search for Vos and retrieve him. The two Jedi find Vos's tracking signal on Serenno, where they confront Count Dooku. The Count duels the two Jedi, and mid-duel, Anakin says, "You just can't hang on to an assassin, can you, Dooku? First you lost Ventress, and then you lost that monster." This gives Obi-Wan an idea that he does not reveal to Anakin until the pair manages to overpower Dooku. They learn from Dooku that Vos is not on Serenno after all; the Count says that, "Since the Jedi you're searching for is not here, there is no more need for you to waste my time." He allows Anakin and Obi-Wan to leave so that he may contact Lord Sidious. Dooku is to retrieve (or eliminate while trying) Quinlan Vos as well. As Anakin and Obi-Wan leave Serenno, Obi-Wan claims he knows the perfect person to retrieve Vos: Asajj Ventress. Anakin reluctantly meets with Ventress in a bar in the Coruscant Underworld; he guarantees her full pardon if she helps to recapture Vos. Ventress eventually agrees, and she finds Vos on a distant planet. The two engage each other in a climatic duel, from which Vos emerges victorious. In a dark side rage, he kills Ventress; this action breaks him out of the trance for good. Consumed by guilt, Vos returns to Coruscant, where Ventress is given a funeral - she is hailed as a lost Jedi who become a hero once again in the end. Quinlan Vos is prepared to take punishment for his actions, but the Jedi forgive him and admit him back into the order, saying they can't afford to lose more allies when the dark side's hold on the war has been intensified so by the revelation of Sidious's existence. Vos states his memories of his time behind enemy lines are foggy or gone entirely, and Obi-Wan speaks to Yoda outside the Senate Building about how concerned he is that the Sith were able to manipulate Vos through his dark side. He fears that the Sith Lord could control Anakin, who has at times veered too close to the dark side, in a similar manner, to which Yoda states that a closer eye must be kept on "Young Skywalker." Yoda reveals that the war is coming to an end, the dark side grows stronger every day, and as the two Jedi walk off, we zoom up to Chancellor Palpatine's quarters. The old man is staring down at the Jedi as they leave the vicinity of the Senate Building; he smiles evilly.
