⚪︎Master Vernestra's explanation at the Senate
"16 years ago, four Jedi were stationed on the planet Blendok and discovered a witch Force cult. A conflict ensued, resulting in many casualties. The four conspired to cover up their actions. Recently, the truth was almost revealed, and the tainted Jedi Sol killed his accomplice to protect himself.
On behalf of the High Council, I condemn Sol's actions. I can state with certainty that this is a tragedy caused by one corrupt man."
I'm amazed at Plagueis's clever manipulation, which successfully concealed the existence of the Sith.
I was worried about the number of Jedi casualties, but he cleverly manipulated the delicate situation!
"The dark side of the Force is clouding the eyes of the Jedi."
Vernestra is impatient. She was frustrated that she couldn't resolve the situation by not reporting it honestly to the Council. The Sith took advantage of her impatience.
⚪︎Setting up
Lure Sol and May to Blendok, and send Kymir and Osha to Blendok as well. Reunite May and Osha and reconcile.
Discover the truth and make Sol the enemy, believing that he killed his mother. All that's left is for Kymir and the two of them to eliminate Sol.
Plagueis found out from Kymir, objectively analyzed the incident 16 years ago, and saw through it as Sol's mistake. He made good use of that.
It went as planned, and he was also able to make Osha Kymir's apprentice.
Varnestra would never imagine that there was a master above Kymir.
(Plagueis makes his apprentice have an apprentice. He deceives them by making them aware of the rules of the two)
⚪︎The Jedi was one step too late
By the time Vernestra and the others arrived at Blendok, Sol was dead and May and Osha had left.
Kymir's former master (Varnestra) had come to Blendok!
It seemed that both of them felt his presence.
Perhaps Vernestra has something she wants to hide about Kymir. And Kymir also wants to avoid confronting Vernestra at all costs. (Plagueis knows)
This is convenient for concealing the true nature of the Sith!
Vernestra and the others have not seen Kymir. They erased Mei's memory.
This way, Mei will not reveal anything about Kymir, and Sol is a corpse.
At the same time, Osha has defected to the Sith.
⚪︎Did Yoda notice?
Yoda, the head of the Council, was shocked by the large number of Jedi casualties.
But he could not see that the Sith were involved. Because there was no evidence.
He wanted Sol to be alive. . That must be what he felt. Was Sol really the only one who betrayed him?
If he had made Sol honestly tell the truth about what he had been hiding, Yoda would have been able to grasp the existence of the Sith. It would have been a hindrance to Plagueis as well.
It was Yoda who made the Council's final decision on whether to train Mei and Osha. He must also be regretting the death of Indara, who reported to the Council at the time.
"The dark side of the Force is hard to see."
Perhaps Yoda can restore May's memories?
