Sylvanas's "whitewashing" may feel slightly abrupt to many players, after the legion and BFA two big expansion film villains paved, only a small version of the shadow world, all the preparations have collapsed, it feels like two different screenwriters wrote the plot. However, the plot of the 9.2 version makes Sylvanas's whitewashing have a very reasonable plot support, and even goes back to the content of WAR3, all the faults "not my intentions" and the way of self-redemption can once again make the Queen of Greece a decent role.
The Queen of The Sheki strikes back at the Warden Zovar because the Warden tries to create a whole new world that completely succumbs to him. This made Sylvanas instantly recall the painful past of being controlled by Alsace, and the Battle of the Sun Well turned Sylvanas from a Ranger General into a "Banshee King" controlled by Alsace. WAR3 doesn't depict Sylvanas becoming a banshee and regaining her freedom, especially the inner depiction of Sylvanas's transformation, which then transitions directly to the Dark Queen of world warcraft's forgotten boss.
In the shadow world, Sylvanas is "ruled" by the warden, and the dark side and self-aware puppet are the main state. In this state, the Greek Queen's rebellion in the "Holy Place" can only be said to be an unexpected and absolute surprise, but it is also difficult to explain the statement that the Greek Queen is "controlled", because being able to strike a blow against the warden shows that Sylvanas is actually self-aware, which cannot throw the past crimes to the dark side controlled by the warden.
Version 9.2 has a short cutscene in which Sal, Gianna, Berval, Sylvanas and Anduin stand together again, not to judge Sylvanas, but to restore Anduin's confidence. After Anduin was rescued from the warden's control, and unable to get out of the shadow of his memories, Sylvanas began to use his memories to guide Anduin, which is the psychological process of the struggle between the Queen of Hee and Alsace, and also explains why Sylvanas was able to suddenly break with the warden in the "Sanctuary of Dominion".
During his control of Alsace, Sylvanas still maintained a strong impulse to "free will" in his heart. When Alsace appeared during the weakening period, the Queen of The West shot an arrow at Alsace in an attempt to become alsace's judge and executioner. Sylvanas's absolute hatred for Alsace comes from "I can personally punish Alsace's crimes, I can achieve self-redemption", after Alsace was destroyed, the Greek queen desperately jumped off the cliff is the collapse of self-redemption failure.
Sylvanas uses his own experience to guide Anduin out of the shadow of control, that is, To face up to all the mistakes committed during the period of control, and to redeem himself by defeating the warden. As a result, Anduin regained his self-confidence and gained the strength to fight against the "power of dominance".
In short, Sylvanas is not actually a "whitewash", because the Queen of Hee herself has not denied the past crimes, which should be called "redemption". And Sylvanas has a thorough understanding of how to redeem himself, that is, to eliminate the culprit, previously tried to blade Alsace, and now defeated the warden, all of which are the self-redemption paths of the Queen of The Sea, including Anduin's current state, but also to defeat the warden to achieve redemption, because Anduin also committed many crimes during the control of the warden.
