What if Chrysalis was less evil than the real Cadance?
Cadance knows about Twilight's taboo feelings for her brother. Prior to the Canterlot Wedding, Cadance makes it clear that Shining Armor will be hers alone, and Twilight will be no part of his life anymore. When Cadance gets replaced by a changeling queen, Twilight uses the opportunity to strike a deal.
