- Although Cinderella may have wanted to grant a pardon to Lady Tremaine and Drizella after they became lowly servants at the Palace, the King would most likely feel the need to either keep them as servants or have them exiled to protect both her and Anastasia. This would thus prevent Lady Tremaine from getting her hands on Cinderella or Anastasia, or even being able to return to her château and recalculate her plans.
- Furthermore, even if Lady Tremaine and Drizella were allowed to leave the Palace, Cinderella and the King would doubtless do everything they possibly could to protect Anastasia, thus preventing a potential regression.
- Further to that, all 3 segments of Dreams Come True took place before Cinderella's first wedding anniversary, during which Anastasia and Drizella were enslaved by their own mother. At the end of An Uncommon Romance, Lady Tremaine quite willfully disowned Anastasia, while the latter continued her romance with the Baker and grew closer to Cinderella, with her mother now securely out of the way. One can only assume that in the case of A Twist in Time, the existing aftermath of the first film was amended, showing Tremaine to have taken full advantage of Anastasia and Drizella in Cinderella's absence, enslaving them and preventing them from being able to seek any escape.
When Tremaine discovered that Cinderella was indeed the mysterious princess at the ball in the first film, and also when Cinderella managed to produce the second glass slipper, the intervention of Fairy Godmother (or some other form of magic) was most likely the only conclusion Tremaine could reach as to how either of these events could happen, which would thus make her a Secret Secret-Keeper.
This also raises an even more frightening possibility that Lady Tremaine eventually finding the wand was inevitable, even without Anastasia or Drizella coming across it. It could be argued that the only reason Lady Tremaine hadn't sought out the wand sooner was simply because she was trying to keep suspicion down for as long as she believed was necessary, so she could eventually seek out the wand herself and set her plans in motion to ruin Cinderella's happy ending, and live in the Palace.
Lady Tremaine's endgame may well have ultimately been to take full control of the kingdom, through either marrying one of her daughters into the royal family and covertly disposing of the King, or, as was more or less hinted at in the ending, seizing it by force.
- Lady Tremaine hints at this earlier on in the film as she continuously dismisses the power of Cinderella and Prince Charming's love for each other as unimportant compared to the power of the wand.
- Tremaine's fixation with marrying her daughters to those at the top of the social ladder and gaining access to the Palace also hint at this possibility.
- This also raises the prospect that if Lady Tremaine was able to turn Cinderella, Anastasia and the Prince into toads, she would have most likely done the same to the King and Grand Duke, and would have been able to force the entire Kingdom to bow to her demonic rule.
- It also brings in one final, terrifying possibility: If Lady Tremaine had found the wand before either of her daughters, she may have thrown her original plans to marry them into the royal family right out the window, and resorted to seizing the kingdom in a violent coup, relying purely on the wand itself.
Bottom line; it was probably never just a long-term personal vendetta against Cinderella, but a far grander, and far more devilish attempt at seizing absolute power.
