The Past
Winnie's eyes dimmed as she remembered all her pain in the past.
Black didn't need to say who sent him.
Without a doubt, she knew it was Ivy.
So, after all these years, she's decided to finish her work.
Back then, she and her children were hunted down and saved at the last minute by Santa, who then brought them here.
Never again would she ever wish to be in such a helpless predicament.
As for Ivy, coupled with her insane jealousy of Winnie's glamorous life here, another thing that might've pushed her to kill urgently was because of fear.
Right now, Winnie held a certain degree of power here, which terrified Ivy, giving her sleepless nights.
What if Winnie decided to seek revenge?
In fact, Winnie won't even need to send assassins to take her down sneakily.
As someone with power, she could straightforwardly state her claim that she was wrongly prosecuted back then and put pressure for Ivy to get punished.
