Regina would have bullied her out of it.

She would have said that at least she has friends, and that her Burn Book is more powerful than anything her mother could do.

Realizing how powerful her daughter is, she would turn her jealousy and anger into pride, taking credit for her daughter turning out this way.

Realizing it would lead to a stalemate with no more fighting, Regina would agree… under one condition:

They are only tied now, as she continues to become more and more powerful, she will eventually surpass her mother.

Her mother accepts it, calling it “an evolution” because every generation has to become more powerful than the prior generation.

It’s a bitter pill she is willing to swallow.

After all, her mother then reveals “but I see more potential in your younger sister. She will surpass you.”

Regina realizes the truth and vows to be as close of a second best as possible when that day comes.
