Question: Throughout season 8, Christy and Billie have been described as the "Ultimate Power" by various sources. Why are they, these two relatively young and inexperienced witches, described as the ultimate power when the battle ready and experienced Charmed Ones have come up against centuries old demons and beings with far more powers, such as The Source of All Evil, Barbas, Zankou, Cole etcetera?SockWearer
Question: There are many instances of these characters manipulating time (i.e. Chris comes back to change the future so Wyatt is good, and there's all that back and forth in the series finale to make things turn out the way they want). Is there ever any explanation given as to why they never manipulated time to go back and prevent Prue from dying? Obviously it was necessary for the production, since Shannen Dougherty left, but is it ever addressed by the characters, plot-wise?
