I need to knowwww

This is just my conjecture, but it totally looks like black magic of a sort since its all swirly and sh*t. Plus, when she felt it in the beginning, it was a prickly sensation.

I agree!
but then he clearly crushed it by stepping on it, but nothing happened so im like whaaaat ????

But that makes sense imo bc he has the holy powers or whatever and they (magic vs holy powers) are diametrically opposed to one another.

ahh I see, so instead if activating the magic he stopped/cancelled it -- thanks :)

Nah, I feel like you already knew it. Just needed a little nudge in the right direction. :)
