Marisol broke Knansie the necromancer, out of Tartarus to bring Macy Vaughn back to life when she was a stillborn, by using demonic blood for the ressurection.
But, was Macy the only stillborn ressurected by Knansie? Are there others? Could Julian be her blood brother?
Also, if I understand this correctly, Macy is still half witch and half demon despite the removal of her demonic powers (which sucked because her pyrokinetic power was EVERYTHING). She's still on schedule to turn into a full-fledge demon.
Abigail using a spell to switch it off and transfer it to herself, won't deccelerate the speed in which Macy turns.
Like Cyd said, every person ressurected by Knansie the necromancer turned into a demon.
I don't think Macy will be the exception to that rule, and I don't want her to be.
Because the way I see Macy is very different from how others want her to be. To me, her naivety, her scientific mind, and her purity will always struggle against an abyss where only darkness reigns. At her core, there is a hunger that can never be satiated, thanks to the necromancer's rule and that hunger will feed every impulse denied her. A recovered memory of a reunion with Marisol doesn't fix what's broken in her. She still sees herself as separate from her sisters. She still acts as if she's unworthy. So if her turning into a Charmed demonic witch, will help her access every emotion she tried to deny herself...then I want her to turn. It's who she is...and why should she be ashamed of it.
The demonic blood made her who she is, and quite literally gave her life.
I just wish we knew who it came from. What type of demonic blood is capable of spawning life?
