Both are theories. What if Irene enchanted something into Ezra? Like she did with her two underlying that were originally swords. It could be Ezra gain independence from Irene and turned into a real human. So now she wants her dead as she can't stand one of her creation not bound to her.

Or that Irene is her mother and during the pregnancy there was a problem, and had to deliver her emergency C-Sectioned. Could explain her lower torso scar.
