I’ve been ruminating on the page where we see blood flowing from Wanda’s wound, which is where her womb is, and from flowers springing forth from it. It brings to mind birth and life. According to Eye Boy, her blood is filled with magic. Leah mentioned that she wanted chaos magic to be a positive force for Wanda. Perhaps chaos magic itself is what is reviving her, and her soul is on the Witch’s Road, where Billy can’t reach her.
