@Disconnected the witch is probably Ian's mother, base on her story that she left her family for their safety and silently protecting them. Let's also consider the fact that the talisman she gave Joel/Li You, Ian's able to touch it when supposedly Joel/Li You's the only one able to touch it. And he can also do magic, divinity and can see dream demons.. Yep definitely Ian's her kid. She even asked Ique/Mara to deliver a magic book to Ian..
