Suppose a witch creates a soulbound doll. Can she use parasitic soul to move the soul of the doll into another creature?
Although the soul in the doll did not end up in the soul focus of the doll through soul bind or trap the soul, the creation of the soulbound doll does include a receptacle suitable for magic jar that contains a soul placed in the soul focus by the witch, so I'm inclined to think the answer is yes. However, I'm interested in what other people think about this combination.
