During the 200th episode red carpet interviews, Adam Glass the writer of this episode talks about the return of Kate
Glass told Tvline: "Her experience, as great Monster of the Week episodes always do, reflects basically where the boys are at emotionally right now. So it will be them looking at themselves in the mirror through Kate and what's happening in her experience."
Explaining the decision to revisit Lady Lycanthrope, Glass said that when viewers last saw Kate, in Season 8's 'Bitten', "It was like The Incredible Hulk, which was pretty cool, as she's walking off. And I think everybody in the writers room was like, 'What happened to Kate? What is her next move?' So the idea of bringing her back is just tremendous."
