Anything on the Supernatural mid-season finale? I can’t wait for more Jack! — Jane
Yes, Jack is back, and he’s on a mission that will introduce him to newcomer Kaia, a dreamwalker. But there’s still the question of whether Jack is good or bad, which will be answered — at least for the time being — by episode’s end. Also by episode’s end? A major cliffhanger that will set the stage for the Wayward Sisters backdoor pilot. Let’s just say it’s something Sam and Dean have never dealt with before.
 An interview with Robert Berens and Andrew Dabb on Kaia and this episode.
The official title for Kaia is a dreamwalker, and let’s just say that title makes her important, and not just to a potential spin-off. “We’re introducing Kaia in [episode] 9, but it’s not just for the purpose of the spin-off,” executive producer Andrew Dabb says. “She’s very vital in the mythology we’ve been building toward the entire first half of our season.” Speaking to how the introduction of both Patience and Kaia compares to the series’ first spin-off attempt with Supernatural: Bloodlines in season 9, Dabb continues, “These characters are a part of the DNA of our show and we wanted to bring them organically into the fold in a way; to be completely frank, Bloodlines we didn’t. [Bloodlines] kind of dropped you in the middle of a whole other story. So Kaia is important to the spin-off but she’s also important for Sam and Dean, and that will allow the audience to really sympathize with her, understand her, and see what she can do.”
