Andrew Dabb, the one who penned the "Bloodlines" episode, which airs tonight, recently talked to TV Fanatic about what fans can expect from the backdoor pilot of the new series. "Family has always been the core of Supernatural. It's what has allowed the show to keep going for years and years and family being not the family you're born into but the family you make along the way...Bobby was part of the family, Castiel's part of the family and Crowley is like the weird uncle in the family," Dabb said.

"We're inheriting a lot of the rules from the Supernatural...I think what's been established from Supernatural is going to be kind of our governing force. In terms of, you know, what killed the monster and how the monster changes. Where we feel we have a lot of room for kind of building and a kind of experimenting are in the monster dynamics for the characters...so even if they are a monster you'll know where they're coming from," Andrew Dabb added. When asked about possible crossover from Supernatural world to Bloodlines, Dabb says: "I think where you'll see a crossover initially is with some of our supporting characters. There are characters like Castiel, Crowley, Garth, Jody Mills, people who are from the Supernatural world that I think could be passing through Chicago. And again, the fun of Bloodline is, unlike Supernatural, which has a character show up for an episode and be gone the next episode because the boys have moved on, we'll be bringing a character like a Jody or a like a Garth and have them around for three or four episodes and really kind of explore story lines with them."

As of late, the Winchesters has learned that Abaddon is harvesting souls across the country to come up with a demon army. Dean had this contact with The First Blade, and he even found the combination of it and the Mark of Cain overwhelming. Fortunately, Sam was able to break Dean's blade-induced bloodlust. Surprisingly, Crowley double-crossed the siblings and took away The First Blade, telling them that he is only willing to give it up once they are ready to slay Abaddon.
