Some "Supernatural" season 11 spoilers were shared by producers Andrew Dabb and Jeremy Carver at Comic-Con International in San Diego. Among the spoilers were about the characters Amara and Rowena to be played by Emily Swallow and Ruth Connell, respectively.

Amara is the Darkness character who Dabb said is very interesting mainly due to her being very alien to the world because since the dawn of creation, she has been locked away. In "Supernatural" season 11, Swallow's character is set to cause trouble to the Winchesters played by Jared Padalecki and Jensen Ackles.

"There are ways, because the Darkness is such a big thing, to connect a lot of our different characters in terms of the impact on the witches, the impact on Hell and on Heaven and on the guys," Comic Book Resources quoted Dabb as saying. "We're hoping she will have a big ripple effect for us."

Like Amara, Dabb said Rowena is also an interesting character who is kind of put aside for most of her career as a witch and was never the top dog. In "Supernatural" season 11, Connell's character will have a dilemma whether or not she really wants her newly found power.

Rowena is the mother of Crowley (Marco Soriano). In March, Connell told Entertainment Weekly that she hopes Rowena "gets to fly at some point."

In addition, Carver revealed that they are doing an entire episode in the Impala, which will be Supernatural" season 11 episode 4 titled "Baby." The new season is set to premiere on The CW on Oct. 7.
