Dean's one night stand with a random woman will end up with an unpleasant result in an upcoming "Supernatural" episode. While investigating a case in a town, Dean heads to a bar and strikes up a conversation with a local named Lydia (Sara Canning). The two go back to her place and spend the night together.
Not long after that, Lydia gets pregnant and gives birth to a baby girl, who grows up very fast. In just a few days, the child has become a teen girl. She then visits Dean to drop the bomb, telling him that he is her father.
In the episode titled "Slice Girls", Sam and Dean investigate a case where the victims' hands and feet have been severed and each have been branded with a strange symbol. Sam does some research at a local university and discovers the symbol on the bodies is a sign of Amazon warriors.
"Supernatural" is taking a two-week hiatus after airing the January 13 outing, and will return with the new episode on February 3 at 9/8c on The CW.
