Lydia is an Amazon.
While investigating a series of murders, Dean takes time out at the Cobalt Room, where he meets Lydia, and they end up back at her place and have sex. When Dean returns the next day to retrieve his hip flask, he finds that Lydia has a baby called Emma, which he thinks he hears speaking like an adult. Dean stakes out Lydia's place, and later sees her hand over a young girl, who she also calls Emma, to Madeline.
