I wouldn't be here if it weren't for you. So now someone has to kill someone. Emma to her father, Dean

Emma was an Amazon conceived by Lydia and Dean during a one-night stand, unbeknownst to the latter. After trying to kill Dean, Sam shot her, killing her instantly.

Season 7 Born a mere two days after her conception, Emma aged fast, as was customary for Amazons until she reached sixteen years of age whereby the aging process became normal. While still in her crib as a two-year-old, she was able to communicate with her mother by talking. Dean saw her and was confused by the sudden appearance of a baby but was shocked to see her talk with Lydia. Later on, he and Sam learned about Amazons and discovered that Emma was Dean's daughter.

When she grew up to 6 years old in a few hours, her mother sent her away with the Amazon leaders who had her undergo intensive training, including consuming human flesh with milk and being branded with the mark of the Amazons before being sent to kill her father and uncle (since they were threats) to complete her initiation.

Emma was revived,Emma has blonde hair and white skin and green eyes and a yellow green jacket and a pink blouse and black blue pants he is walking
