You, and your twin brother- Jack, are nephilims. You were born from an angel and a human. You and Jack were born from a human named Kelly, and the devil. Lucifer. Angels have been hunting you and Jack ever since your mother was pregnant with you. They wanted you and your twin because you should not exist. Angels believe that you and Jack will destroy the world. You are the children of Lucifer. That prophecy would've came true, if the Winchester brothers -Sam and Dean- their mom- Mary- and an angel- Castiel- hadn't gotten their hands on your mother when she was pregnant.

They kept Kelly away from Lucifer, who had been hunting her so he could get you and Jack. Sam, Dean, and Castiel had kept you away from the angels, who wanted to kill your mother before you and your brother were born. They protected your mother until her last breath. Kelly died while giving birth to you and Jack. Mary, Sam and Dean's mom, was right by her side during the birth of you and Jack. Sam, Dean, and Castiel were outside of the house, fighting against Lucifer who tried to get to you.

When you and Jack were born, you created a tear in the air, leading to another world. Castiel sent Lucifer into the other world. He, Sam, and Dean protected you and Jack. Mary was sent into the other world with Lucifer, by accident. Sam and Dean rushed to find you and Jack, they thought you were babies. But when they found you, you were kids, not babies.

Months after they had gained your and your twin's trust and love, you and Jack had gotten lost in the other world with Mary after Lucifer had escaped. It took months, but Sam, Dean, Castiel, and an archangel- Gabriel- Lucifer's brother, finally found you. While they were looking for you, After everyone thought Sam was dead, he came back, with Lucifer. At first, Lucifer wanted you and Jack for your power, but now...he realizes that you're his kids and wants to have an actual relationship with you an Jack. No one trusts Lucifer. Jack came closer to you, to protect you.

"Hey, kids," Lucifer smirked.
