-----------------------------------------------------------------------------------------------

The only difference between you and your twin brother is that you know how to control your powers a lot better than he can. You're one of the famous Nephilim twins that your mother bore right before she died. She couldn't handle the power you and your brother shared, and her body gave out before you even saw what she looked like.

It was weird because while in the womb, she would talk to you and Jack with such love and appreciation. The only difference is that Jack took what she said to heart while you took it in the opposite direction. She'd talk about an angel named Castiel and your brother would flourish at his name. She refused to say your real father's name, but you heard everyone else talk about it. The difference between your brother and you is that he listened to her while you listened to the people around her.

Your powers allowed you to drown out the sound of her voice and to focus on others around her. They talked of your real father, Lucifer. They are the ones who decided it's best to keep him out of your life. They thought he was bad so they decided for you. When you were born, you tried keeping up the facade that you were on board with the whole "hating Lucifer" thing, but you couldn't keep it up anymore.

Sam, Dean, and Castiel knew there was something off about you from the moment you were born, but Jack knows you better than anyone else. It's almost as if he knew what you were thinking because one of the first words he ever said to you was something about Castiel.

"Brother, why must you bother me with this? I'm clearly on board with you and the Winchesters," you sigh.

"We share the same blood and power. I know what you're feeling. You doubt Castiel and the Winchesters. They know what they're doing, and they've been doing it their whole lives. You heard what Mother said about them."

"Lucifer, our real father, may not even be bad. We've only heard what our mother says about him. How has he proven what they say is true? He hasn't warranted otherwise. He's not a bad guy, Jack," you try to convince him to join your side.

"How can you say that after what Mother said about him?"

"That is one person's perspective. That is not mine. My—Our story could be different. He needs us, Jack. Don't you feel his pull?"

"Y/N, Castiel has been nothing but good to us. It's in our best favor to side with the good guys. Please, Y/N, for me," Jack begs.

"Fine, brother. I'll do it your way," you sigh.

Unbeknownst to him, you have your own agenda you're going to follow.

It's taking a lot of work on your part, but you have been deceiving your foster family into thinking you're on their side. Your father has been teaching you how to harness your powers and to be in control of them. Your brother lacks in this department since no other being knows how to properly teach him. Sam and Dean can't, and Castiel isn't half the angel he used to be.
