Understand, Castiel. The plan is not meant to be understood by the likes of you.
Yes. I understand.
Now. It seems that your former vessel has drawn the attention of demons - and of the Winchesters.
Should I -
You will not go to him.
But, if this is still to be my task, how else can I -
Not to him.
Oh. The daughter.
Claire Novak, be not afraid.
I am the angel Castiel, who spoke to your father in a time of need and now speak to you. Your family is in danger, Claire. The world is in danger. I can save your family, I can defend this world, but I need your help to do it.
Do not speak aloud. Feign sleep. Think of me, and I will hear you.
- Castiel. Is this working?
What happened to my mom? Why is she being so -
A demon has possessed her.
And you can get it out?
...but only if I let you take my body. Like you did Dad's.
I... yes. You must consent to my presence in your body.
...there isn't another way?
...there are ways. If a demon hunter or exorcist can be found...
Then, maybe... Dad? Castiel, I think my dad's here!
And you're not gonna...?
Because... he is done. The task Heaven needed him for is complete. Now there is a new task, and a new vessel is needed.
But... Castiel, I'm scared.
You can say no. It's your choice.
...I don't know. I think - aah! Oh my god, the demon shot my dad!
I can save him, Claire. I can save them both.
I - okay! Promise to save my parents, promise to keep my family alive and safe, and you can have my body!
I promise. And thank you, Claire Novak.
