If Sodder and Sam allowed me to actually leave? Sure, I could try. Maybe I'd hop on over to a more appreciative vessel. One that isn't keeping me prisoner because he's decided to have a teenaged rebellion at age 30.

[He shrugs, not particularly convinced that Jack could align any of those stars anyway.]

... You sure seem to care a lot, though. About what this Sam Winchester does. About his circumstance. [He cocks his head to the side, brow furrowed.] I can appreciate someone who cares about Sam almost as much as I do. Someone who just wants to help.

You see, I want to give Sammy the world.

He just hasn't seen the full picture yet, of how great it'll be. Dean and Castiel, his parents, his family and friends... I could make a paradise for him, when it's all said and done. I could give him everlasting peace.

I owe him for the gifts he's given me.

[Is he being honest?

... He would rather not answer. The thought of it is beautiful though, isn't it? Lucifer casting mercy on a few humans, so Sam could have an oasis in the middle of heaps and heaps of human bones?]

But I'm sure you doubt me right now, with things as they are.

I can't fault your assumptions.
