[It's a question that Castiel might have worried more over answering if he had more tact, but seeing how Isaac wants to know, he's going to be direct with him.]
You would go to Purgatory. All monsters go there.
[At least where Castiel is from. He can't be certain they're from the same version of Earth.]
I would have to know more about your father before I could presume to guess where he might go.
[How to explain Purgatory? Castiel hesitates for a moment, complete silence on the line as he considers how much to say. It's not something that's supposed to be shared with the living, but he has to tell Isaac something.]
It's not a pleasant place. It's hunt or be hunted. It's miles and miles of forest and mountains and filled with bloodthirsty souls.
[There is some kind of upside to this, though, which he soon adds.]
But that's only the case where I come from. Your world could be very different.
[ Isaac goes deathly silent, hunt or be hunted. That's literally all his life is ever going to be, even after he dies... Even after he dies he'll still be hunted.
He sucks in a wavering breath, trying to process what he's just heard. But then Castiel seems to try to do damage control and it doesn't even make him feel better. ]
Can you die in purgatory? Wouldn't that defeat the point?
[That's a question Castiel had pondered over while trapped in that place himself. What happened to someone who died in a place that was already meant for the dead?
Castiel had a theory about that, and so he shares it.]
I can't be certain, but I think it's much like this place. If you die, you eventually come back.
[Doomed to die and revive over and over again for eternity. No, it's not a pleasant fate.]

[ It's not much of an answer to what Castiel said, really an answer can't be a question but... ]
Would my dad - would he...?

[ It doesn't sound good. And being called a monster doesn't sit well with him but he doesn't say anything. ]
Maybe I'll tell you about him sometime.
[ Probably not. ]

[ Hear that sigh, Castiel? ]
Thanks for answering my questions.

... As I said, this may all be different in your world. [The werewolves themselves certainly look to be different enough.] But you're welcome.
