OOC!
Sam genuinely DOES feel like Castiel would be useful in the hunting field, but after his chat with Jules he's a little more hesitant about pushing Cas in that direction. He'll be posting to him again soon!
Castiel, your situation suuucks. Also: welcome, officially, to team free will! You have to make your own decisions and figure things out for yourself now! No more orders, just doing what you think is the right thing to do.
...I can see how stumbling into free will after thousands of years of that would be confusing. Hopefully they can find some way to help him settle in a place he feels he's making a difference/feels like he belongs.
