"Where I'm from.. you were actually helping me out with Dean a few days ago. I've been trying to close the gates of hell. The trials I had to do.. well about to do I've been really out of it. I don't know if these trials are purifying me or what.. but I've had a fever for days and it's making me weak." he said honestly to him, it wasn't like he could lie to Castiel. He'd find out sooner or later.
"Now.. I am not sure what's going to happen to me because I can't finish the trials because I am stuck here. Like right now I feel I have a very bad cold.. that's just not getting better." he needed to get all of this off his chest with someone that wound kind of understand him.
