Castiel appreciated the gestures from Ben, and inwardly promised that he wouldn't tell anyone about Ben crying. Honestly, someone like Claire would probably guess anyway, a woman's intuition was good like that, but many boys, Winchester in particular, wouldn't want something like that talked about. So he hugged Ben back, and vowed to make sure he never needed to cry like that again.
"We'll make it all okay," he offered a half smile. "It'll take time and a lot of effort from all of us, but we'll make Sam better. And he can be just Sam again."
He didn't mention Ruby. Honestly, he didn't know if she even could be saved any more.
"A note?" He was actually amused at the resourcefulness Ben had shown. "You know they'll still be worried about you."
