There was definitely still news that had to be broken, even to someone like Adam who had both heard and been through some terrible things already. While he might think that he'd reached a point where nothing would surprise him, even Castiel -- who had lived much longer than Adam, even taking into account his Hell years -- was surprised on a regular basis.

He wasn't going to hold back the information, though he braced himself for Adam's bad reaction. Not that Castiel could blame him in this case.

"Michael's inscribed symbols on your ribs that allow him to know your location no matter where you are," he said. "I don't know if that accounts for warding." Castiel honestly couldn't say whether Michael had the sort of power to break through wards that were made specifically against him.

Unfortunately, it meant that Michael might know where Adam was now, and if he was able to track him and unearth the resistance bunker, then that was going to leave Castiel with a whole new set of problems.
