The emotions were so strong they were caught somewhere between his throat and his chest. There was relief that he had at last found his friend. Confusion at his appearance and the appearance of this place around them. Deeper than that was the terrible guilt, those things which he would have to explain to this younger version of Dean. No doubt the disappointments would be similar, Cas did not look forward to those looks. He was already so tired.
Tired enough that he leaned against Dean more than he intended as he clapped his friend on the back and attempted to find some way to bite down the emotion that reddened his face. “Christo?” Cas puzzled over the word for a moment uncertain what Dean had meant about the question. Realization slowly dawned, “You are testing me? I’m not possessed.” At least he didn’t believe he was possessed. He would be able to sense his own possession surely even in his depleted condition.
