Castiel nodded slightly, glad that Ruby knew to step out for this part. He gently took one of Margareta's hands in both of his, murmuring prayers so quietly only she would be able to hear him. He prayed for her soul, for his Father to protect her as she journeyed into the next life.
He hoped her faith would bring her some comfort at this time, and maybe his presence too. Time was rapidly running out, and he was relieved he was able to be here, to offer her her last rites.
Once finished he leaned over and gently kissed the top of her head, before sitting back once more.
